The purpose of D-ICE was to evaluate ventilation and heating technologies developed to mitigate radiometer icing. D-ICE consisted of 20 pyranometers and 5 pyrgeometers operating in various ventilator housings alongside the Baseline Surface Radiation Network (BSRN) station operated by NOAA. Broadband downwelling longwave and shortwave fluxes were measured and the radiometers were monitored using cameras. Icing conditions and occurrences of ice on radiometer domes were recorded based on manual review of the camera images. This data set contains one minute averages of the radiometric data, the icing determinations and ancillary data (such meteorology and housekeeping information form the sensors). Three versions of the fluxes are provided: the raw data (no quality control), data that is quality-controlled and verifiably ice-free, and data that is quality controlled but where occurrences of ice contaminated measurements are retained. The data set is suitable for analysis of the effects of ice on broadband radiometric data. This dataset is available to the public for a wide variety of uses including scientific research and analysis. completed historicalArchive NOAA National Centers for Environmental Information ncei.info@noaa.gov https://www.ncei.noaa.gov/contact HTTPS NCEI Contact Information Information for contacts at NCEI. information pointOfContact asNeeded https://www.ncei.noaa.gov/access/metadata/landing-page/bin/gfx?id=gov.noaa.nodc:0209059 Preview graphic PNG 0209059 NCEI ACCESSION NUMBER 2020-01-08 publication AIR TEMPERATURE dew point RELATIVE HUMIDITY WIND DIRECTION WIND SPEED theme NODC DATA TYPES THESAURUS pyranometer instrument NODC INSTRUMENT TYPES THESAURUS laboratory experiments theme NODC OBSERVATION TYPES THESAURUS NOAA Earth System Research Laboratory dataCentre NODC SUBMITTING INSTITUTION NAMES THESAURUS aerology theme WMO_CategoryCode 2012-09-15 publication EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC RADIATION > SOLAR IRRADIANCE EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC TEMPERATURE EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC TEMPERATURE > SURFACE TEMPERATURE > DEW POINT TEMPERATURE EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC WATER VAPOR > WATER VAPOR INDICATORS > HUMIDITY > RELATIVE HUMIDITY EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC WINDS > SURFACE WINDS > WIND DIRECTION EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC WINDS > SURFACE WINDS > WIND SPEED theme Global Change Master Directory (GCMD) Science Keywords 2026 revision 24 Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA) Greenbelt MD https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords HTTPS GCMD Keyword Forum Page Global Change Master Directory (GCMD). 2025.
