radiation_l8t function

Energy balance using Landsat-8 images (including thermal bands) with single agrometeorological data.

radiation_l8t(doy, RG, Ta, ET0, a, b)

Arguments

• doy: is the Day of Year (DOY)
• RG: is the global solar radiation
• Ta: is the average air temperature
• ET0: is the reference evapotranspiration
• a: is one of the regression coefficients of SAFER algorithm
• b: is one of the regression coefficients of SAFER algorithm

Returns

It returns in raster format (.tif) the Surface Albedo at 24h scale ("Alb_24"), NDVI, Surface Temperature ("LST"), Crop Coefficient ("kc"), Actual Evapotranspiration (evapo), latent heat flux "LE_MJ"), net radiation ("Rn_MJ"), ground heat flux ("G_MJ") and the sensible heat flux ("H_MJ").
