Long term validation of moderate resolution and multi-angle remote sensing snow albedo over Greenland

Moderate Resolution Imaging Spectroradiometer (MODIS) and Multi-angle Imaging SpectroRadiometer (MISR) are widely used remote sensors. Their albedo products over snow are compared with in situ data from the Greenland Climate Network (GC-Net). MODIS can catch the long term albedo change over Greenland. Considering several uncertainties in origin, MODIS and MISR albedo products agree with in situ albedo within the limits of accuracy and temporal representativeness.
