EGR: Emissivity from atmosphere

In roilanhv/ROLi: Evaluate various downward longwave parametrizations

Description

Emissivity from atmosphere

Usage

EGR(data, func = "-", coef1 = 0.79, coef2 = 0.17, coef3 = 0.096,
  coef4 = 0.22, coef5 = 1, adjust = FALSE, forced = TRUE)

Arguments

data	a data frame with all atmospherics variables
func	a function for amount of cloud
coef1, coef2, coef3, coef4, coef5	Scheme coeficients
adjust	FALSE, TRUE if nonlinear least square adjusting wanted
forced	Forced adjust, default TRUE

Value

a vector with emissivity estimatives
