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 and the nearby US Dept. of Energy (DoE) Atmospheric Radiation Measurement (ARM) North Slope of Alaska station. Broadband downwelling longwave and shortwave fluxes were measured and the instruments were monitored using cameras. Both camera images and conventional processing techniques were used to quality control and bias-correct the data. The performance of the ice-mitigation technologies was generally high and a large number of redundant measurements were made. Consequently, D-ICE afforded the opportunity to construct a well-characterized and verifiably ice-free data set of downwelling longwave and shortwave fluxes from Utqiagvik between 2017 August 26 to 2018 July 3 that is > 99% complete. This data set was produced by averaging data that passed quality assurance tests and constrained using the BSRN and ARM solar tracker measurements. Empirically derived uncertainties are also calculated, based on the spread of the redundant observations. This data set is suitable for satellite or model evaluation projects, such as the Year of Polar Prediction (YOPP) site Model Intercomparison Project (YOPPsiteMIP). 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:0209058 Preview graphic PNG 0209058 NCEI ACCESSION NUMBER 2020-01-08 publication 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 > LONGWAVE RADIATION EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC RADIATION > SHORTWAVE RADIATION theme Global Change Master Directory (GCMD) Science Keywords 2026 revision 23 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.
