TEMPO cloud pressure and fraction (O2-O2 dimer) V04 (PROVISIONAL)
Listed in NASA Earthdata CMR and NASA Data Portal — shown once because both records carry DOI 10.5067/is-40e/tempo/cldo4_l2.004
O2-O2 cloud Level 2 (PROVISIONAL) 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.
Description
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-O2slant column density. The cloud retrieval uses Look Up Tables (LUTs) of reflectance and air mass factors, GEOS-CF meteorology, and GLER surface albedo.
