Code 8.9: Zenith Atmospheric Opacity and Transmissivity—Clear Atmosphere

Code Name: ZenithAtmosOpacity_ClearAtmos.m

Description: Using a Standard Atmosphere model, code computes opacity of the entire atmosphere under clear-sky conditions, along the zenith, 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)

Output Products:

  τ0:    Zenith opacity (Np)
  ϒ (0,∞):    Transmissivity (unitless)

Book Reference: Section 8-3
