CCI+P HCHO tropospheric column L3 data from GOME-2, v2

GOME-2 A/B/C level-3 gridded tropospheric HCHO column, version 2.

Monthly grids at spatial resolution of 0.25°x0.25°.

Based on the GOME-2 A/B/C Level 2 Formaldehyde Total Column product created for the EUMETSAT AC SAF project (prototype product).

Compare to the AC SAF GDP products, the slant columns have been reprocessed using DOAS settings harmonized with the operational TROPOMI product. Air mass factors have been reprocessed using an update aldebo climatology, and the CAMS Reanalysis Model for the a priori vertical profiles. The background correction and the quality values have also been updated.

In addition to the main product results, such as HCHO slant column, vertical column and air mass factor, the level 3 data files contain several additional parameters and diagnostic information such as uncertainties, a priori profiles and averaging kernels.

Created for the AC SAF CDOP4 project.
