Tropospheric Formaldehyde

HCHO tropospheric column L3 data from SCIAMACHY, v2

SCIAMACHY level-3 gridded tropospheric HCHO column, version 2.

Monthly grids at spatial resolution of 1°x1°.

Based on the SCIAMACHY Level 2 Formaldehyde Total Column product created for the ESA CCI (European Space Agency Climate Change Initiative) Precursors for aerosols and ozone projet.

Compare to the QA4ECV product, the air mass factors have been reprocessed using an updated 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 columns, vertical columns and air mass factors, the level 3 data files contain several additional parameters and diagnostic information such as uncertainties, a priori profiles and averaging kernels.

Created for the ESA CCI ozone and aerosol precursors project.
