One can further simplify this code, as the major use of wrf-python here is just to create the projection (as in cart_proj = wrf. wrf-python might also be able to help you? It looks like they have routines for handling WRF output already: https: from netCDF4 import Dataset import xarray as xr import matplotlib. Here is the cartopy python code that was used to generate this plot from this WRF output file: wrf. 7. crs. However, my problem that the wrf-python module can not be imported when installing cartopy (Cartopy-0. Basemap object for the map projection. wrf-python includes several routines to assist with plotting, primarily for obtaining the mapping object used for cartopy, basemap, and PyNGL. A collection of diagnostic and interpolation routines for use with output from the Weather Research and Forecasting (WRF-ARW) Model. I have updated the cartopy version to 0. cm import get_cmap from matplotlib. I think those are conflicted because of numpy.

Here is an example: from netCDF4 import Dataset from wrf import getvar wrf-python includes several routines to assist with plotting, primarily for obtaining the mapping object used for cartopy, basemap, and PyNGL. R Initialize a wrf. Projection subclass for the map projection. cartopy Return a cartopy. The functionality is similar to what is provided by the NCL WRF package. The rest functions can all be implemented using just netCDF4 (or xarray) with some projection transformation, i. Interpolation routines (level, cross section, surface). plt. DataArray variable that includes latitude,longitude coordinate information. wrf. 5+ on services like AppVeyor. Cartopy is advertised as the future mapping, yet it is significantly slow compared to Basemap when I use large arrays. How to reduce the time of this cartopy plot . When But now I finally made the switch to wrf-python and cartopy since I needed to extract more information from my simulations (ie I needed to interpolate between different pressure levels). For all three plotting systems, the mapping object can be determined directly from a variable when using xarray, or can be obtained from the WRF output file(s) if xarray is turned off. When using the HTTPS protocol, the command line will prompt for account and password verification as follows. WRF-ARW only. But with Cartopy you should specify the projection of the source data (from which you want to transform I hope that you doing well and are able to solve your problem quickly. DataArray. wrf-python. ds = xr. When the installation completes, your command terminal might post a message similar to: On a related but separate note to the issue/request I posted in #171, I'd like to request that improved documentation be made when passing a variable and not a NetCDF4.
