    Paruelo et al. (2001) [1] and Alcaraz-Segura et al. (2006, 2013) [2] [3] refined the EFT concept and proposed a remote-sensing based methodology to derive them. Since then, several authors have implemented the idea under the same or similar approaches using NOAA-AVHRR, MODIS and Landsat archives.
