Welcome! This synthesis of FORTRAN and Python is a globally applicable
weather generator inspired by the original WGEN weather generator of
[Richardson1981] and parameterized through a global dataset of [GHCN] and
[EECRA] data. A paper with the scientific documentation is in progress, the
technical documentation with more information is hosted on github.io.
When using GWGEN, we kindly ask you to provide a reference to the corresponding
paper published in Geoscientific Model Development:
Sommer, P. S. and Kaplan, J. O.: A globally calibrated scheme for
generating daily meteorology from monthly statistics: Global-WGEN (GWGEN)
v1.0, Geosci. Model Dev., 10, 3771-3791, DOI: 10.5194/gmd-10-3771-2017,
