Code Name: TSKY_ClearAtmos.m
Description: Using a Standard Atmosphere model, code computes the brightness temperature of the atmosphere as would be observed by a ground-based upward-looking radiometer, under clear-sky conditions, along direction Θ relative to the zenith (0 < Θ < 80 °), from sea-surface height z1 = 0 to z2 = 32 km, at any frequency 0 < f < 1000 GHz.
Input Variables:
T0: | Sea-surface temperature (°C) |
P0: | Sea-surface total barometric pressure (mbar) |
ρ0: | Sea-surface total water vapor density (g/m3) |
f: | Frequency (GHz) |
Θ: | Zenith angle (degrees) |
Output Products:
TSKY: | Sky radiometric temperature (K) |
Book Reference: Section 8-4 and Eqs. (8.23) and (8.24)
