De-Icing Comparison Experiment (D-ICE) campaign data: Best-estimate downwelling longwave and shortwave radiometric fluxes from the NOAA Barrow Atmospheric Baseline Observatory, August 2017-July 2018 (NCEI Accession 0209058)

The De-Icing Comparison Experiment (D-ICE) was carried out at the NOAA Atmospheric Baseline Observatory in Utqiagvik (formerly Barrow), 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 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).
