TEMPO NO2 tropospheric and stratospheric columns V04 (PROVISIONAL)

Nitrogen dioxide Level 2 (PROVISIONAL) 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 tropospheric and stratospheric nitrogen dioxide vertical columns, ancillary data used in airmass factor and stratospheric/tropospheric separation calculations, 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) stratospheric/tropospheric separation. These data reached provisional validation on December 9, 2024.
