evapo_l8

Actual evapotranspiration (ETa) using Landsat-8 images with single agrometeorological data.

Spatial modeling of energy balance and actual
evapotranspiration using satellite images and meteorological data.
Options of satellite are: Landsat-8 (with and without thermal bands),
Sentinel-2 and MODIS. Respectively spatial resolutions are 30, 100,
10 and 250 meters. User can use data from a single meteorological
station or a grid of meteorological stations (using any spatial
interpolation method). Silva, Teixeira, and Manzione (2019) <doi:10.1016/j.envsoft.2019.104497>.
