Download at Earth Explorer Landsat 8 scene (LS8 - OLI/TIRS)
Reproject LS8 images for the coordinate system of interest
mkdir rep && for i in *.TIF ; do gdalwarp -s_srs EPSG:32624 -t_srs EPSG:31984 -of GTiff $i rep/$i; done
Remove null values (black borders) of LS8 images
mkdir nodata && for i in *.TIF; do gdal_translate -a_nodata 0 $i nodata/$i; done
Download at Earth Explorer the Digital Elevation Model (DEM) from ASTER (remember to choose the same region of LS8 scene)
It is necessary to reproject the DEM for the coordinate system of interest and rename to MDT_Sebal.TIF
gdalwarp -s_srs EPSG:32624 -t_srs EPSG:31984 -of GTiff ASTGTM2_S23W048.tif MDT_Sebal.TIF
Launch a GRASS-GIS 7.X session
Place Sebal70.py script in the directory where LS8 images are located
In Terminal Linux or Command Prompt Windows opened by GRASS, navigate to the directory where the Sebal70.py and LS8 images are located
python Sebal70.py
