Abstract

The remote sensing became an important tool in agriculture, mainly in the obtaining of data on the weather variables, like the range of evapotranspiration averages. This way, this work aimed to estimate the evapotranspiration in a regional scale in the Paulista Northwest and it’s temporal and spacial distribution through the use of SAFER (Simple Algorithm for Evapotranspiration Retrieving) algorithm and images from the satellites Landsat 5 and Landsat 8 in 2010, 2017 and 2018. The SAFER algorithm showed effective for the estimation of evapotranspiration in large scale and this methodology can be applied in further studies to monitor agricultural and climatological indicators of the region. The medium values of evapotranspiration ranged from 0.5 and 2.5 mm day-1, being the highest values recorded in the irrigated areas. Regionally, the highest averages were obtained in the rainy season of the region, with values close to 2 mm day-1.
