The Global Surface Emissivity Spectral Atlas (GSESA) Product Release Announcement
Posted: Wed Aug 13, 2025 3:22 pm America/New_York
The National Airborne Sounder Testbed-Interferometer (NAST-I) team announces public release of newly versioned science products:
The Global Surface Emissivity Spectral Atlas (GSESA) Database Product.
The Global Surface Emissivity Spectral Atlas (GSESA) database contains global, monthly climatology infrared emissivity functional Empirical Orthogonal Function (EOF) scores in 0.25 x 0.25 latitude-longitude resolution. An eigenvector file and a reader file allow customers to produce emissivity spectra. The emissivity functional EOF scores were developed using the Infrared Atmospheric Sounding Interferometer (IASI) instrument on the METOP-A, METOP-B, and METOP-C satellites for the period 2007-07-01 to 2025-01-31.
Information about this new data product, including data availability, user documentation, relevant links, and tools for working with the data, can be found at:
https://asdc.larc.nasa.gov/project/GSESA/GSESA_V01
These data products are also available from the ASDC via the following options:
