High vertical resolution sounding data from research and operational sources during the Cold Air Outbreak Experiment in the Sub-Arctic Region (CAESAR) campaign converted into a common format (EOL Sounding Composite format which is a columnar ASCII format). The composite includes data from 568 radiosondes and 116 dropsondes from locations around the Norwegian Sea.
