This dataset provides gridded HCHO tropospheric column densities of monthly 0.125°x0.125° resolution grids from May 2018 to December 2024. The L3 product is based on the Level 2 HCHO product created for the Precursors_cci project. Compared to the operational TROPOMI product, the air mass factors have been reprocessed using an update albedo climatology, and the CAMS (Copernicus Atmosphere Monitoring Service) 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. The version number is 2.0. Data are available in NetCDF format. https://doi.org/10.18758/y591kda5 The European Space Agency (ESA) Precursors for Aerosol and Ozone Climate Change Initiative (Precursors CCI) project is part of ESA's Climate Change Initiative (CCI) to produce long term datasets of Essential Climate Variables derived from global satellite data (https://climate.esa.int/en/projects/precursors-for-aerosols-and-ozone/).
