A global 0.05 ◦ maximum albedo dataset of snow-covered land based on MODIS observations

[1] A new global 0.05 maximum albedo for snow-covered land is developed from BRDF/Albedo, reflectance and land cover measured from the MODIS sensor on board the Terra and Aqua satellites. The dataset is similar to previous maximum snow albedo datasets, but is available at higher resolution. The data...

Description
Summary:[1] A new global 0.05 maximum albedo for snow-covered land is developed from BRDF/Albedo, reflectance and land cover measured from the MODIS sensor on board the Terra and Aqua satellites. The dataset is similar to previous maximum snow albedo datasets, but is available at higher resolution. The dataset displays: (1) high albedo at very high latitudes with tundra and open shrub land cover; (2) a local minimum (0.35) in zonally-averaged albedo at 56–60N due to boreal forest cover; and (3) a local maximum (0.70) in zonally-averaged albedo at 42–45N due to crop and grassland. The dataset is tested in the Noah land model at 0.125 resolution as used in the North American Land Data Assimilation System. Compared with the original data, the new dataset increases the spatial heterogeneity in the Noah model during winter and produces surface energy component differences of 10 W/m2 during the snowmelt period.
