Rain - Lucile Gaultier - 2019-03-20

It is now possible to generate random rain cells in selected areas.
Some scenes are available for each hour in a python file (.pyo).
You can download these files from the ftp:
ftp.odl.bzh/odl/skim/rain_samples.tar.xz

The simulator adds the rain information in the l2b skim file and flags data in the ur_obs variables that contain rain over the defined rain_threshold.
More sophisticated implementation will follow to account for the attenuation in sigma0 in the presence of very light rain and clouds.

The following parameters are to be added in the parameter file:
Code:
# ------ Rain error (True to compute it):
rain = True
# ------ Rain file containing scenarii (python file):
rain_file = os.path.join(dir_setup, 'rain_eq_atl.pyo')
# ------ Threshold to flag data:
rain_threshold = 0.1
