Multisensor Machine Learning to Retrieve High Spatiotemporal Resolution Land Surface Temperature by Kate Duffy, Thomas J. Vandal, Ramakrishna R. Nemani

“…While multiple satellite types provide data to monitor surface temperature, geostationary (GEO) sensors provide near-continuous, continental-scale observations which can better capture the diurnal variability of land surface temperature (LST) than intermittent observations from low-earth orbit (LEO) sensors. However, standard products from GEO satellites are available at coarsened spatial and temporal resolutions compared to the native sensor resolution. …”
