As an initial step to understanding the physical processes impacting these uncertainties in satellite AOD retrievals, this study outlines a theoretical approach to estimate biases in the satellite aerosol retrieval algorithm affected by surface albedo and prescribed aerosol optical properties using a simplified radiative transfer model with a traditional error propagation approach. We expand the critical surface reflectance concept to obtain the critical surface albedo (CSA), critical single scattering albedo (CSSA), and critical asymmetry parameter (CAP). The top-of-atmosphere (TOA) reflectance is not sensitive to significant variability in aerosol loading (AOD) at the critical value; thus, the AOD cannot be determined. Results show that 5% bias in surface albedo (A), single scattering albedo (SSA), or asymmetry parameter (g) lead to large retrieved AOD errors, especially high under conditions when A, SSA, or g are close to their critical values. The results can be useful for future research related to improvements of satellite aerosol retrieval algorithms and provide a preliminary framework to analytically quantify AOD uncertainties from satellite retrievals.<\/jats:p>","DOI":"10.3390\/rs13030344","type":"journal-article","created":{"date-parts":[[2021,1,21]],"date-time":"2021-01-21T00:53:41Z","timestamp":1611190421000},"page":"344","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Theoretical Uncertainty Analysis of Satellite Retrieved Aerosol Optical Depth Associated with Surface Albedo and Aerosol Optical Properties"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5731-4268","authenticated-orcid":false,"given":"Jingting","family":"Huang","sequence":"first","affiliation":[{"name":"Department of Chemical Engineering, University of Utah, Salt Lake City, UT 84112, USA"},{"name":"Atmospheric Sciences Program, Department of Physics, University of Nevada-Reno, Reno, NV 89557, USA"}]},{"given":"William Patrick","family":"Arnott","sequence":"additional","affiliation":[{"name":"Atmospheric Sciences Program, Department of Physics, University of Nevada-Reno, Reno, NV 89557, USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2659-3214","authenticated-orcid":false,"given":"James C.","family":"Barnard","sequence":"additional","affiliation":[{"name":"Atmospheric Sciences Program, Department of Physics, University of Nevada-Reno, Reno, NV 89557, USA"}]},{"given":"Heather A.","family":"Holmes","sequence":"additional","affiliation":[{"name":"Department of Chemical Engineering, University of Utah, Salt Lake City, UT 84112, USA"},{"name":"Atmospheric Sciences Program, Department of Physics, University of Nevada-Reno, Reno, NV 89557, USA"}]}],"member":"1968","published-online":{"date-parts":[[2021,1,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1358","DOI":"10.1126\/science.156.3780.1358","article-title":"Climate Modification by Atmospheric Aerosols","volume":"156","author":"McCormick","year":"1967","journal-title":"Science"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"1001","DOI":"10.1175\/1520-0450(1969)008<1001:CTIOA>2.0.CO;2","article-title":"Climate: The Influence of Aerosols","volume":"8","author":"Charlson","year":"1969","journal-title":"J.
