Radiosonde - temperature and humidity profiles

This dataset contains profiles of temperature and humidity observed by Vaisala RS92-K radiosondes that are launched nominally twice daily at Summit, Greenland. These radiosonde profiles do not contain any wind tracking information due to expense. The data are processed by the Vaisala software with the standard "EDT" processing ("wind nominal, PTU nominal" option), and are converted into netCDF format. The ICECAPS field operations at Summit are supported by the National Science Foundation's Arctic Observing Network (AON) Program. Note: In mid-2011, ICECAPS began launching one RS92-K and one RS92-SGP sonde per day. The former does not have wind sounding, but the latter does.
