IPRT polarized radiative transfer model intercomparison
General conventions:
For all cases normalized radiances are compared (i.e. Stokes vector components devided by the extraterrestrial irradiance).
The viewing azimuth angle is defined clockwise
The sun position is the position of the sun in the sky defined by solar zenith angle sza and solar azimuth angle saa. Note that the direction vector (vza, vaa) is then opposite to the solar beam travel direction (vaa = saa indicates that the sensor looks into the direction of the sun, vaa-saa = 180° means that the sun is in the back of the sensor)
The output format is ascii, details are provided for the individual test cases
In order to check model definitions of signs of the Stokes vector and azimuth angles, you should first run only case A1.
