The National Airborne Sounder Testbed-Interferometer (NAST-I) team announced the public release of newly versioned science products: The Global Surface Emissivity Spectral Atlas (GSESA) Database.
The 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 July 1, 2007 to January 31, 2025.
