Simple sunglint computation based on Cox & Munk model. For more details on the statistics of the wave slopes (i.e., Probability Distribution Function), please refer to Munk 2009.
These instructions will get you a copy of the project up and running on your local machine for development and testing purposes.
What things you need to install the software and how to install them
python3 -m pip install --user --upgrade setuptools
First, clone the repository and execute the following command in the local copy:
python3 setup.py install
This will install the package into the system's Python path. If you have not the administrator rights, you can install the package as follows:
python3 setup.py install --user
If another destination directory is preferred, it can be set by
python3 setup.py install --prefix=<where-to-install>
This installation is supposed to download
and compile all the associated packages as well as prepare the executables coxmunk.
If the installation is successful, you should have:
$ coxmunk
Usage:
coxmunk <sza> <wind_speed> [--stats <stats>] [--wind_azi <wind_azi>]
coxmunk -h | --help
coxmunk -v | --version
Examples for Cox & Munk model with Bréon & Henriot statitics for:
- solar vieving angle = 39°
- wind azimuth from Sun = 75°
- wind speed = 0.2, 7.2, 14.2 m.s-1
$ coxmunk 39 0.2 --stats bh2006 --wind_azi 75 --figname illustration/coxmunk_fig_39_0.2_bh2006_75.png
$ coxmunk 39 7.2 --stats bh2006 --wind_azi 75
$ coxmunk 39 14.2 --stats bh2006 --wind_azi 75
With the option --slope you can also check
the values of wave slopes upwind and crosswind,
the first term of the Fresnel matrix and the probability distribution function:
$ coxmunk 20 5 --stats bh2006 --wind_azi 60 --slope
