It was based in Longyearbyen, Svalbard. In total, 11 low-level research flights and two transit flights were conducted, covering the region around Svalbard and north of Greenland.<br/>The datasets present upward and downward shortwave and longwave irradiance measurements, together with the corresponding sensor temperatures and GPS position. One pyranometer and one pyrgeometer were installed on the top of Polar 6, with an additional pyranometer and pyrgeometer installed on the underside of the aircraft. For convenience, the dataset also provides pitch and roll angles.</description></descriptions><geoLocations><geoLocation><geoLocationBox><westBoundLongitude>-16.663061</westBoundLongitude><eastBoundLongitude>15.502002</eastBoundLongitude><southBoundLatitude>78.245931</southBoundLatitude><northBoundLatitude>81.596627</northBoundLatitude></geoLocationBox></geoLocation></geoLocations><fundingReferences><fundingReference><funderName>German Research Foundation</funderName><funderIdentifier funderIdentifierType="Crossref Funder ID">https://doi.org/10.13039/501100001659</funderIdentifier><awardNumber awardURI="https://gepris.dfg.de/project/268020496">268020496</awardNumber><awardTitle>TRR 172:  ArctiC Amplification: Climate Relevant Atmospheric and SurfaCe Processes, and Feedback Mechanisms</awardTitle></fundingReference></fundingReferences></resource>
