1. Download the zip files (artdeco.zip and data_artdeco.zip) to your working directory and unzip $ unzip artdeco.zip $ unzip data_artdeco.zip 2. Go to the directory 'artdeco/fortran/', type: $ cd artdeco/fortran/ Create some directories $ mkdir f2py $ mkdir mod $ mkdir obj $ mkdir out 3. You can now compile the code from Artdeco/fortran/src $ cd src $ make To do this, you need a Fortran 90/95 compiler and f2py (Fortran-Python interface tools provided with the numpy library). You need Python 3. 4. Go back to the root directory, and run the example code $ cd ../../../ Change the paths at the top of the file, for example: # These directories must be changed according to your installation dir_data = "your_working_directory/data_artdeco/" dir_artdeco = "your_working_directory/artdeco/fortran/" dir_pyartdeco = "your_working_directory/pyartdeco/" "your_working_directory" is the directory where you save the artedco and data_artdeco zip files. $ python example_use.py 5. Once the code is successively run, the plots of simulated TOA and BOA flux, TOA upwelling radiance, and TOA reflectance are saved in your working directory.
