An evaluation of MODIS global evapotranspiration product (MOD16A2) as terrestrial evapotranspiration in East Java - Indonesia
MetadataShow full item record
MODIS global evapotranspiration product (MOD16A2) was used widely in the world as terrestrial evapotranspiration. This research aimed to evaluate the performance of MODIS global evapotranspiration products as terrestrial evapotranspiration in East Java – Indonesia. A total of 5 climatological station data and 30 scenes of MODIS global evapotranspiration image recording 2015 – 2018 were used for analysis. Research shows that MODIS global evapotranspiration overestimates compared with climate data analysis with a lower deviation. Generally,MODIS global evapotranspiration can estimate evapotranspiration with 75% accuracy compared with climate data analysis. Besides MODIS global evapotranspiration in East Java has mean error (ME) 0.64 mm/day, mean absolute error (MAE) 0.92 mm/day, root mean square error (RMSE) 1.10 mm/day, relative bias (RBIAS) 0.25, mean bias factor (MBIAS) 1.04, and correlation coefficient (CC) 0.25.
