This dataset contains ER-2 DOPpler (EDOP) data collected during the Tropical Composition, Cloud, and Climate Coupling (TC4) field campaign, which took place in July 2007. TC4 focused on expanding our understanding of the chemical, dynamical, and physical processes that take place in the upper troposphere and the lower stratosphere over the tropical eastern Pacific. The field campaign collected observations from three aircraft (ER-2, DC-8, and WB-57) as well as multiple ground sites. The TC4 EDOP data is available in netCDF-4 format. The reprocessing efforts of this dataset are limited to the previously processed data files and did not delve into reprocessing the data from the raw files.
