From 2004 to 2013, PARASOL had offered multi-angle (up to 16) polarized and intensity measurements in nine bands. In the paper, based on MISR’s multi-angle algorithm, aerosol is retrieved from multi-angle intensity measurements of PARASOL. For the application of MISR’s multi-angle algorithm, the atmospheric correction of PARASOL intensity data was done in Beijing area. It is shown that in green, red and near infrared bands, the normalized reflectance are close, but that in blue band are not stable. So, in our algorithm, the measurements in green, red and near infrared bands are selected to retrieve aerosol. We retrieved aerosol as follow: 1) For the aerosol mixed with fine and coarse particles, we revise the surface reflectance from PARASOL multi-angle intensity data in the grid of aerosol optical depth (AOD) from 0 to 1.8; 2) with the variance between normalized reflectance and its band average, an overall residual for each AOD is worked out; 3) the minimum residual provides the values for AOD. Then, we retrieved aerosol over Beijing area in 2009. The correlation coefficient between our retrieved and AERONET Beijing measured AOD is more than 0.7, and AODs from our algorithm is obviously smaller than that from ground-based measurements.
