A joint product by: BIRA-IASB, KNMI, MPI-C, University of Bremen, and Wageningen University
The QA4ECV HCHO Essential Climate Variable precursor product contains harmonized HCHO column densities for the period 1996-2015. Specifically, the provided product is the tropospheric vertical column density.
The HCHO ECV data provides geophysical information for each and every ground pixel observed by GOME, SCIAMACHY, OMI, and GOME-2A, without the additional binning, averaging or gridding typically applied for Level 3 data. In addition to vertical HCHO column densities, the product contains intermediate results, such as the result of the spectral fit, fitting diagnostics, the averaging kernel, cloud information, and algorithm and product error estimates.
