Description

Calculates clear sky radiation

Usage

clearskyrad(
  tme,
  lat,
  long,
  h = 0.00697,
  tc = 15,
  pk = 101.3,
  G = 2.78,
  Ie = 1352.778,
  merid = 0,
  dst = 0
)

Arguments

tme	POSIXlt object of times in UTC.
lat	latitude of the location for which the solar azimuth is required (decimal degrees, -ve south of the equator).
long	longitude of the location for which the solar azimuth is required (decimal degrees, -ve west of Greenwich meridian).
h	optional specific humidities (kg kg{-1} ).
tc	optional temperatures (ºC).
pk	optional pressure (kPa).
G	optional value describing he moisture profile in the atmosphere (per Smith 1966).
Ie	an optional single value for extra-terrestrail radiation to permit adjustment for sun-earth distances
merid	optional value representing the longitude (decimal degrees) of the local time zone meridian (0 for GMT). Default is round(long / 15, 0) * 15
dst	optional value representing the time difference from the timezone meridian (hours, e.g. +1 for BST if merid = 0).

Value

expected clear-sky radioation (W/m^2.
