A14A:
Emissions and Tropospheric Photochemistry on the Urban Scale II

Submit an Abstract to this Session Please know the abstract submission deadline has passed. There are no exceptions to this deadline and no new abstracts can be submitted.
You can still search the program to see your colleague�s abstract submissions as well as the sessions submitted for the 2016 Fall Meeting. The final program will be released in early October.


Session ID#: 16171

Session Description:
Direct action to control emissions as well as high population densities make the urban scale a focus of atmospheric chemistry and fine-scale meteorology.  This session welcomes contributions on

  • evaluation of emissions and fluxes of short-lived pollutants and greenhouse gases 
  • photochemistry and air quality
  • the impact of processes such as the urban heat island and sea-breeze on the weather and  environment. 

The session is dedicated to practical application of fundamental physics and chemistry to improve understanding of the processes that generate ozone and other pollutants as well as direct measurement methods for emissions of reactive pollutants (e.g., CO, VOCs, and NOx from vehicles), climate forcing substances (e.g., CO2 , CH4 and black carbon) and circulation drivers on the urban scale.
