The Global LAnd Surface Satellite albedo product was produced by using MODIS data product of 1km Surface reflectance (MOD/MYD09GA), Angular Bin inversion algorithm and statistics-based Temporal Filter algorithm based on statistical knowledge.This data set is in the GLASS global products using the two tiles covering the heihe river basin (h25v04, h25v05), after a Mosaic, projection transformation, and cutting the heihe river basin 1 km resolution epicontinental black empty albedo (black - sky albedo) and white empty albedo (white - sky albedo) data sets, including both Albers and UTM projection method, are raw format, space vector boundary of heihe river basin is the scope of the rectangle, temporal resolution for eight days.

The Global LAnd Surface Satellite albedo product was produced by using MODIS data product of 1km Surface reflectance (MOD/MYD09GA), Angular Bin inversion algorithm and statistics-based Temporal Filter algorithm based on statistical knowledge.In this data set, two tiles (h25v04 and h25v05) covering the black river basin were selected from GLASS global products. After Mosaic, projection conversion and cutting, the black sky albedo and white sky albedo data sets with 1km resolution of the black river basin were obtained, including SIN and UTM projection methods.The data set of SIN projection is in HDF format, with a large coverage range (about 1200*2400 square kilometers) and a temporal resolution of 1 day.The UTM projection data set is in raw format, cut according to the vector boundary of black river, and the temporal resolution is 8 days.

Used in environment and mitigation of small satellite constellation 30 m image of CCD sensor, after scaling, geometric correction and based on the Angle of the top of the atmosphere apparent reflectance grid regression (presents Bin) inversion algorithm inversion of surface shortwave albedo, choose the image Mosaic of cloud cover at least a month again become full of heihe river basin albedo distribution, projection method for UTM projection, the spatial resolution of 30 meters, time and frequency of 1 per month.The data file contains two bands, namely the black-sky albedo of local noon and the white-sky albedo corresponding to the solar Angle at the local noon, which are stored in the form of a short integer with a scaling factor of 0.0001.
