Joint Session 13 Chemistry, Aerosol, Cloud and Convection During the GoAmazon2014/5 Field Campaign I

Wednesday, 13 January 2016: 4:00 PM-5:30 PM
Room 357 ( New Orleans Ernest N. Morial Convention Center)
Hosts: (Joint between the Eighth Symposium on Aerosol–Cloud–Climate Interactions; and the 18th Conference on Atmospheric Chemistry )

Both aerosol properties and meteorology conditions in the Amazon Basin vary significantly among different seasons. Amazon Basin represents one of the most pristine and natural continental sites but polluted situations occur with the perturbations of tropical megacity pollution and biomass burning emissions. Past studies showed very complex interactions between chemistry, aerosols, clouds, and meteorology, and therefore, a challenge to understand and model convection and precipitation in the region. Very recent field experiments, including GoAmazon2014/15 and ACRIDICON-CHUVA, have been conducted over the Amazon region to reveal new insights in the complex interactions in Amazonia. This special session will discuss the new observational and modeling studies on meteorology, aerosols, clouds, convection and precipitation and the associated interactions related to the GoAmazon2014/15 and ACRIDICON-CHUVA. We will have invited talks, contributed oral and poster presentations. Student presentations are particularly encouraged. Cash prizes and a certificate from AMS will be awarded to outstanding first author student presentations.
