METRIC.Rn: Estimates Net Radiation as in METRIC Model

In ffuentesp7/METRICforR: Actual Evapotranspiration with Energy Balance models

Description

Estimates Net Radiation as in METRIC Model

Usage

METRIC.Rn(image.DN, WeatherStation, MTL, sat = "auto", thermalband,
  alb.coeff = "Tasumi", LAI.method = "metric2010", plain = TRUE, DEM, aoi)

Arguments

image.DN	raw imagen in digital counts to evaluate
WeatherStation	Weather Station data, can be a waterWeatherStation object
MTL	Landsat metadata file
sat	Landsat satellite version. "L7" or "L8"
thermalband	Landsat low gain thermalband
alb.coeff	coefficient to transform narrow to broad band albedo. See Details.
LAI.method	Method used to estimate LAI from spectral data. See Details.
plain	Logical. If TRUE surface is assumed plain
DEM	Digital Elevation Model of the study area. Not needed if plain = TRUE
aoi	SpatialPolygon object with limits of Area of interest
