Abstract. Currently, the validation of MODIS and Himawari-8 aerosol products mostly focuses on AOD, but the validation of their fine mode aerosol data is limited. In this paper, 22 AERONET sites in Asia from 2015 to 2016 were selected to validate the MODIS and the Himawari-8 fine aerosol product. In the validation of all the observation data the accuracy of the MODIS fAOD (RMSE is 0.399 and MAE is 0.280) is higher than the Himawari-8 fAOD (RMSE is 0.433 and MAE is 0.293). For the validation of FMF, the accuracy of MODIS FMF (RMSE is 0.520 and MAE is 0.433) is higher than the Himawari-8 FMF (RMSE is 0.535 and MAE is 0.438) as well. This research also presents the validation in different AERONET locations. From the all validation results, MODIS retrievals of fine mode aerosol products are better than that of Himawari-8’s. However, in comparison with AERONET observations, both MODIS and Himawari-8 retrievals are underestimated. Therefore, we need to further develop the fine mode aerosol retrieval method to obtain more accurate fine mode aerosol product by satellite.
