False-color (Bands 7-2-1) corrected reflectance image of snow covering Iceland. The image was acquired on 26 April 2020 by the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument, aboard the Aqua satellite.
In this false-color image, the 7-2-1 band combination can be used to distinguish snow and ice from clouds. Snow appears in cyan and clouds are white/white-light cyan. You can also turn on the Snow Cover (Normalized Difference Snow Index) layer to evaluate how much snow is on the ground.
