| 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
|
|
|
| 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 |
| MesoNorthwest: Regional Weather Observations and Analyses | Access to all available weather observations over the Northwest. |
