June 27, 2022 – Data Product Release: Spatial Statistical Data Fusion Version 2 Level 3 Near-Surface Air Temperature

The AIRS (Atmospheric Infrared Sounder) Science Team and NASA GES DISC (Goddard Earth Sciences Data and Information Services Center) have released the spatial statistical data fusion (SSDF) near-surface air temperature (NSAT) product, created by fusing Level 2 NSAT from AIRS and SNPP-CLIMCAPS1 and utilizing data from in situ weather stations. The SSDF product has improved bias, variance, and uncertainty estimates relative to the input remote sensing products. NSAT is an essential climate variable for application areas such as urban heat and wildfire.

For further details and links to the datasets please see the data release announcement on the GES DISC website.

August 13, 2021 – Data release: Climate Hyperspectral Infrared Radiance Product (CHIRP) Level 1 products

The CHIRP algorithm converts radiances to a common spectral and radiometric calibration derived from infrared sounders aboard three Earth Observing System (EOS) polar-orbiting satellite platforms: AIRS (Atmospheric Infrared Sounder) on Aqua; CrIS (Cross-track Infrared Sounder) instrument on the Suomi National Polar-orbiting Partnership (SNPP) platform; and CrIS on the National Oceanic and Atmospheric Administration NOAA-20 platform (also known as, Joint Polar Satellite System, JPSS-1).

Details are provided in the CHRP Data Release Announcement at NASA Goddard's Data and Information Services Center.


June 11, 2021 – CLIMCAPS V2 AIRS Data Release

On behalf of the AIRS project, the Sounder Science Investigator-led Processing Systems (Sounder SIPS), and the AIRS and Sounder Science Teams, we would like to announce the public release of data from the Community Long-term Infrared Microwave Coupled Atmospheric Product System (CLIMCAPS) retrieval algorithm that utilizes radiances from all US sounders on Aqua, SNPP, and JPSS-1/NOAA-20, for the full duration of these missions. CLIMCAPS addresses critical needs of the climate, weather and composition science communities for data products that are consistent across platforms in order to guarantee long-term data continuity.

June 20, 2020 – Aqua AIRS Version 7 data now available

The AIRS (Atmospheric Infrared Sounder) Science Team and the NASA Goddard Earth Sciences Data and Information Services Center (GES DISC) are pleased to announce the release of AIRS Version 7 Level 2 and Level 3 data products.

The Version 7 data represent a significant improvement over AIRS Version 6 Level 2 products, especially with the AIRS "IR only" product. Several algorithmic improvements have been made by the AIRS Project and the AIRS Science Team.

More about the Version 7 release can be found on the Goddard Earth Sciences Data and Information Services Center web site.
