GloFAS v3.3

The following is a description of GloFAS v3.3. For an overview of other GloFAS releases, please see: GloFAS versioning system

Summary

GloFAS version 3.3 is associated with a change in ECMWF IT infrastructure and the necessary modifications to a number of software. Here is a summary of the main changes:

1. New version of LISFLOOD

LISFLOOD version 3.2.0 is used in this GloFAS release. It includes important developments, such as:

• enhanced code capability to handle inputs;
• new netCDF readers based on xarray that allow for more flexibility and efficiency, dramatically decreasing the time required to load large inputs thus leading to improved computational performances;
• extensive use of unit tests to verify the functioning of the model and enhance collaborative development of the code;
• improvements of the management of latitude and longitude grids to allow maximum precision of the reference system;
• porting of the code to python3.

The modelling of the hydrological processes has not changed compared to the version of the model used in the previous GloFAS release.
