Satellite Retrieval of Surface Evapotranspiration with Nonparametric Approach: Accuracy Assessment over a Semiarid Region

Table 4

Average of input parameters derived by MODIS products at the six sites, including land surface temperature (), near-surface air temperature (), land surface emissivity (LSE), near-surface pressure (), dew point temperature (), albedo, and NDVI. The retrieved net radiation (), soil heat flux (), and latent heat flux (LE) are also shown.
