1 RESUMO

 

O algoritmo SAFER (Simple Algorithm for Evapotranspiration Retrieving) tem sido largamente aplicado utilizando imagens obtidas dos satélites MODIS, Sentinel-2 e Landsat-5, 7 e 8. Essa nota científica apresenta a adaptação do algoritmo SAFER para imagens do sensor OLI/Landsat-9, ainda não publicada. Os valores de ETA estimados pelo método do SAFER apresentaram correlação de Pearson (r) estatisticamente significativo com os métodos FAO 56 e Embrapa (FAO 56, r = 0,96; Embrapa, r = 0,91).

ADAPTING THE SAFER ALGORITHM FOR LANDSAT 9 IMAGES

 

 

2 ABSTRACT

 

The SAFER algorithm (Simple Algorithm for Evapotranspiration Retrieving) has been widely applied to images obtained from the MODIS, Sentinel-2, and Landsat-5, 7, and 8 satellites. This scientific note presents the adaptation of the SAFER algorithm for images from the OLI/Landsat-9 sensor, which has not yet been published. ET A values estimated via the SAFER method presented a statistically significant Pearson correlation coefficient (r) with the FAO 56 and Embrapa methods (FAO 56, r = 0.96; Embrapa, r = 0.91).
