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.

Bad station in Forsyth, MT

Bad station in Forsyth, MT

Youngling Posts: 14 Join Date: 6/12/17 Recent Posts

We're noticing some really warm temps coming from Forsyth, MT (getting into URMA & NBM) and I think the reason is a cwop station that consistently reports 5-6° too warm. It is site E1247. Can you please blacklist this station so it doesn't corrupt URMA & the NBM? I have attached images of the station/location and an example DESI probability. Thanks!   -joe

There seems to be another bad station too...a HADs station at Edgar, MT (EDGM8). Daytime temps seem okay but nights are much too warm (I've seen things like that at other HADs stations...temps aren't always dependable). Also, the location of Kilo (K1KM) is off. It should be a little north of where I see it plotted. I have attached an image with the correct lat/long. Thanks!

Hi Joe,

I will get these two stations added to the reject list, as resources allow.  In general, we prefer these requests be submitted by the SOO using the Google form embedded in the RTMA/URMA VLab page at: https://vlab.noaa.gov/group/715073/observation-qc-requests

Regarding the location of Kilo (K1KM), the following page lists the location as 46.45N, 109.8W, which matches what we have currently.  https://metar-taf.com/airport/1KM-kilo-weather-station

I should also note that K1KM reports as both a METAR and mesonet station, and is, therefore, assimilated twice.  If you'd like, we could potentially add the mesonet station to the reject list, so that only the METAR reports are used going forward.  Please let us know if you'd like to do this.

Thanks,
Matt

Hi Joe,

E1247 and EDGM8 were both added to the reject list for temperature last Friday.

Thanks,
Matt
