Using the MODIS land surface temperature product for mapping permafrost: an application to northern Québec and Labrador, Canada
Abstract The Land Surface Temperature (LST) products of the Moderate Resolution Imaging Spectroradiometers (MODIS) aboard NASA's Terra and Aqua satellites were used to develop maps of annual near‐surface temperatures for comparison with the spatial distribution of permafrost and boundaries of t...
