This package was created with Cookiecutter and the Ouranosinc/cookiecutter-pypackage project template.

History

0.4.1

• Add notebook about hindcast verification skill.

• Add notebook about routing capability.

• Modify geoserver functions to have them return GeoJSON instead of GML.

• Collect upstream watershed aggregation logic.

• Fix RVC bug.

0.4.0

This is an interim version making one step toward semi-distributed modeling support. Model configuration is still in flux and will be significantly modified with 0.5. The major change in this version is that model configuration supports passing multiple HRU objects, instead of simply passing area, latitude, longitude and elevation for a single HRU.

• GR4JCN emulator now supports routing mode.

• Add BLENDED model emulator.

• DAP links for forcing files are now supported.

• Added support for tox-based localized installation and testing with python-pip.

• Now supporting Python 3.7, 3.8, and 3.9.

• Build testing for pip and conda-based builds with GitHub CI.

0.3.1

• Update external dependencies (Raven, OSTRICH) to facilitate Conda packaging.

0.3.0

• Migration and refactoring of GIS and IO utilities (utils.py, utilities/gis.py) from RavenWPS to RavenPy.

• RavenPy can now be installed from PyPI without GIS dependencies (limited functionality).

• Hydro routing product is now supported from geoserver.py (a notebook has been added to demonstrate the new functions).

• New script ravenpy aggregate-forcings-to-hrus to aggregate NetCDF files and compute updated grid weights.

• Add the basis for a new routing emulator option (WIP).

• Add climpred verification capabilities.

0.2.3

• Regionalisation data is now part of the package.

• Fix tests that were not using testdata properly.

• Add tests for external dataset access.

• utilities.testdata.get_local_testdata now raises an exception when it finds no dataset corresponding to the user pattern.

0.2.2

• Set wcs.getCoverage timeout to 120 seconds.

• Fix Raven.parse_results logic when no flow observations are present and no diagnostic file is created.

• Fix ECCC test where input was cached and shadowed forecast input data.

0.2.1

• Fix xarray caching bug in regionalization.

0.2.0

• Refactoring of ravenpy.utilities.testdata functions.

• Bump xclim to 0.23.

0.1.7

• Fix xarray caching bug affecting climatological ESP forecasts (#33).

• Fix deprecation issue with Fiona.

0.1.6 (2021-01-15)

• Correct installer bugs.

0.1.5 (2021-01-14)

• Release with docs.

0.1.0 (2020-12-20)

• First release on PyPI.
