A New Satellite-Based Dataset for Research and Operational Monitoring of Land Surface Processes
The Cooling Efficiency Factor Index (CEFI) is an observational dataset that quantifies the land surface energy dissipation through turbulent and ecohydrological processes. It is defined based on diurnal variations in apparent heat capacity, a land surface property derived from geostationary satellite data acquired by the EUMETSAT’s Meteosat Second Generation (MSG) program. The dataset is available from 2005 onward and covers Europe, Africa, and parts of West Asia and South America at a spatial resolution of 5 km. The spatial variability of the CEFI reflects differences in land surface properties, including surface roughness, vegetation cover, and water availability. Its temporal variability primarily serves as a proxy for drought stress events over vegetated regions and for wind speed anomalies over bare ground.
