. The De-Icing Comparison Experiment (D-ICE): A study of broadband radiometric measurements under icing conditions in the Arctic

Abstract
The De-Icing Comparison Experiment (D-ICE) was a campaign carried out at the NOAA observatory in Utqiaġvik, Alaska, from August 2017 to July 2018. 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 operational stations run by NOAA and the DoE-ARM North Slope of Alaska (NSA) and Oliktok Point (AMF3) observatories. All radiometers were monitored continuously using cameras, and a total of more than 1 million images of sensor domes were archived. The data are used to calculate both the effectiveness of the ventilators in mitigating ice formation and biases associated with icing that does occur. Results are used to formulate recommendations for the operational and end-user communities.
