GWGEN v1.0.2: A global weather generator for daily data

Philipp S. Sommer; Jed O. Kaplan

This synthesis of FORTRAN and Python is a globally applicable
weather generator inspired by the original WGEN weather generator of
Richardson, 1981 and parameterized through a global dataset of GHCN (Menne et al., 2012) and
EECRA (Hahn and Warren, 1999) data.
The technical documentation can be seen under https://arve-research.github.io/gwgen/

  • gwgen-1.0.2.zip: The full source files for FORTRAN and Python including the data for unittests
  • gwgen-1.0.2-no-test-data.zip: The full source files without test data
  • gwgen_docs_v1.0.2.zip:  The documentation as static html
  • gwgen-conda-1.0.2-Linux-x86_64_2.7.sh: A bash installer for Linux with python 2.7
  • gwgen-conda-1.0.2-Linux-x86_64_3.6.sh: A bash installer for Linux with python 3.6
  • gwgen-conda-1.0.2-MacOSX-x86_64_2.7.sh: A bash installer for MacOSX with python 2.7
  • gwgen-conda-1.0.2-MacOSX-x86_64_3.6.sh: A bash installer for MacOSX with python 3.6

 

Installation from source

To install the source files in gwgen-1.0.2.zip, you need python, numpy, matplotlib, sqlalchemy, statsmodels, scipy and pandas to be preinstalled. Then you can run

python setup.py install

to install the python files

Installation using the bash installer

The bash installers listed above contain a self-contained conda environment that includes all dependencies for GWGEN and GWGEN itself. You need to install a FORTRAN compiler, e.g. gfortran, by yourself.

Just run

bash gwgen-conda-1.0.2-Linux-x86_64_2.7.sh

and follow the instructions.
