Aerosol single-scattering albedo and asymmetry parameter from MFRSR observations during the ARM Aerosol IOP 2003
International audience Multi-filter Rotating Shadowband Radiometers (MFRSRs) provide routine measurements of the aerosol optical depth (?) at six wavelengths (0.415, 0.5, 0.615, 0.673, 0.870 and 0.94 ?m). The single-scattering albedo (? 0 ) is typically estimated from the MFRSR measurements by assum...
