VISTAS Meteorological Modeling • 2002 Simulation • May 25, 2004 • National RPO Modeling Meeting • Denver, CO • George Bridgers • North Carolina Division of Air Quality
Introduction • MM5 v3.6.1+ (Sea Ice Differences Only) • MM5 v3.6.2 Preprocessors • Reisner 1 w/ Mixed Ice Physics • Kain-Fritsch 2 Cumulus Parameterization • ACM Planetary Boundary Layer (PBL) Model • Pleim-Xiu Land Surface Model LSM (EPA’s MPP version) • independent segments (cold start)-no INTERPPX • INTERPPXis used to initialize soil moisture, canopy moisture, and soil temperature from a previous run when simulation time periods overlap. • Using INTERPPX resulted in a significant wintertime cold bias in sensitivity testing.
Introduction (cont.) • MM5 executed in 5.5 day segments • 76 total segments • 00Z Dec 17, 2001 start • dec17_01 date tag • 12Z Jan 1, 2003 finish • Last hour of dec27_02 segment
Evaluation Procedures • Full suite of evaluation products available for each segment • Surface Products • Spatial • Time series • Combination • Aloft Products • Spatial • Sounding • Profiler • Statistical Products • Surface time series • Aloft time series • Tables
Evaluation Procedures • Need to Summarize Results • Monthly Products • Statistical Tables • Spatial Summary Plots • “Bakergrams” (annual) • “Bakergrams” (monthly) • Spatial Statistical Plots
