We present an optimal estimation based retrieval framework, the Microphysical Aerosol Properties fromPolarimetry (MAPP) algorithm, designed for simultaneous retrieval of aerosol microphysical propertiesand ocean color bio-optical parameters using multi-angular total and polarized radiances. Polarimetricmeasurements from the airborne NASA Research Scanning Polarimeter (RSP) were inverted by MAPP to produce atmosphere and ocean products. The RSP MAPP results are compared with co-incident lidarmeasurements made by the NASA High Spectral Resolution Lidar HSRL-1 and HSRL-2 instruments.Comparisons are made of the aerosol optical depth (AOD) at 355 and 532 nm, lidar column-averaged measurementsof the aerosol lidar ratio and Ångstrøm exponent, and lidar ocean measurements of the particulatehemispherical backscatter coefficient and the diffuse attenuation coefficient. The measurements werecollected during the 2012 Two-Column Aerosol Project (TCAP) campaign and the 2014 Ship-Aircraft BioOpticalResearch (SABOR) campaign. For the SABOR campaign, 73% RSP MAPP retrievals fall within ±0.04 AOD at 532 nm as measured by HSRL-1, with an R value of 0.933 and root-mean-square deviationof 0.0372. For the TCAP campaign, 53% of RSP MAPP retrievals are within 0.04 AOD as measured byHSRL-2, with an R value of 0.927 and root-mean-square deviation of 0.0673. Comparisons with HSRL-2AOD at 355 nm during TCAP result in an R value of 0.959 and a root-mean-square deviation of also 0.0694.The RSP retrievals using the MAPP optimal estimation framework represent a key milestone on the pathto a combined lidar+polarimeter retrieval using both HSRL and RSP measurements.
