Abstract:The TOA narrow to broadband conversion model,bidirectional reflectance model,and atmospheric correction model are the necessary models for retrieving surface albedos with reflectance from NOAA AVHRR. Based on the models and NOAA 18 AVHRR 1B data, the clear sky surface albedos in the area of 10°to 60°N and 65°to 145°E with a resolution of 001°×001°lat/lon from January 2006 to December 2010 are calculated. A 15 day data combination technology is used to produce the albedo products in a 15 day cycle. Comparison is conducted between the two year products and MODIS measurements. The RMSs are 0028 to 0074, correlation coefficients are 076 to 093 The larger errors occurred in winter are caused by the different combination technologies adopted by the two products. The daily mean surface albedos from 21 first class surface meteorological radiation stations over China are selected and compared with the produced data.The results show: RMS is 0053, and the correlation coefficient is 08808 The impacts of Clouds and aerosols are the main error sources of surface albedo retrieval from satellite.
