Here, we employ satellite HCHO retrievals from the Ozone Monitoring Instrument (OMI)\u2014the NASA retrieval developed by the Smithsonian Astrophysical Observatory (SAO), and the European Union Quality Assurance for Essential Climate Variables (QA4ECV) retrieval\u2014to evaluate three CMAQ configurations, spanning the summers of 2011 and 2016, with differing biogenic emissions inputs and chemical mechanisms. These CMAQ configurations capture the general spatial and temporal behavior of both satellite retrievals, but underestimate column HCHO, particularly in the western U.S. In the southeastern U.S., the comparison with OMI HCHO highlights differences in modeled meteorology and biogenic emissions even with differences in satellite retrievals. All CMAQ configurations show low daily correlations with OMI HCHO (<jats:italic>r<\/jats:italic>\u00a0=\u00a00.26\u20130.38), however, we find higher monthly correlations (<jats:italic>r<\/jats:italic>\u00a0=\u00a00.52\u20130.73), and the models correlate best with the OMI\u2010QA4ECV product. Compared to surface observations, we find improved agreement over a 24\u2010h period compared to afternoon\u2010only, suggesting daily HCHO amounts are captured with more accuracy than afternoon amounts. This work highlights the potential for synergistic improvements in modeling and satellite retrievals to support near\u2010surface HCHO estimates for the NATA and other applications.<\/jats:p>","DOI":"10.1029\/2020jd032881","type":"journal-article","created":{"date-parts":[[2020,12,25]],"date-time":"2020-12-25T08:18:21Z","timestamp":1608884301000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":24,"title":["Satellite Formaldehyde to Support Model Evaluation"],"prefix":"10.1029","volume":"126","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0646-7926","authenticated-orcid":false,"given":"Monica","family":"Harkey","sequence":"first","affiliation":[{"name":"Nelson Institute Center for Sustainability and the Global Environment (SAGE) University of Wisconsin\u2010Madison  Madison WI USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8488-408X","authenticated-orcid":false,"given":"Tracey","family":"Holloway","sequence":"additional","affiliation":[{"name":"Nelson Institute Center for Sustainability and the Global Environment (SAGE) University of Wisconsin\u2010Madison  Madison WI USA"},{"name":"Department of Atmospheric &amp;
