Code 16.1: The CMOD5 Geophysical Model Function

Code Name: CMOD5.m

Description: Code computes C-band vv σ0 for a specified incidence angle, radar azimuth angle, wind direction, and wind speed according to the CMOD5 geophysical model function.

Input Variables:

  θ:    Incidence angle [15 ≤ θ ≤ 60] (degrees)
  ϕradar:    Radar illumination azimuth angle relative to north (deg)
  ϕwind:    Wind direction relative to north (meteorological convention, deg)
  U:    Wind speed [0≤ U≤60] (m/s)

Output Products:

        σ0:    vv normalized radar cross-section (unitless)
