calc_in_lwr: Calculate incoming Long-wave radiation

In aemon-j/gotmtools: Tools to work with GOTM input data and also process the output data

Calculate incoming Long-wave radiation

Description

Calculates incoming LWR using cloud cover, air temperature and relative humidity (or dewpoint temperature). Using formula from: http://www.seao2.info/_TMP/longwave.pdf

Usage

calc_in_lwr(cc, airt, relh = NULL, dewt = NULL)

Arguments

cc	vector; cloud cover values (Fraction [0-1])
airt	vector; air temperature values (Celsius)
relh	vector; relative humidity values (% [0-100]). Used to calculate dewpoint temperaure if that is not supplied. Defaults to NULL.
dewt	vector; dewpoint temperature values (Celsius). Can be used instead of relative humidity, otherise it is calculated from relative humidity and air temperature. Defaults to NULL

Value

vector of incoming long-wave radiation values

Examples

 met_file <- system.file('extdata/met_file.dat', package = 'GOTMr')
 met <- read.delim(met_file)
 lwr_in <- calc_in_lwr(cc = met$CC, airt = met$AirT, dewt = met$DewT)
 plot(lwr_in)
