Pacific Northwest Environmental Forecasts and Observational Data
 
The regional environmental forecasts are supported by the Northwest Regional Modeling Consortium, a group of local, state, and Federal agencies and cooperating private companies. The goals of this effort are to produce operational atmospheric, hydrologic, and air quality forecasts over the Northwest.  The centerpiece of the effort is  the Penn State/NCAR mesoscale model (MM5), which produces high-resolution atmospheric forecasts that are used to drive a collection of environmental modeling systems. 
 

 Regional Operational Forecasts and Real-Time Observations


 
Selection
Description
MM5 Northwest Atmospheric Forecasting System The MM5 model is run twice a day for 60h at 36, 12 and 4-km horizontal resolution
MM5 Regional Atmospheric Ensemble System The MM5 model is run once a day for 48h at 36 and 12-km resolution using five different intializations and three different physics packages.
Hydrologic Forecasts for Major NW Rivers A distributed hydrologic model (DHSVM) is run daily, using precipitation and other fields from the real-time MM5
Northwest Air Quality Prediction System A regional air quality model (CALGRID) is run daily forced by the real-time MM5
Road Weather Information and Forecasts Weather observations/forecasts and road conditions for WA State roadways
