GIS4WRF offers the possibility to show contour plots of WRF parameters in a WRF layer, but vector plots are not supported yet (e.g. wind vectors made from e.g. U10 and V10)
Describe the solution you'd like
I propose to add a feature to show vector plots. Preferably combined with an underlying contour plot. Example: wind speed vectors with wind speed mangitude as underlying contour field. Extra add-on would be to colour the vectors with the wind speed magnitude.

currently it's a weird ce7wpv7vyit0w3mxlqqn

For analysis, it would be nice to create derived parameters. Example: wind speed magnitude, created from 2D fields U10 and V10, or 3D fields U and V.

The following namelist.input parameters do not appear as a namelist option and cannot be added manually as they are ignored.

run_days
run time in days
Type: int
Example: 0

run_hours
run time in hours *note: if it is more than 1 day, you may use both run_days and run_hours or just run_hours. e.g. if the total run length is 36 hrs, you may set run_days = 1, and run_hours = 12, or run_days = 0, and run_hours = 36
Type: int
Example: 0

run_minutes
run time in minutes
Type: int
Example: 0

run_seconds
run time in seconds
Type: int
Example: 0

We currently ship GIS4WRF with pre-built WPS and WRF v3.9 binaries for Windows. These need to be updated to the the latest release (v4).

At the moment we use a mixture of os.path and pathlib for representing file-system paths.
We should refactor to use exclusively pathlib.

Describe the bug
In tab "Run"/WRF "Visualize output only wrfout, wrfinput, wrfbdy can be selected, but not wrfrst,
To Reproduce
Steps to reproduce the behavior:

1. Go to 'Run
2. Click on WRF/"Visualize output '

Expected behavior
Ädd wrfrst

Describe the bug
The WRF tutorial does not run on 8 cores, 4 cores, neither. 2 cores is OK

Expected behavior
Mention on the page that it only runs with 2 cores as the tutorial domain is too small to be paralellized.

Operating System Information (please complete the following information):
Windows 10

Describe the bug
Editing the following namelist.input fields is not possible currently as they always get overridden to a default value:

• time_control: history_interval, frames_per_outfile
• domains: e_vert

There are more fields that get overridden, but those are derived directly from the domain and met data and it doesn't make sense to change them (e.g. interval_seconds or dx).

To Reproduce
Steps to reproduce the behavior:

1. Create a GIS4WRF project
2. Open the WRF namelist editor
3. Edit one of the mentioned fields
4. Open the editor again and observe that they have been overridden

Expected behavior
The fields above should be inserted initially, but once they exist the user should be able to change them.

Technical note: See project.py:update_wrf_namelist() and project_to_wrf_namelist.py.

Describe the bug
There is a possibility to change/save the namelist.wps configuration file. However, after starting ungrib, the namelist.wps is 'overwritten'by the default values (saved changes are lost).

To Reproduce
Steps to reproduce the behavior:

1. Go to Run
2. Click on 'Open configuration.', make changes and "Save"
3. Click on 'Run Ungrib'
4. Check content of namelist.wps to see that changes made earlier are lost

Expected behavior
Changes should not be overwritten

Operating System Information (please complete the following information):

• Windows 10

The others are working.

Simplify readme and include clear installation instructions. Update documentation to reflect what's new.

Is your feature request related to a problem? Please describe.
I was unable to find a possibility to visualize binary data produced by ungrib. When selecting "Visualize output" in Run/WPS tab, only geo_em / met_em files can be selected.
Describe the solution you'd like
Visualize binary data from ungrib

At the moment we do not handle cases where the PATH to WPS/WRF has not been set and the user creates/open a GIS4WRF project. I think that we should still allow users to open existing projects even if the PATH to WPS/WRF has not been set. The question is really if we want to limit access to Data and Run sub tab as those depends on the table files found in WPS.

Currently we support GIS4WRF for Python version 3.6 and above. If we want to support Ubuntu 16.x, we need to add Python support from version 3.5 as this is the version that ships with APT (see: https://packages.ubuntu.com/xenial/python3). Given that for all the other versions of Ubuntu, Python 3.6 is the default version on APT, the question is whether we think that there is enough demand for Ubuntu 16.x to justify the work.

I note that 16.4 and 18.4 are both long-term support (LTS) releases, released on 2016-04-21 and 2018-04-26 respectively.

Currently a vertical level can be selected by entering a level number. Is it possible to add a slider (similar to the time slider) for the vertical levels?

When i try to visualize the results it gives me this error:
I am using QGIS3.2 on Ubuntu 18.4
Thanks

GIS4WRF allows to run WPS and WRF binaries on local systems. The tool could be enhanced by allowing for remote execution of the wrf program.

In order to offer such support, we first need to understand which platform and job management system is most commonly used by the community.

Please add your specific requirements to this thread so that we can have a better idea of your specific requirements.

In Datasets > Geo we currently display the dataset name followed by the dataset filename. We should add the dataset name and swap the order to dataset name: dataset label-- e.g. varsso: varsso.tar.bz2 -> Variance of sub-grid-scale orogoraphy: varsso.

'Import from namelist' button is currently unimplemented -- this feature was part of a legacy component that was mistakenly added when moving to the public release. We should decide if we want to support this feature or deprecate it and remove it with our next release.

Currently the outputs are loaded back in QGIS as a raster. Ideally you should use mesh layer API to load the grib directly in QGIS 3.2+:
https://twitter.com/lutraconsulting/status/1018809991103500288

If your output contains vector, it will be displayed as a part of your mesh layer. You can also explore the time dimension.

We sometimes notice that geographical data is not everywhere correct (landuse in south-west NL shows glacier, which in fact is an area with a lot of green-houses).
Describe the solution you'd like
Offer the possibility to change data in WRF netcdf files, like the geo_em file. Pick a pixel (or select pixels with a polygon tool), change its value(s) and write the file

Allows uses to install and update GIS4WRF using the integrated plugin manager in QGIS. See https://github.com/GIS4WRF/gis4wrf/tree/dmey/qgis-plugin-repo

Describe the bug
It is not possible to generate multiple WRF layers in QGIS

To Reproduce
Select Layer/Add Layer/Add WRF NetCDF layer
Click on a WRF netCDF file

Existing WRF layer is replaced by the new dataset, instead of added.

Expected behavior
I would expect to see another layer that can be clicked on/off.

Further, it is not possible to create layers based on the same dataset (e.g. create layers for multiple parameters from the wrfout file)

Operating System Information (please complete the following information):
Windows 10

Right now a user only has one option to download met data within GIS4WRF. The only option needs an account. This is very limited.

The idea is to allow the user to download the met data the way they want and give them the responsability to provide the necessary information to GIS4WRF to 'discover' these datasets:

• dataset folder location
• dataset folder name (format)
• individual files name (format)
• ...

This is more flexible than adding datasets or new sites to GIS4WRF via code and gives the user the ability to download a bunch of files in an automated way instead of having to select one by one the potential possibilities from a dataset from rda.ucar.edu.

We do not yet ship WPS and WRF pre-built binaries for macOS. We can look into including pre-built WPS and WRF v4 binaries for macOS if there is enough demand. Let me know -- add your comments below.

When trying to save a namelist (.wps or .input) using the GIS4WRF editor (the editor launched when clicking on Open Configuration under Simulation > Run), the following syntax error is raised:

Describe the bug
When changing the colors in "Symbology" to "Paletted/unique values" and a color ramp (e.g viridis), the colors don't change when moving the time slider. To me it seems a bug, but it could also be related to my basic experience with QGIS ;)

Hi all,
I'd like to test the GIS4WRF plugin on my Ubuntu (Kubuntu) 18.04 LTS running QGIS 2.18.17, however GIS4WRF does not seem to show up on the list of available plugins...
Any idea on what would be the cause of this issue?
Genito

In Datasets > Met we only show dataset identifiers without its descriptive name. We should show a tool tip with the dataset name when hovering over the dataset identifier.

Describe the bug
When loading an existing project then in certain cases the geographic data selection input fields are only partly filled in even though all fields had been filled in before.

To Reproduce
Steps to reproduce the behavior:

1. Follow tutorial instructions
2. Close/re-open QGIS
3. Load the tutorial project
4. Observe "Selection" input fields may be partly empty.

The JSON project file has all information correct, so this is just a UI issue. It doesn't seem to happen all the time.

The typcal locking of files on Windows... Rerunning WPS/WRF after a file has been opened and closed results in PermissionError on Windows:

PermissionError: [WinError 32] The process cannot access the file because it is being used by another process

This is really a driver (GDAL) problem but we should handle it in some way.

Is your feature request related to a problem? Please describe.
Contour plots are supported by GIS4WRF, but isolines not.
Describe the solution you'd like
I propose to add a feature to plot isolines. Example: pressure isolines. Here is an example (combined with coloured wind speed vectors):

Is your feature request related to a problem? Please describe.
In geographical data, it is not clear which DataSet groups contain all essential data for running geogrid.
Describe the solution you'd like
Only specify datasets (e.g. lowres, default) that contain geographical data to run geogrid

We use wrf-python to show derived variables. These are indicated with a trailing * in the variable list in the View tab. It would be good to add a note in some form in this tab that explains what * variables are and that they are produced by wrf-python.

When clicking on Visualize output button, wrfbdy files are included in the current list. These can be removed as they only contain boundary condition information for the WRF program.

If nothing more descriptive is available, the GH repo address can do it.
Thanks.
