Radiative properties of the marine boundary layer that can be derived from current and planned satellite polarimeters. DOI: https://doi.org/10.1525/elementa.331.t5

MBL atmospheric characteristicCurrent satellite polarimeters: PARASOL/POLDERPotential future polarimeters: 3MI, multi-angular polarimeter on PACE mission

 
Microphysical aerosol properties Complex refractive index, size distribution, aerosol nonsphericity, aerosol concentration Increased retrieval accuracy (for polarimetric uncertainty <0.5%), increased spatial coverage and resolution 
Optical aerosol properties Aerosol optical depth (AOD), single scattering albedo (SSA), Angström exponent, aerosol extinction profile, aerosol type, aerosol backscatter Increased retrieval accuracy (for polarimetric uncertainty <0.5%), increased spatial coverage and resolution 
Aerosol vertical profile Estimated accuracy of 1–2 km limited by sensitivity to aerosol height distribution Better accuracy due to addition of polarisation channels in the blue and UV wavelength regime (and reduction in polarimetric uncertainty) 
Cloud microphysics Cloud droplet size distribution, cloud phase, ice crystal shape, cloud top height and thickness Increased accuracy (for polarimetric uncertainty <0.5%), increased spatial coverage and resolution
