CCI+P Glyoxal tropospheric column L3 data from GOME-2B

Glyoxal (CHOCHO) tropospheric vertical columns retrieved from the GOME-2/MetOp-B instrument as part of the ESA CCI precursors for aerosols and ozone project.

This dataset provides a set of L3 gridded glyoxal vertical columns obtained from GOME-2/MetOp-B for the period of 2013 until 2023, with monthly grids at a resolution of 0.25°.
The retrieval is based on the TROPOMI/S5P retrieval method developed within the GLYRETRO and S5P-PAL projects, but features more precise air mass factor calculations using a directional surface albedo database based on GOME-2 observations, and a set of daily a priori glyoxal profile shapes obtained using the MAGRITTE chemical transport model.
