- Release 1.1.3
- Fixed/Enhanced the cloud top temperature diagnostic.
- Optical depth was not being calculated correctly when cloud ice mixing ratio was not available.
- Fixed an indexing bug that caused crashes on Windows, but should have been crashing on all platforms.
- Users can now specify if they want cloud free regions to use fill values, rather than the default behavior of using the surface temperature.
- Users can now specify the optical depth required to trigger the cloud top temperature calculation. However, the default value of 1.0 should be sufficient for most users.
- Added ‘th’ alias for the theta product.
- Fixed a crash issue related to updraft helicity when a dictionary is used as the input.
- Dictionary inputs now work correctly with xy_to_ll and ll_to_xy.
- The cape_2d diagnostic can now work with a single column of data, just like cape_3d.
- Release 1.1.2
- Fix OpenMP directive issue with cloud top temperature.
- Release 1.1.1
- Added script for building on Cheyenne with maxed out Intel settings, which also required a patch for numpy.distutils.
- Fixed a few unicode characters hiding in a docstring that were causing problems on Cheyenne, and also building the docs with Sphinx on Python 2.x.
- Fix issue with np.amax not working with xarray on Cheyenne, causing an error with the mdbz product.
- Fix cape_2d private variable bug when running with multiple CPUs.
- Release 1.1.0
- Computational routines now support multiple cores using OpenMP. See Using OpenMP for details on how to use this new feature.
- The CAPE routines should be noticeably faster, even in the single threaded case (thank you supreethms1809!).
wrf.getvar()now works correctly with non-gridded NetCDF variables
- The cloud fraction diagnostic has changed:
- Users can now select their own cloud threshold levels, and can choose between a vertical coordinate defined as height (AGL), height (MSL), or pressure.
- The default vertical coordinate type has been changed to be height (AGL). This ensures that clouds appear over mountainous regions. If you need the old behavior, set the vert_type argument to ‘pressure’.
- Fixed a bug involving the cloud threshold search algorithm, where if the surface was higher than the threshold for a cloud level, the algorithm would use whatever was there before (uninitialized variable bug). This caused some interesting visualization issues when plotted. Now, whenever the surface is above a cloud level threshold, a fill value is used to indicate that data is unavailable for that location.
- The cartopy object for LambertConformal should now work correctly in the southern hemisphere.
- Fixed a bug with the PolarStereographic projection missing a geobounds argument (thank you hanschen!).
- Renamed the modules containing the ‘get_product’ routines used
wrf.getvar()to avoid naming conflicts with the raw computational routine names. Users should be using
wrf.getvar()instead of these routines, but for those that imported the ‘get_product’ routines directly, you will need to modify your code.
- Fixed a uniqueness issue with the internal coordinate cache that was causing crashes when input data is changed to a different file in a jupyter notebook cell.
- Added code to better support building wheels on Windows (thank you letmaik!)
- Improved support for scipy.io.netcdf objects.
- Added a new ‘zstag’ diagnostic that returns the height values for the vertically staggered grid.
- A DOI is now available for wrf-python. Please cite wrf-python if you are using it for your research. (See Citation)
- Fixed issue with vertcross and interpline not working correctly when a projection object is used. Users will now have to supply the lower left latitude and longitude corner point.
- Beginning with numpy 1.14, wrf-python can be built using the MSVC compiler with gfortran. WRF-Python can now be built for Python 3.5+ on services like AppVeyor.
- Release 1.0.5
- Reduced the CI test file sizes by half.
- Release 1.0.4
- Fix warnings with CI tests which were caused by fill values being written as NaN to the NetCDF result file.
- Added the __eq__ operator to the WrfProj projection base class.
- Fixed array order issue when using the raw CAPE routine with 1D arrays.
- Relase 1.0.3
- Fixed an issue with the cartopy Mercator subclass where the xlimits were being calculated to the same value (or very close), causing blank plots.
- Release 1.0.2
- Fixed issue with the wspd_wdir product types when sequences of files are used.
- Release 1.0.1
- Fixed issue with initialization of PolarStereographic and LatLon map projection objects.
- Fixed issue where XTIME could be included in the coordinate list of a variable, but the actual XTIME variable could be missing. NCL allows this, so wrf-python should as well.
- Release 1.0.0.
- Fixed issue with not being able to set the thread-local coordinate cache to 0 to disable it. Also, the cache will now correctly resize itself when the size is reduced to less than its current setting.
- Fixed an issue with the ‘0000-00-00 00:00:00’ time used in geo_em files causing crashes due to the invalid time. The time is now set to numpy.datetime64(‘NaT’).
- Fixed issue with wrf.cape_3d not working correctly with a single column of data.
- Beta release 3.
- Improvements made for conda-forge integration testing.
- Fixed an incorrectly initialized variable issue with vinterp. This issue mainly impacts the unit tests for continuous integration testing with conda-forge, since the data set used for these tests is heavily cropped.
- Back-ported the inspect.BoundArguments.apply_defaults so that Python 3.4 works. Windows users that want to try out wrf-python with Python 3.4 can use the bladwig conda channel to get it.
- Beta release 2.
- xarray 0.9 no longer includes default index dimensions in the coordinate mappings. This was causing a crash in the routines that cause a reduction in dimension shape, mainly the interpolation routines. This has been fixed.
- Documentation updated to show the new output from xarray.
- Beta release 1.
- Added more packaging boilerplate.
- Note: Currently unable to build with Python 3.5 on Windows, due to issues with distutils, numpy distutils, and mingw compiler. Will attempt to find a workaround before the next release. Windows users should use Python 2.7 or Python 3.4 for now.
- Alpha release 3.
- Added docstrings.
- The mapping API has changed.
- The projection attributes are no longer arrays for moving domains.
- Utility functions have been added for extracting geobounds. It is now easier to get map projection objects from sliced variables.
- Utility functions have been added for getting cartopy, basemap, and pyngl objects.
- Users should no longer need to use xarray attributes directly
- Now uses CoordPair for cross sections so that lat/lon can be used instead of raw x,y grid coordinates.
- Renamed npvalues to to_np which is more intuitive.
- Fixed issue with generator expressions.
- Renamed some functions and arguments.
- Currently unable to build on Windows with Python 3.5+ using open source mingw compiler. The mingwpy project is working on resolving the incompatibilities between mingw and Visual Studio 2015 that was used to build Python 3.5+. Numpy 1.13 also has improved f2py support for Python 3.5+ on Windows, so this will be revisited when it is released.
