Simple Air Temperature Estimation Method from MODIS Satellite Images on a Regional Scale

Agricultural studies on a regional scale about water balance and evapotranspiration estimation, among others, require estimating air temperature (Ta) spatial variation since the generally low density of weather stations does not allow obtaining such data for a specific area. The aim of this study wa...
