University of Utah Mesonet

General Chatter

I am pretty sure someone talked about this on the forum, but University of Utah (url http://www.met.utah.edu/jhorel/html/mesonet/ ) has a new mesonet system up, where using clickable map images you can select to display NWS, RAWS, and APRS station observations. I like better than some of the others because you do not need to waste time loading a java app and lots of stations you don’t need. I have noticed that not all of the APRS station are showing. It appears that people using ham call signs rather than the weather signs (CWXXXX) are the only ones showing their data. I was just wondering if anyone had any clue why?

Thanks Chris,

The correct link is

Without the ) on the end.

I do not see data from CWXXXX stations. The CWXXXX stations are plotted on the map. When clicked on this is what I get:
Weather Conditions for C0692
Current time: October 15, 2003 - 17:54 EDT
Most Recent Observations at
There is no data in the database for C0692 during the requested time period.
Below is a list of nearby stations that have reported data at least once in the last 90 days.

You’re picking on him because of a “)” and you can’t get the station code right?

Maybe this is why. The site is part of “ROMAN”.
“ROMAN has been designed for use by fire weather professionals and others requiring access to current fire weather conditions around the nation.”

Howdy,

I had heard the MesoWest folks were integrating the APRSWXNET/CWOP mesonet into there database. Looks like they did the “AR” and “AP” ham radio identifiers first, but the “CW” identifiers were added just today (still adding to the recent archive data continuity).
Check out the spike in # of stations when the “CW” stations were added:
http://www.met.utah.edu/jhorel/html/mesonet/monitor/APRSWXNET.gif

Mesowest’s use of our data speaks volumes for the expansion of CWOP, now with 2,500 registered members. Mesowest supports the Fire Weather program, State Department of Transportation(s), and initialize weather prediction models (e.g., the ADAS). Interesting that MesoWest runs their model with a resolution of 2.5Km or about 1.5 miles. They could not do this without a very high density of observations, which APRSWXNET/CWOP is now a significant contributor.

The Mesowest folks receive the CWOP data thanks in part to the Ham Radio Tier 2 node operators (Dick Stanich, et al), the FINDU server (Doc Steve Dimse), and the people at NOAA’s Forecast Systems Laboratory in Boulder, Colorado. APRSWXNET/CWOP would not exist without the strong support of the data logger developers, particularly Brian who received and award for his support (see the Weather-Display front page), and the CWOP data volunteers.

If you want to know more about CWOP, see the CWOP forum the weather-watch web page!

P.S. Here’s the News on CWOP and MesoWest from Forecast Systems Laboratory’s “Hot Items”, October 3, 2003:

The Citizen Weather Observer Program (CWOP) data stream is now being sent from the Forecast Systems Laboratory (FSL) Meteorological Assimilation Data Ingest System (MADIS - http://www-sdd.fsl.noaa.gov/MADIS) to MesoWest (http://www.met.utah.edu/mesowest/) in Salt Lake City, which in turn forwards the data to all Weather Forecast Offices (WFOs) in the Western Region of the National Weather Service (NWS). CWOP (http://www.wxqa.com/) is a program of volunteer observers, organized by FSL, who supply and operate their own weather instruments and contribute the real-time weather data to NOAA as a public service. Presently there are over a thousand CWOP data contributors. Their data, along with other mesonet data collected by the FSL MADIS program, are being sent to nearly 70 NWS WFOs across the country, and also to a wide variety of other users, including the National Centers for Environmental Prediction and the National Climatic Data Center. A full list of the MADIS mesonet data providers can be found at http://www-dd.fsl.noaa.gov/MADIS/mesonet_providers.html. Real-time displays of the mesonet observations are available at the website below.

Thanks everyone. :smiley: That answered my question.
