Optimal Integration of MODIS and MISR Albedo Products

Land surface albedo is an important parameter in describing the radiative properties of the earth\´s surface. However, due to the impact of persistent and transient cloud cover, temporal and seasonal snow, the albedo products have many gaps. And the different sensor products are inconsistent with each other as a result of different observing ways, different retrieving methods. So this paper aims at integrating MODIS and MISR albedo products to get better albedo products. First MODIS albedo products were converted to "Blue sky albedo" for comparation with validation data, while MISR directly provide this data. Then we examined the data loss and consistency of derive MODIS albedo data and MISR albedo data and found that blue sky albedo derieved form MODIS had a good consistent with ASRVN data except few proportion of it was underestimated and MISR albedo product overestimated it. After impletion of Optimal Interpolation Method(OI), the result is gapless and can improve the agreement with ASRVN albedo to some extent.
