The EOL Field Data Archive contains publicly available data from atmospheric research campaigns conducted by the National Science Foundation (NSF) and other agencies since about 1967. Datasets are collected from research instrumentation operated by NCAR and other organizations and investigators. The archive also contains selected operational datasets that the campaign investigators requested. Currently, there are some 590 field campaigns in the Field Data Archive and over 15,000 datasets.
