Cloudwater measurements of sulfur , nitrogen and organic species during icartt

Clouds play an important role in the processing and transport of atmospheric aerosols and trace gases. These processes, although identified, are generally not well understood and often are not included in the cloud representations of regional air quality models. In particular, there is a lack of field experimental data to investigate the influence of clouds on particle chemistry. During the summer of 2004, in collaboration with the ICARTT (International Consortium for Atmospheric Research on Transport and Transformation) field intensive, measurements were made to study the Chemical transport and Transformation by Cloud (CTC).
