Abstract

PBL heights from WRF/NMM and ETA models are verified for summer 2006 period with RAOBS observations. WRF/NMM model is also verified with PBL heights provided by profiler measurements during 15 days period of TexAQS experiment. For geographical regions, WRF/NMM produces higher than ETA boundary layers over Eastern US, and lower over Western US. Both models produce higher PBL than the RAOBS observations estimate. Richardson number approach used for model PBL height recalculations provides better agreement with RAOBS estimations. Updated WRF/NMM (NAMY) provides small improvement in PBL heights. In TexAQS experiment, the WRF/NMM model produces deeper boundary layer than the observations report. PBL heights computed from profiler data (TexAQS/Longview) are similar to RAOBS(SHV) data, although the profiler fits the model results better.
