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.

Special Sub-Session on Mesoscale Analysis at 2020 AMS 10th R2O Conf.

Dear forum members,

 

We would like to encourage forecasters to submit an abstract to our session topic for 2020 AMS 10th Conference on Transition of Research to Operations, entitled, "Improving R2O & O2R in the 0–18 Hour Forecast Range Linking Research and Operations to Forecasters’ Needs":

https://ams.confex.com/ams/2020Annual/webprogrampreliminary/Session52222.html

 

We are planning to organize special sub-session(s) on any issues related to biases of mesoscale analysis including RTMA/URMA and also NBM.

 

This would be a good opportunity to present and discuss your issues to/with the fellow forecasters, developers, and policy makers.  The submission is originally due today (Aug. 8), but it would be further extended to Aug. 15.

 

FYI, here are the links to our sessions in the previous years:
 
2019 AMS (affected by the government shutdown; half of the talks cancelled)
 
2018 AMS

  • RAP downscaling conference preprint (23rd IIPS)

    This link is to a presentation from the (then) RUC group on how the downscaling process works. Although we now use the RAP, HRRR, and NAM, the logic of the downscaling code is mostly unchanged from this point.
