Hi All,
SOCAAR is pleased to announce our final SOCAAR Seminar for 2014.
Tuesday, December 16, 2014 2-3 PM
200 College Street – WB407
Two Perspectives on Ultrafine Particles:
Modeling Size-Resolved Urban Traffic Impacts in Los Angeles, and One Year of Number Size Distribution Measurements in the North Central U.S.
Dr. Charles Stanier
Associate Professor
Chemical & Biochemical Engineering and IIHR Hydroscience and Engineering
University of Iowa
A 10 month field campaign monitoring the aerosol number size distribution was conducted in 2013 and 2014 at the long-term reference site in Bondville, Illinois. Results from this study, including diurnal and seasonal patterns and the influence of new particle
formation and growth events on the size distribution, will be discussed. The site is representative of a wide region of the Midwestern U.S. and is home to many long-term monitoring stations of NASA, NOAA, and the US EPA, including a 20+ year record of particle
number concentration and aircraft vertical profiles of optical properties, number concentration and particle number size distribution. Ongoing efforts to model the number size distribution and cloud nuclei concentration using nucleation explicit WRF-Chem will
be presented.
In a second portion of the talk, the University of Iowa Aerosol Screening Model (ASM), a physically-based vehicular UFP model for use in near-road environments, is evaluated versus 11 sites in the Los Angeles area and used to examine sensitivity of ultrafine
aerosols to road types, road proximity, and vehicle class.
If you are unable to join us for the seminar in person, we will be broadcasting the presentations live during the seminar using GoToMeeting software. Please feel free
to join us online using a web-browser or by calling in and using the webviewing software. If you do decide to join us, please remember to mute your microphone. If you have any questions during the meeting you are welcome to contact me by email, or by using
the GoToMeeting chat.
