Comparing Landsat-7 ETM+ and ASTER Imageries to estimate daily evapotranspiration within a Mediterranean vineyard watershed Montes, C. /Jacob, Frédéric ZONE MEDITERRANEENNE Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) daily evapotranspiration (ET) Landsat-7 Enhanced Thematic Mapper Plus (ETM plus ) simplified surface energy balance index (S-SEBI) solar and thermal infrared remote sensing vineyard landscape We compared the capabilities of Landsat-7 Enhanced Thematic Mapper Plus (ETM+) and Advanced Space-borne Thermal Emission and Reflection Radiometer (ASTER) imageries for mapping daily evapotranspiration (ET) within a Mediterranean vineyard watershed. We used Landsat and ASTER data simultaneously collected on four dates in 2007 and 2008, along with the simplified surface energy balance index (S-SEBI) model. We used previously ground-validated good quality ASTER estimates as reference, and we analyzed the differences with Landsat retrievals in light of the instrumental factors and methodology. Although Landsat and ASTER retrievals of S-SEBI inputs were different, estimates of daily ET from the two imageries were similar. This is ascribed to the S-SEBI spatial differencing in temperature, and opens the path for using historical Landsat time series over vineyards. 2017 text https://www.documentation.ird.fr/hor/fdi:010069357 fdi:010069357 Montes C., Jacob Frédéric.
