cal_extraterrestrialRadiation_for_daily R Documentation
Calculating extraterrestrial radiation for daily periods
Description
The extraterrestrial radiation, Ra, for each day of the year and
for different latitudes can be estimated from the solar constant, the
solar declination and the time of the year.
Usage
cal_extraterrestrialRadiation_for_daily(J, lat)
Arguments
J
is the number of the day in the year between 1 (1 January) and 365
or 366 (31 December).
lat
latitude (Radian), positive for the northern hemisphere and
negative for the southern hemisphere.
Value
A vector for extraterrestrial radiation for daily(MJ m-2 day-1)
