CCI+P Glyoxal tropospheric column L3 data from TROPOMI

Glyoxal (CHOCHO) tropospheric vertical columns retrieved from the TROPOMI/S5p 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 TROPOMI/S5P, for the period of May 2018 until December 2023, at resolution of 0.5° (daily grids) or 0.125° (monthly grids) . The retrieval is based on the method developed for the GLYRETRO and S5P-PAL projects, but features an improved destriping and background correction method, as well as more precise air mass factor calculations using a high-resolution surface albedo database based on TROPOMI observations, and a set of daily a priori glyoxal profile shapes obtained using the MAGRITTE chemical transport model.
