tglob_sphere

Description

Calculate the globe temperature in degC. The code is based on the work James C. Liljegren Decision and Information Sciences Division Argonne National Laboratory.

Usage

tglob_sphere(
  t,
  rh,
  wind,
  solar,
  zenith = 0,
  pair = 1010,
  alb_sfc = 0.4,
  fdir = 0.8,
  diam = 0.05,
  maxair = 10,
  minair = 2,
  prec = 0.01
)

Arguments
