Planetary Boundary Layer (PBL) Air Quality Research

Recent Air Quality Field Programs

Health of the Atmosphere

• New England Air Quality Study (NEAQS) (New England)
• Central California Ozone Study (CCOS) - Model Verification
• Vertical Transport and Mixing Experiment (VTMX) (Salt Lake City)
• Texas 2000 Air Quality Study (TexAQS 2000) (Houston)
• California Air Resources Board (CARB) - ongoing (California)

Coastal Air Quality PBL Issues

• Land-Sea Breeze and coastal front (soil moisture, synoptic forcing)
• Complicated SST structure (upwelling, coastal current systems, eddies)
• Internal PBL's and transitions stable - unstable
• Stable PBL fundamentals(SHEBA data/analysis)
• Surface turbulent deposition (gas, particles)
• Surface wave - flux interactions (standard bulk relationships)
• Model assimilation of mesonet (profilers, surface obs, scanning radars)
