2600 stations from over 70 participating organizations available in the West
Data processed & quality controlled & graphical products generated every 15 minutes
Still transitioning to new database
Typically, 15-30 minute time delay, e.g., observation at top of hour available at 15-30 minutes past hour
Available in AWIPS & FX-Net but more info available via Internet

Utah ADAS- Integrating MesoWest Utah ADAS- Integrating MesoWest Observations with NCEP RUC2AnalysesObservations with NCEP RUC2Analyses ADAS is a tool to monitor
current conditions based upon MesoWest surface observations
Uses NCEP RUC2 analysis from previous hour as background field to define overall spatial structure
Background field interpolated to high resolution grid (10 km or 1 km)
Observations are used to correct background field
Current Utah versions of ADAS– 2D surface analyses at 10km
resolution over western U.S. every 15 minutes
• Available 45 min after valid time• In AWIPS; FX-NET
– 2D surface analyses at 1km resolution over northwest Utah every 15 minutes
• Available 45 min after valid time• AWIPS?; FX-NET?
– 3D analyses at 1km resolution over northwest Utah every hour
• Available +1:30 after valid time• AWIPS?; FX-NET?

Automated Observations Automated Observations
All Temp, RH, wind sensors currently pass QC tests but many affected by siting
Wind sensors at most sites with precip gauges are NOT representative of general conditions
Acoustic snow depth sensors used for: (1) total snow & (2) interval snow
SWE is the hardest variable to measure and process automatically:Seven different types of automated precipitation gauges in northern Utah
Geonor/Belfort (accumulating) and ETI sensors (event) precip gauges at Outdoor venues
Precipitation during IPEX: Feb 2000
Reliable communication to automated stations remains an issue• dedicated phone lines• radio• cell phones
