TEMPO geolocated Earth radiances twilight V04 (PROVISIONAL)
Listed in NASA Earthdata CMR and NASA Data Portal — shown once because both records carry DOI 10.5067/is-40e/tempo/radt_l1.004
Level 1 twilight radiance files provide radiance measured during twilight hours to capture city lights at TEMPO’s native spatial resolution, ~10km^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 radiometrically calibrated and geolocated radiances for the UV and visible bands, corresponding noise, geolocation, viewing geometry, quality flags and other ancillary information.
The product is produced using the L0-1b processor which includes image processing steps to produce radiometrically calibrated radiances with nominal navigation. These data reached provisional validation on December 9, 2024.
