calc_swr: Calculate SWR using calculation within GOTM

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

Description

Calculates incoming SWR using cloud cover, time, latitude and longitude. Calculations taken from the GOTM code. See https://github.com/gotm-model/code Note: For GOTM all inputs have to be in UTC so be sure to switch back to local timezone if working with subdaily data.

Usage

calc_swr(time, lat, lon, cloud, daily2hour = F)

Arguments

time	vector; In POSIXct format
lat	numeric; Latitude in decimal degrees
lon	numeric; Longitude in decimal degrees
cloud	vector; Cloud cover values [0-1] which correspond to the times supplied
daily2hour	logical; Indicate whether you are converting daily cloud cover data to hourly SWR or hourly cloud cover. Default = FALSE

Value

If daily2hour = FALSE, then a vector of SWR values are returned corresponding to input time vector. If TRUE, a data.frame with the DateTime and SWR are returned.
