Abstract: ### Access Files can be accessed and downloaded from the directory via: [https://arcticdata.io/data/10.18739/A2GT5FH75/](https://arcticdata.io/data/10.18739/A2GT5FH75/). ### Overview This dataset contains measurements of downwelling brightness temperature at 16 frequencies between 22.2 and 150 GHz (gigahertz) at approximately 5 s (second) temporal resolution. The observations were made by two radiometers (from Radiometer Physics GmbH) that are time-synced. This dataset contains only sky brightness temperatures; however, these data can be used to retrieve precipitable water vapor, cloud liquid water path, and profiles of temperature in the boundary layer. These radiometers periodically collect elevation scan data (horizon to horizon) that will be used to improve accuracy of the retrieved temperature profiles and to use for in-field calibrations (via tip-curve analysis). The radiometers are calibrated using liquid nitrogen approximately 4 times per year. The raw data are converted into netCDF format. The ICECAPS field operations at Summit are supported by the National Science Foundation's Arctic Observing Network (AON) Program.
