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.

The spatial resolution of the EDR is 750 meters and data are collected during day and night passes which provides global coverage at a temporal resolution of approximately every 12 hours. VIIRS cloud height data distributed by the NESDIS Data Exploitation (NDE) system and obtained from the Comprehensive Large Array-Data Stewardship System (CLASS) are distributed in single 86-second granules in NetCDF-4 format with metadata attributes included.

This data set contains AMSU-B (Advanced Microwave Sounding Unit-B) data from the NOAA POES satellites (K/L/M/N). These data were retrieved from the NOAA CLASS archive. The data are in Level 1-b format and cover the T-REX period (1 March to 30 April 2006).

This data set contains HIRS/3 (High Resolution Infrared Radiation Sounder) data from the NOAA POES satellites (K/L/M/N). These data were retrieved from the NOAA CLASS archive. The data are in Level 1-b format and cover the T-REX period (1 March to 30 April 2006.

The Advanced Microwave Sounder Unit - A (AMSU-A) is an instrument onboard the NOAA/POES and EUMETSAT/MetOp Polar-orbiting satellite series. NOAA/POES and MetOp Polar-orbiting satellites circle the Earth approximately 14 times per/day from an altitude of approximately 520 miles above the Earth. The Earth's rotation allows the satellites to see different views with each orbit, and each satellite provides two complete views of the same location each day. AMSU-A is a microwave sounder with 15 channels used primarily for deriving atmospheric temperature profiles. AMSU-A Level-1b products from NOAA and EUMETSAT provide geolocated radiances at 48 km resolution. These data are used by NOAA’s National Environmental Satellite, Data, and Information Service (NESDIS) to generate NOAA Unique Level-2 products. AMSU-A Level-1b products are produced by NOAA and EUMETSAT and are distributed by NOAA's Comprehensive Large Array-Data Stewardship System (CLASS).

NEW GOES-19 Data!! On April 4, 2025 at 1500 UTC, the GOES-19 satellite will be declared the Operational GOES-East satellite. All products and services, including NODD, for GOES-East will transition to GOES-19 data at that time. GOES-19 will operate out of the GOES-East location of 75.2°W starting on April 1, 2025 and through the operational transition. Until the transition time and during the final stretch of Post Launch Product Testing (PLPT), GOES-19 products are considered non-operational regardless of their validation maturity level. Shortly following the transition of GOES-19 to GOES-East, all data distribution from GOES-16 will be turned off. GOES-16 will drift to the storage location at 104.7°W. GOES-19 data should begin flowing again on April 4th once this maneuver is complete.

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.

The Cross Track Infrared Sounder (CrIS) on-board the Suomi-NPP is a Fourier Transform Spectrometer that operates in tandem with the Advanced Technology Microwave Sounder (ATMS) to detect and measure atmospheric temperature and moisture profiles. This metadata record encompasses all CrIS Raw Data Records (RDRs), which include science, diagnostic, memory dump and telemetry RDRs. CrIS RDR products are produced by the NOAA Environmental Satellite, Data, and Information Service (NESDIS) and are distributed by the Comprehensive Large Array-Data Stewardship System (CLASS).
