The goal of creating this product is to allow users to begin working with data from the CrIS instrument on-board the recently launched NOAA-21 / JPSS-2 (J2) satellite. The J2 beta product was generated using an updated version of the software that is used to generate the Version 3 SNPP and JPSS-1 (J1) products, which are currently available from GES DISC. Changes were made to allow J2 processing, but the underlying algorithm theoretical basis remains the same. It should be noted that work on refining the J2 calibration parameters is ongoing, and the parameters used in this release are preliminary. A future Version 4 set of products is planned for release after J2 has reached validated status, which will include optimized J2 parameters and will use a single software version for all three instruments incorporating various algorithm improvements. The Cross-track Infrared Sounder (CrIS) Level 1B Full Spectral Resolution (FSR) data files contain radiance measurements along with ancillary spacecraft, instrument, and geolocation data of the CrIS instrument on the Joint Polar Satellite System-2 (JPSS-2) platform. This platform is also know as NOAA-21 (National Oceanic and Atmospheric Administration). The JPSS-2 mission with CrIS instrumentation is a follow-on to the Suomi National Polar-orbiting Partnership (SNPP) mission. The CrIS instrumentation and data processing system is nearly identical to that of the SNPP satellite. CrIS is designed to be used with the ATMS (Advanced Technology Microwave Sounder) instrument. Processing the data from both of these instruments together is referred to as CrIMSS (Cross-Track Infrared and Microwave Sounder Suite). The FSR files have 2,223 channels (2211 apodized channels): 637 (633) shortwave channels from 3.9 to 4.7 microns (2555 to 2150 cm-1), 869 (865) midwave channels from 5.7 to 8.05 microns (1752.5 to 1242.5 cm-1), and 717 (713)longwave channels from 9.1 to 15.41 microns (1096.25 to 648.75 cm-1). Each CrIS field-of-regard (FOR) contains 9 field-of-views (FOVs) arranged in a 3X3 array. The Level 1B files contain 30 FORs in the cross track direction and 45 in the along track direction. Data products are constructed on six minute boundaries. An issue has been observed in J2 CrIS data that impacts calibration of observations for a period of several minutes during each orbit. The issue occurs in the southern hemisphere during the descending part of the orbit, near a satellite solar zenith angle of -118 degrees. There is significant variability in affected latitudes throughout the year. The issue is indicated by non-zero quality flags in the Level 1B product. The root cause is believed to be variation in calibration views due to rapid instrument temperature changes after the J2 satellite passes from the Earth's shadow into direct sunlight. Potential solutions are being evaluated for implementation in a future product version.

Level 3 parameters from HIRS/2 and MSU radiances using the Improved Initialization Inversion (3I) classification retrieval scheme by the Laboratoire de Meteorologie Dynamique (Ecole Polytechnique) averaged over 1 day and mapped on to a 1x1 degree grid. This data was run as part of the NASA TOVS Pathfinder project and designated as Path-B. This dataset contains data from the NOAA-10 satellite.

LIMSN7L1RAT is the Nimbus-7 Limb Infrared Monitor of the Stratosphere (LIMS) Level-1 Radiance Data product. It contains calibrated, earth-located radiances, as well as housekeeping information, instrument status, and data quality information. Radiances of the Earth limb were measured both day and night in six spectral bands (6.2, 6.3, 9.6, 11.3, and two at 15 micrometers). Though calibrated, the radiances are not corrected for instrument effects such as field-of-view, electronic delay, and spacecraft motion. Each file contains one orbit of data (~14 orbits per day). LIMS is a limb profiler and spatial coverage is near global between latitude -64 and +84 degrees. Vertical coverage is from about 10 to 50 km (O3 channel to 65 km), with vertical resolution of about 1.5 km. The data are available from 25 October 1978 through 30 May 1979. The principal investigators for the LIMS experiment were Dr. James M. Russell, III from NASA Langley and Dr. John Gille from NCAR. This product was previously available from the NASA National Space Science Data Center (NSSDC) under the name LIMS Radiance Archival Data with the identifier ESAC-00032 (old id 78-098A-01B).

:A “Digital Divide” in data representation exists between the preferred way of data access by the hydrology community (i.e., as time series of discrete spatial objects) and the common way of data archival by NASA earth science data centers (i.e., as continuous spatial fields, one file per time step). This Divide has been an obstacle between hydrology data users (e.g., CUAHSI HIS, HydroShare) and the NASA Goddard Earth Sciences Data and Information Services Center (GES DISC). The GES DISC (one of 12 NASA Earth Observing System (EOS) data centers) processes, archives, documents, and distributes data from Earth science missions and related projects, including hydrologic land surface data. The latter are part of the GES DISC Water & Energy Cycle data holdings. Of the many related data services available to users, the NASA Giovanni (Geospatial Interactive Online Visualization and Analysis Infrastructure) is the best known and most used (cited in more than 2000 peer-reviewed research publications). Giovanni provides a relatively simple way for researchers to conduct exploratory investigations with a variety of NASA Earth observation data and related data sets. Among Giovanni’s suite of plotting options, the time series is probably of the most interest to hydrology data users (and is the second most popular among users in general). However, for optimal access to GES DISC data along the time dimension, the data as archived must be reorganize to some way that is optimal for that mode of access. Given the importance of bridging the Digital Divide, the GES DISC has (1) developed “Data Rods,” a set of REST endpoints for long time series; (2) improved the performance of Giovanni’s time series plotting option; and (3) assisted the University of Texas-Austin in developing and supporting the Data Rods Explorer (DRE), a HydroShare app that combines data from the first two sources. As part of NASA data centers’ overall transitioning to the cloud, the GES DISC has been investigating “Giovanni in the cloud.” Though still under development, the prototype Giovanni Cloud-Optimized Data Store (CODS) has already demonstrated a significant performance increase in time series capabilities—5-10 times faster than the current Data Rods endpoints. The GES DISC aims to continually explore and implement appropriate technologies to improve its data services, in response to user needs of the hydrology community.

This is the MODIS/Aqua subset along MLS field of view track. The goal of the subset is to select and return MODIS data that are within +-100 km across the MLS track. I.e. the resultant MODIS subset swath is sought to be about 200 km cross-track. However, the original MYD05_L2 has data of 5- and 1-km pixels. Thus, MAM05S0 cross-track width is 41- and 201-pixels, depending on the parameter. Along-track, all MODIS pixels from the original product are preserved. In the standard product, the MODIS level-2 atmospheric precipitable water product consists of total atmospheric column water vapor amounts (and ancillary parameters) over clear land areas of the globe, over extended clear oceanic areas with the Sun glint, and above clouds over both land and ocean. These estimates are based on a near-infrared algorithm using only daytime measurements with solar zenith angle less than 72 degrees. The retrieval algorithm relies on observations of water vapor attenuation of near-infrared solar radiation reflected by surfaces and clouds. The product is produced only over areas that have reflective surfaces in the near-infrared. The infrared-derived precipitable water vapor generated for both daytime & nighttime conditions as one component of another MODIS product (MYD07) is also provided as a part of this product. (The shortname for this product is MAM05S0).

This product is a multi-variate data compilation that reconciles the variation scales of these multiple measurements from varies resources, merges and maps them into a comprehensive description of the near-surface atmospheric properties together with the land surface property variations on diurnal-to-decadal time scales. Many of these data products, especially those based on surface measurements, are spatially and/or temporally sparse or incomplete in coverage, so procedures were developed to fill missing values. The data product is comprised of a sequence of daily global files, where quantities are mapped into 1.0-degree equivalent equal-area grid, with time sampling is reported at daily or 3-hourly intervals. The time period overlap among the products covers 10 years from 1998 to 2007.
