Several minor revisions are necessary before the manuscript can be published.
1. There are several mistakes in the descriptions of NO2 products in Table 1. Taking POMINO as an example, please refer to Table 1 of Lin et al. (2015, ACP) for correct descriptions.
2. Treatment of clouds and use of look-up table are both key sources of errors in satellite products. Please specify the cloud dataset and whether a LUT is used in these products.
3. Page 6, Line 17 -- In this study, surface albedo dataset is used rather than surface reflection, which is a limitation. There are many places in the text where “surface reflectivity” should be changed to “surface albedo”, the quantity actually used in this study. Also, in this study, aerosol optical depth is not used explicitly to derive the AMF; please revise Line 17. |
