ICECHIP: 5hPa Resolution Radiosonde Composite
Summary
5 hPa vertical resolution radiosonde data from research and operational sources during the ICECHIP (In-situ Collaborative Experiment for the Collection of Hail In the Plains) campaign converted into a common format (EOL Sounding Composite format which is a columnar ASCII format). The composite includes data from radiosondes from locations around the central United States. The radiosondes were released by the mobile Northern Illinois University system (five second resolution) and NOAA/NWS (28 sites at one second resolution). A total of 2188 radiosondes are included in this dataset.
Archive note
Most NWS stations had typical releases times of 00 and 12 UTC. However, a number of stations had variations on this schedule during ICECHIP. NIU Black released radiosondes during ICECHIP IOP operations.
