One new area examined by McNider in his opening talk was the evidence of too much mixing in nighttime stable boundary layers is reducing the decoupling and strength of associated inertial low level jets and shear in the residual layer between the surface and the previous day’s boundary layer height. Using long range dispersion results it was shown that such under-prediction of the decoupling can dramatically change the transport and spread of urban and power plant plumes into rural areas. It was hypothesized that part of the under-prediction in modeled rural NO2 columns compared to satellite column NO2 may be due to model under-estimates of NOy export from urban areas because of the under-estimate of the nighttime decoupling.

AQAST Newsletter, February 2014

AQAST Semiannual Meetings

AQAST meetings are held on a semiannual schedule and bring together team members, air quality managers, and research and applications partners. Our last meeting was held on January 15-17, 2014 at Rice University in Houston. You can access the agenda and presentations from that meeting here.

7th AQAST Meeting (AQAST7): June 17-19, 2014 at Harvard University

The next AQAST meeting (AQAST7) will be held June 17-19, 2014 (Wednesday-Friday) at Harvard University in Cambridge, MA, hosted by Dan Cohan. The meeting is free and open to the public. Air quality managers are especially encouraged to participate. Go to the meeting website for more information and to register. Indicate when you register if you would like to give a presentation. We look forward to seeing you in Cambridge in June!
