The Sea Surface Temperature (SST) CPEX dataset consists of data from the Multi-scale Ultra-high Resolution (MUR) sensor, which measures global sea surface temperatures. The data were gathered during the Convective Processes Experiment (CPEX) field campaign, which began in early summer 2017. CPEX collected data to help answer questions about convective storm initiation, organization, growth, and dissipation in the North Atlantic, Gulf of America, and Caribbean Oceanic regions. These data files are available from May 23, 2017, through July 15, 2017, in netCDF-3 format.
