\r
Compare to the operational product, the 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.\r
\r
In addition to the main product results, such as HCHO slant column, vertical column and air mass factor, the level 2 data files contain several additional parameters and diagnostic information.\r
\r
Created for the ESA CCI ozone and aerosol precursors project."""@en ;
