Utah Basins Cache Valley Salt Lake Valley—Medium- sized partly open valley with large urban population Uintah Basin—Large very deep basin with small population Each basin has characteristic snow cover climatology and depth of ‘inversion’ resulting from confining topography Cache Valley Utah Valley Uintah Basin Great Salt Lake Basin Salt Lake Valley

Basic Weather Features Associated with Poor Winter Air Quality: Well-Understood H High pressure Cold, dirty air Warm, clean air Light winds

Critical Weather Details Associated with Poor Winter Air Quality: Difficult to Predict Clouds Snow Cover and Land Use Mixing Depth of polluted layer Transport Pollution concentrations

Improving Weather Models of Wintertime Inversions The EPA, Western Regional Air Partnership (WRAP) and Utah Division of Air Quality (UDAQ) have identified need for improved meteorological models Collaborative effort (July 2014-January 2016) between UofU and UDAQ funded by the Utah Legislature Builds on collaborative work with Utah State University

Weather Research and Forecasting Model (WRF) Full-physics meteorological model Model time step in inner domain ~5 seconds Run in parallel on processors Parameterizations for clouds, radiation, surface fluxes, turbulent mixing, precipitation, etc Grid spacing = 12 km Grid spacing = 4 km Grid spacing = 1.3 km

Improvements Being Tested For Wintertime Modeling in Utah Basins 1) Cloud and mixing algorithms 2) Model grid spacing 3) Model initialization 4) Snow cover and vegetation See 2 posters for more detailed information Liquid Ice
