Welcome

Welcome to the RTMA/URMA VLab community!

The purpose of this community is to facilitate feedback and discussion on the RTMA/URMA system. 

Meeting notes are available under the Google Drive Folder linked above.

To learn more about our next upgrade, see the asset publication below.

Use the System Overview to learn more about the system in general.

Use the forum to ask questions about the system and join the discussion with other users and the development team. 

Note that there are two forums: one for precipitation issues and one for all other variables.

You can post to the precip issues forum by sending an email to qpe.rtma.urma.feedback.vlab@noaa.gov.  For all other issues, you can post by sending an email to rtma.feedback.vlab@noaa.gov.  Please note that you must have a user account to post to the forum.  If you do not have an account, please contact matthew.t.morris@noaa.gov.

We recently added the ability for NWS Regional or WFO personnel to request that stations be removed from the analysis.  To access this, click on the "Station Reject Lists and Requests" tab.

There has been recent interest in knowing exact station locations, especially those of METAR sites.  Our METAR information table is under the "METAR Location Info" tab.

Users may also be interested in the National Blend of Models VLab community.

We appreciate any feedback on how this page or community could be improved.  You can submit such feedback via the above email handle or forum.

New Station URMA in central Idaho

Youngling Posts: 18 Join Date: 1/19/16 Recent Posts

The station DIXI1 has been in AWIPS and mesowest for a while, but it isn't making it into the URMA.  Is there anything else we should do to get it added?

 

Thanks

Hi Ryan,

We are working with MADIS to get this station added.  The MADIS station tables must be updated in order to add this station, and these updates are done weekly on Wednesday.  I will follow-up once the observations are available, likely after the Thanksgiving holiday.

Thanks,
Matt

Hi Ryan,

The temperature and moisture observations from RAWS station DIXI1 are now being used in URMA. The change took effect with the 15Z URMA on November 23rd.

Thanks,
Matt
