This accession contains the data descriptions for the OSTM/Jason-2 Ancillary data files, which is served through the NOAA/NESDIS Comprehensive Large Array-data Stewardship System (CLASS): http://www.class.noaa.gov

OSTM/Jason-2 is a follow-on mission to Jason-1, which takes over and continues the TOPEX/Poseidon and Jason-1 missions. OSTM/Jason-2 involves Centre National d'Etudes Spatiales (CNES), NASA and 2 new partners: the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) and NOAA in order to 1) ensure continuity of high quality measurements for ocean science, and 2) provide operational products for assimilation and forecasting applications. OSTM/Jason-2 was launched on 20 June 2008 and reached its nominal repetitive orbit on 4 July 2008. The start of cycle 1 occurred on 12 July 2008.

These Ancillary data files are used to generate Level-2 products. They include both static tabular data files and dynamic files which change/grow over time. They are mission specific files used in the production of Level-2 products. All members of the Ancillary data family (J2-ANC) were made unrestricted on 15 December, 2008.

Other data/products associated with OSTM/Jason-2 are also provided through CLASS. They are: Level-2 Geophysical Data Records (GDRs), auxiliary data files used to generate Level-2 products, quality reports from the near real-time altimetry validation system (NRTAVS), orbit information of JASON-2 satellite and telemetry data. The descriptions of these data products can also be accessed in other accessions at NODC.

The National Centers for Environmental Information in partnership with the Cooperative Institute for Climate and Satellites - North Carolina is reprocessing the GOES (Geostationary Operational Environmental Satellite) Variable (GVAR) period of record: 1994-2015. GridSat GOES represents a reformatted, remapped and calibrated GOES brightness temperatures and reflectance provided in Climate and Forecasting (CF)-compliant netCDF format. This is similar to the current GridSat-B1 CDR, but at a higher spatial and temporal resolution. The data are provided near the original spatial resolution of the infrared channels (4 km) on an equal angle grid (0.04 degrees). Data are mapped to a region spanning the view of GOES East and West (150 deg East to 5 deg East). The data are provided hourly, with all data mapping to the nearest hour. Currently, the data are limited to variables including the observations from the GOES satellites: 5 total channels. However, future efforts are planned to include some basic cloud information (cloud probability, temperature, etc.). Other possible updates include: improved coverage by expanding the GOES inventory (currently, gaps exist in the CLASS archive) and expand to the predecessor to the GOES Imager: GOES VISSR, which would expand coverage back to the 1980s.

OSTM/JASON-2 is a follow-on mission continuing the TOPEX/Poseidon and Jason-1, and is designed to ensure continuity of high quality measurements for ocean science and to provide operational products for assimilation and forecasting applications. The Jason-2 satellite was launched on 20 June 2008 and reached its nominal repetitive orbit on 4 July 2008.

The level-2 X-GDR are available as 3 datatypes: Operational Geophysical Data Records (OGDR), Interim Geophysical Data Records (IGDR) and final Geophysical Data Records (GDR). The OGDRs are near-real-time records and are generated every 3-5 hours. They are based on orbits from DORIS propagator and forecast meteorological fields for the geophysical corrections. The IGDRs are based on preliminary DORIS ephemeris, analyzed meteorological grids, and preliminary auxiliary data files. The IGDRs have a latency of 1 - 2 days. The S-IGDR is a superset of the IGDR, containing the original radar echo "waveform" data. The GDRs are based on final high-precision DORIS (perhaps combined with GPS) ephemeris, final meteorological grids, ancillary and auxiliary data files. The S-GDR is a superset of the GDR, containing the waveform data. The S-GDRs are generated every 10 days. Sea Surface Height Anomaly (SSHA) files are available for IGDR and GDR. All files are available in NetCDF format and the OGDRs are also available in BUFR format. Jason-2 level-2 X-GDR data are distributed through the NOAA/NESDIS Comprehensive Large Array-data Stewardship System (CLASS:http://www.class.noaa.gov).

Jason-2 level-2 X-GDR data are distributed through the NOAA National Oceanographic Data Center via FTP at ftp://data.nodc.noaa.gov/pub/data.nodc/jason2, HTTP at http://data.nodc.noaa.gov/jason2 and OPeNDAP at http://data.nodc.noaa.gov/opendap/jason2 and archived by NODC (NODC) as accession number 0043269 (http://www.nodc.noaa.gov/cgi-bin/search/prod/accessionsView.pl/details/43269). Archival storage is provided by the Comprehensive Large Array-data Stewardship System (CLASS:http://www.class.noaa.gov).

This dataset contains a high quality operational Environmental Data Record (EDR) of suspended matter from the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument onboard the Suomi-NPP satellite and is produced by the NOAA Satellite and Information Service (NESDIS). The retrieval algorithm is based on a legacy product originally developed for the Moderate Resolution Imaging Spectroradiometer (MODIS) sensor but is adapted and improved upon for use by VIIRS. The aerosol mask indicates the presence of either smoke or dust. The dust and smoke masks indicate the presence of dust and smoke, respectively. Because the presence of smoke and dust are independently derived, a given pixel can be identified with both dust and smoke. The product also includes data quality information for on-earth pixels. Note, the binary aerosol, dust, and smoke mask values are dimensionless quantities. The algorithm utilizes fourteen different spectral bands ranging from 0.412 to 12 microns. The spatial resolution is 1 kilometer (km) and the temporal resolution provides global coverage daily. VIIRS Aerosol Detection data distributed by the NESDIS Data Exploitation system (NDE) and obtained from the Comprehensive Large-Array Stewardship System (CLASS) are distributed as single 86-second granules in NetCDF-4 format with metadata attributes included.

This data collection consists of archived Geostationary Operational Environmental Satellite-R (GOES-R) Series Advanced Baseline Imager (ABI) Level 0 data from the GOES-East and GOES-West satellites in the operational (OPS) and the post-launch test (PLT) phases. The GOES-R Series provides continuity of the GOES mission through 2035 and improvements in geostationary satellite observational data. GOES-16, the first GOES-R satellite, began operating as GOES-East on December 18, 2017. GOES-17 began operating as GOES-West on February 12, 2019. GOES-T launched on March 1, 2022, and was renamed to GOES-18 on March 14, 2022. GOES-U, the final satellite in the series, is scheduled to launch in 2024. ABI is a multi-channel passive imaging radiometer observing the Western Hemisphere. The ABI Level 0 data are composed of Consultative Committee for Space Data Systems (CCSDS) packets containing the science, housekeeping, engineering, and diagnostic telemetry data downlinked from the instrument. The Level 0 data files also contain orbit and attitude/angular rate packets generated by the GOES spacecraft. Each CCSDS packet contains a unique Application Process Identifier (APID) in the primary header that identifies the specific type of packet, and is used to support interpretation of its contents. Users may refer to the GOES-R Series Product Definition and Users’ Guide (PUG) Volume 1 (Main) and Volume 2 (Level 0 Products) for Level 0 data documentation. Related instrument calibration data and Level 1b processing information are archived and available for order at the NOAA CLASS website. The ABI Level 0 data files are delivered in a netCDF-4 file format, however, the constituent CCSDS packets are stored in a byte array making the data opaque for standard netCDF reader applications. The ABI Level 0 data files are packaged in hourly tar files (data bundles) by satellite for the archive. Recently ingested archive tar files are available for 14 days on an anonymous FTP server for users to download. Data archived on offline tape may be requested from NCEI.

This dataset contains a high quality operational Environmental Data Record (EDR) of snow cover from the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument onboard the Suomi-NPP satellite and is produced by the NOAA Satellite and Information Service (NESDIS). This product provides both binary (snow or no-snow) and fractional snow cover for cloud-free areas during daytime. The product also includes quality information which provides support information on the quality of snow retrievals. The algorithm utilizes VIIRS visible bands I1 (0.640 micron), I2 (0.865 micron), I3 (1.61 micron), I4 (3.74 micron), and I5 (11.5 micron) at a spatial resolution of 375 meters. VIIRS Snow Cover products distributed by the NESDIS Data Exploitation system (NDE) and obtained from the Comprehensive Large-Array Stewardship System (CLASS) are distributed in single 86-second granules in NetCDF-4 format with metadata attributes included.

This dataset contains a high quality operational Environmental Data Record (EDR) of volcanic ash from the Visible Infrared Imaging Radiometer (VIIRS) instrument onboard the Suomi-NPP satellite and is produced by the NOAA Satellite and Information Service (NESDIS). The EDR contains two images with pixel values identifying volcanic ash cloud height and volcanic ash mass loading. The product also includes two types of data quality information, one indicator describes the quality of the volcanic ash detection, and the second indicator provides information about the quality and ash characteristics of the retrieval for on-earth pixels. The algorithm utilizes VIIRS sensor data from the M14 (8.55mm), M15 (10.763mm), and M16 (12.013mm) spectral bands and provides global coverage every 12 hours. VIIRS volcanic ash data distributed by the NESDIS Data Exploitation (NDE) system and obtained from the Comprehensive Large Array-Data Stewardship System (CLASS) are distributed as single 86-second granules in NetCDF-4 format with metadata attributes included.

This dataset represents sediment composition class predictions from a sediment spatial model developed for the New York offshore spatial planning area. The predictive spatial model of mean grain size was developed building upon the data compilation and analytical framework laid out by Goff et al. (2008) and Poppe et al. (2005).

NEW GOES-19 Data!!! GOES-19 products at the Provisional maturity level have begun streaming. Data files will be available between Provisional and the Operational Declaration of the satellite, however, these data are subject to the caveat that they are "GOES-19 Preliminary, Non-Operational Data".

NEW GOES 16 Reprocess Data!! The reprocessed GOES-16 ABI L1b data mitigates systematic data issues (including data gaps and image artifacts) seen in the Operational products, and improves the stability of both the radiometric and geometric calibration over the course of the entire mission life. These data were produced by recomputing the L1b radiance products from input raw L0 data using improved calibration algorithms and look-up tables, derived from data analysis of the NIST-traceable, on-board sources. In addition, the reprocessed data products contain enhancements to the L1b file format, including limb pixels and pixel timestamps, while maintaining compatibility with the operational products. The datasets currently available span the operational life of GOES-16 ABI, from early 2018 through the end of 2024. The Reprocessed L1b dataset shows improvement over the Operational L1b products but may still contain data gaps or discrepancies. Please provide feedback to Dan Lindsey (dan.lindsey@noaa.gov) and Gary Lin (guoqing.lin-1@nasa.gov). More information can be found in the GOES-R ABI Reprocess User Guide.


NOTICE: As of January 10th 2023, GOES-18 assumed the GOES-West position and all data files are deemed both operational and provisional, so no ‘preliminary, non-operational’ caveat is needed. GOES-17 is now offline, shifted approximately 105 degree West, where it will be in on-orbit storage. GOES-17 data will no longer flow into the GOES-17 bucket. Operational GOES-West products can be found in the GOES-18 bucket.

GOES satellites (GOES-16, GOES-17, GOES-18 & GOES-19) provide continuous weather imagery and monitoring of meteorological and space environment data across North America. GOES satellites provide the kind of continuous monitoring necessary for intensive data analysis. They hover continuously over one position on the surface. The satellites orbit high enough to allow for a full-disc view of the Earth. Because they stay above a fixed spot on the surface, they provide a constant vigil for the atmospheric "triggers" for severe weather conditions such as tornadoes, flash floods, hailstorms, and hurricanes. When these conditions develop, the GOES satellites are able to monitor storm development and track their movements. SUVI products available in both NetCDF and FITS.

This archived Paleoclimatology Study is available from the NOAA National Centers for Environmental Information (NCEI), under the World Data Service (WDS) for Paleoclimatology. The associated NCEI study type is Tree Ring. The data include parameters of tree ring with a geographic location of North Dakota, United States Of America.

This dataset contains a high quality operational Environmental Data Record (EDR) of Ice Thickness and Age from the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument onboard the Suomi-NPP satellite and is produced by the NOAA Environmental Satellite, Data, and Information Service (NESDIS). This daily product provides estimates of sea and lake ice thickness and age for all pixels covered with ice. The current ice thickness and age design has the ability to estimate sea and lake ice thickness up to 3 meters under both clear and cloudy conditions at night. The algorithm also works during daytime though estimates are more uncertain. The product also includes quality information which provides support information on the quality of ice estimates. There are no direct VIIRS channels related to the algorithm which actually relies on other VIIRS products such as cloud mask, ice surface temperature, and ice surface albedo that would use some or all VIIRS channels for their retrievals. The VIIRS Ice Thickness and Age products distributed by the NESDIS Data Exploitation (NDE) system and obtained from the Comprehensive Large-Array Stewardship System (CLASS) are distributed in single 86-second granules in NetCDF-4 format with metadata attributes included.

Benthic habitat maps for the nearshore, shallow (< 30 m) coastal waters of Midway Atoll in the Northwestern Hawaiian Islands (NWHI) and the Papahanaumokuakea Marine National Monument. NOAA's National Centers for Coastal Ocean Science (NCCOS) produced these data to support coral reef research and management. Habitat regions were digitally identified using visual interpretation of orthorectified satellite imagery with a minimum mapping unit (MMU) of approximately 100 square meters (1/40 acre). A slightly different benthic habitat classification scheme was used for the NWHI compared to the Main Hawaiian Islands (MHI) and other regions across the Pacific (e.g., American Samoa, Guam, and CNMI). While many classes are similar, they are not categorized as biological cover types, geomorphological structure types, and geographic zones. Instead, a hierarchical scheme was used to flexibly denote substrate category (e.g., unconsolidated and hardbottom), structure (e.g., linear reef or pavement), and cover (e.g., coral, coralline algae, or macroalgae). A total of 45 detailed benthic habitat classes were identified within the NWHI. For simplification and to more easily distinguish cover types, these are presented in a set of 7 aggregated benthic habitat classes including 5 hardbottom substrate classes (live coral, coralline algae, macroalgae, uncolonized, and unknown biological cover) and 2 unconsolidated substrate classes (macroalgae and uncolonized). Query an aggregated polygon to get the detailed benthic habitat classification at the clicked location.

This data set contains a high quality Environmental Data Record (EDR) of nighttime cloud optical and microphysical properties (NCOMP) from the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument onboard the Suomi-NPP satellite and is produced by the NOAA Satellite and Information Service (NESDIS). The EDR contains Cloud Optical Depth (COD), Cloud effective Particle Size (CPS), and Liquid and Ice Water Path (LWP and IWP). Liquid and ice water path are calculated subsequently from COD and CPS. The NCOMP algorithm uses VIIRS bands M7, M15, and M16. The EDR provides global coverage daily at a spatial resolution of 750 meters at nadir. VIIRS NCOMP data distributed by the NESDIS Data Exploitation (NDE) system and obtained from the Comprehensive Large-Array Stewardship System (CLASS) are distributed as single 86-second granules in NetCDF-4 format with metadata attributes included.

The original data source is provided by the Space Weather Prediction Center - SWPC, which is linked to the National Oceanic and Atmospheric Administration - NOAA from US Department of Commerce.

Data description:

• radio_flux_10.7cm: the solar radio flux at 10.7 cm (2800 MHz) is an indicator of solar activity. It is also called the F10.7 index and is one of the longest running records of solar activity. Radio emissions originate high in the chromosphere and low in the corona of the solar atmosphere.
• sesc_sunspot_number: it refers to the number of sunspots computed on a given day. Also called Wolf's number of sunspots, it is given by R = k(10g + s), where k is a scalable factor indicating the combined effects of observation conditions, g is the number of active regions and s the number of sunspots in all these groups.
• sunspot_area: it refers to the sum of the corrected area of all observed sunspots. It is measured in units of millionths of the solar hemisphere.
• goes15_xray_bkgd_flux: it corresponds to the daily average background X-ray flux that is measured by the SWPC primary GOES satellite. To calculate this value, sensors register 24 X-ray measures for a given day, one for each hour. Then, the SWPC creates 3 groups of periods of 8 hours. For these groups, the SWPC registers the lowest values of flux, creating 3 minimal values, one for each group. Then, they calculate the average between the minimum values of the first and the third group. After the average calculation, they must compare this value to the minimal value of the second group. The minimum value from the last comparison gives the result of the X-ray background flux.
• mwl_alpha: binary attribute indicating the presence of apha magnetic class in any observed spot.
• mwl_beta: binary attribute indicating the presence of beta magnetic class in any observed spot.
• mwl_gamma: binary attribute indicating the presence of gamma magnetic class in any observed spot.
• mwl_beta_gamma: binary attribute indicating the presence of beta-gamma magnetic class in any observed spot.
• mwl_delta: binary attribute indicating the presence of delta magnetic class in any observed spot.
• mwl_beta_delta: binary attribute indicating the presence of beta-delta magnetic class in any observed spot.
• mwl_beta_gamma_delta: binary attribute indicating the presence of beta-gamma-delta magnetic class in any observed spot.
• mwl_gamma_delta: binary attribute indicating the presence of gamma-delta magnetic class in any observed spot.
• c_class_flares: number of c class flares observed.
• m_class_flares: number of m class flares observed.
• x_class_flares: number of x class flares observed.

The data collected refer to the period between january 01, 1997 to january 15, 2017.
