Validation of the Updated SAO OMI Formaldehyde Retrieval
Abstract
The new SAO OMI formaldehyde retrieval, version v3.0.2 publicly released in June 2014, introduces major changes with respect to the previous version of the product. These changes include optimization of fitting window and fitting parameters, update of reference cross sections, reference sector normalization to the Pacific Ocean and a new air mass factor calculation. In this context it is necessary to assess the accuracy of the new product and perform a validation exercise. We compare the new data with other satellite retrievals from OMI, GOME-2 and SCIAMACHY performed by the Belgian Institute for Space Aeronomy, with in situ airborne measurements recorded using a Difference Frequency Generation Absorption Spectrometer (DFGAS) instrument, with aircraft passive remote sensing retrievals from the ACAM and GeoTASO instruments recorded during the DISCOVER-AQ field campaigns in Maryland and Texas and with ground-based DOAS measurements.
