The Moderate Resolution Imaging Spectroradiometer (MODIS) CPEX dataset includes measurements gathered by MODIS during the Convective Processes Experiment (CPEX) field campaign. The CPEX field campaign took place in the North Atlantic-Gulf of Mexico-Caribbean Sea region and conducted a total of sixteen DC-8 missions. The CPEX campaign collected data to help explain convective storm initiation, organization, growth, and dissipation in the North Atlantic-Gulf of Mexico-Caribbean Oceanic region during the early summer of 2017. Data are available from May 9, 2017 through July 16, 2017 in netCDF-3 format.
