TEMPO cloud pressure and fraction (O2-O2 dimer) V03 (PROVISIONAL)

Published by NASA/LARC/SD/ASDC | National Aeronautics and Space Administration | Catalog Last Checked: September 08, 2026 at 11:39 PM | Dataset Last Updated: September 08, 2026
O2-O2 cloud Level 2 files provide cloud information at TEMPO’s native spatial resolution, ~10 km^2 at the center of the Field of Regard (FOR), for individual granules. Each granule covers the entire North-South TEMPO FOR but only a portion of the East-West FOR. The files are provided in netCDF4 format, and contain information on effective cloud fraction (ECF), cloud optical centroid pressure (OCP), ancillary data, processing quality flags, etc. The ECF is derived from reflectance at 466 nm. The OCP is derived from O2-O2 slant column density. The cloud retrieval uses Look Up Tables (LUTs) of reflectance and air mass factors, GEOS-CF meteorology, and GLER surface albedo. These data reached provisional validation on December 9, 2024.
