Welcome to the WRF/WRFDA/WRF-Chem/MPAS Users' Support Forum, please read the guidelines & suggestions below.
You must create an account to post, first-time posts need manager approval and it may take 2-3 business days.
Before posting, use the search utility to verify whether a solution to your inquiry already exists
Post inquiries to the relevant forum and open a new thread for each new question. Do not post inquiries more than once.
State the problem or error in the subject line and attach relative files - e.g., namelists, error logs
Under "Options" check the boxes for "Watch this thread..." and "receive email notifications" to stay up to date on replies. Alternatively, click your name at the top of the forum site, and then "preferences" to choose notification options for the entire forum site.
There is no need to quote the previous post unless you are quoting a specific section. It is assumed your response is to the most recent submission.
Avoid attaching screen shots of error messages, as the content is not searchable.
If attaching packaged files, use zipped or .tar format (not .rar format).
If files are too large to upload, package files as a single .tar file, and upload to our Nextcloud storage, and then let us know the file name or link to the file. You can also view any uploaded files.
The NCAR team tries to reply to inquiries in a timely manner, but it can sometimes take a few days due to other obligations.
The NCAR team does not work nights (Mountain Time), weekends, or holidays.
We welcome experienced users to respond to inquiries. This helps expedite the response process.
This is the official NCAR-supported forum for the WRF & MPAS models. While other similar forums may exist and be perfectly functional, we are not affiliated with any forum outside of this one.
Prior to June 2022, this forum used a different platform. All content from the older platform can be found in the "Historical/Archive" section further down on this page.
