The rapid increase in the near-surface air temperatures and the drastic retreat of the Arctic sea ice during summer are not well represented by climate models. The data sets introduced here intend to help improving the current understanding of the ongoing Arctic climate changes. In particular, this study considers observations from 24 helicopter flights (June\u2013September 2020) and 5 flights with the helicopter-towed probe HELiPOD (May\u2013July 2020) during MOSAiC. Distributions of various surface types (white ice\/snow, bright melt ponds, dark melt ponds, open water, and bare ice) were determined using fisheye camera images. They were related to collocated broadband irradiance measurements to analyse the temporal and spatial changes of the surface albedo. Multiple linear regression was applied to assign the measured areal albedo to the corresponding surface-types. The resulting surface-type fractions, the albedo data and respective upward and downward broadband solar irradiances of several flights throughout the melting and refreezing season are provided.<\/jats:p>","DOI":"10.1038\/s41597-023-02492-6","type":"journal-article","created":{"date-parts":[[2023,9,6]],"date-time":"2023-09-06T12:01:32Z","timestamp":1694001692000},"update-policy":"http:\/\/dx.doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Surface albedo measurements and surface type classification from helicopter-based observations during MOSAiC"],"prefix":"10.1038","volume":"10","author":[{"ORCID":"http:\/\/orcid.org\/0000-0002-5891-7597","authenticated-orcid":false,"given":"Tim R.","family":"Sperzel","sequence":"first","affiliation":[]},{"given":"Evelyn","family":"J\u00e4kel","sequence":"additional","affiliation":[]},{"ORCID":"http:\/\/orcid.org\/0000-0003-2126-8367","authenticated-orcid":false,"given":"Falk","family":"P\u00e4tzold","sequence":"additional","affiliation":[]},{"ORCID":"http:\/\/orcid.org\/0000-0003-1414-1616","authenticated-orcid":false,"given":"Astrid","family":"Lampert","sequence":"additional","affiliation":[]},{"given":"Hannah","family":"Niehaus","sequence":"additional","affiliation":[]},{"ORCID":"http:\/\/orcid.org\/0000-0003-0165-8448","authenticated-orcid":false,"given":"Gunnar","family":"Spreen","sequence":"additional","affiliation":[]},{"given":"Sophie","family":"Rosenburg","sequence":"additional","affiliation":[]},{"given":"Gerit","family":"Birnbaum","sequence":"additional","affiliation":[]},{"given":"Niklas","family":"Neckel","sequence":"additional","affiliation":[]},{"ORCID":"http:\/\/orcid.org\/0000-0002-4652-5561","authenticated-orcid":false,"given":"Manfred","family":"Wendisch","sequence":"additional","affiliation":[]}],"member":"297","published-online":{"date-parts":[[2023,9,6]]},"reference":[{"key":"2492_CR1","do
