TEMPO formaldehyde total column V03 (PROVISIONAL)

Published by NASA/LARC/SD/ASDC | National Aeronautics and Space Administration | Metadata Last Checked: October 15, 2025 | Last Modified: 2025-08-06

Formaldehyde Level 2 files provide trace gas 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 vertical columns, ancillary data used in air mass factor calculations and reference sector corrections, and retrieval quality flags. The retrieval uses a three-step approach: (1) spectral fitting of slant columns, (2) air mass factor calculation and derivation of vertical columns, and (3) reference sector corrections. These data reached provisional validation on December 9, 2024.
