Dr. Brocchi will model the chemistry and dynamics of nitrous oxide (N2O) using a global model. For this task she will learn to run CESM2 (WACCM). The N2O measurements available for this work will be based on aircraft, balloon, and satellite data for the period 1960-2016. In addition, Dr. Broccihi and Dr. Kinnison will also be working on this project with Professor A. R. Ravishankara, Department of Chemistry, Colorado State University. Dr. Brocchi will not need ACOM support.
