The snow profile measurements were made adjacent to an autonomous atmospheric and glaciological platform (the SLEIGH) as part of the ICECAPS-MELT (Integrated Characterization of Energy, Clouds, Atmospheric state, and Precipitation - MEasurements along Lagrangian Transects) experiment. A layer identification was performed and then snow properties were measured: snow grain size, snow crystal habit/form, and hand hardness. Profile 1 was measured on 15 May 2024, 2-3 meters from the eventual SLEIGH installation. Profile 2 was measured on 18 May 2024, 20 m from the eventual SLEIGH installation.\r\n\r\nThis work was US-led, US-UK collaboration co-funded by the US National Science Foundation and the UK National Environment Research Council.","keywords":"Greenland,Camp Raven,snow profile,grain size,hand hardness,layer identification,crystal form,crystal habit,ICECAPS,ICECAPS-MELT, Greenland Ice Sheet","publicationState":"citable","dataPublishedTime":"2026-01-30T17:29:10","doiPublishedTime":"2026-02-02T16:00:26.267736","updateFrequency":"notPlanned","status":"completed","result_field":{"ob_id":"https://catalogue.ceda.ac.uk/api/v2/observations/45221/?format=json","dataPath":"/badc/icecaps-melt/data/202405CampRavenSnowProps","oldDataPath":[],"storageLocation":"internal","storageStatus":"online","volume":4090,"numberOfFiles":3,"fileFormat":"Data are BADC-CSV formatted"},"timePeriod":"https://catalogue.ceda.ac.uk/api/v2/times/12629/?format=json","geographicExtent":"https://catalogue.ceda.ac.uk/api/v2/bboxes/4865/?format=json","nonGeographicFlag":false,"phenomena":["https://catalogue.ceda.ac.uk/api/v2/phenomona/92721/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/92731/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/92732/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/92733/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/92734/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/92735/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/92736/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/92737/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/92738/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/92739/?format=json"],"dataLineage":"Manual snow property measurements of snow grain size, snow crystal habit/form, and hand hardness were made using American Avalanche Association standards from Snow, Weather, and Avalanche Guidelines, 4th Edition, 2022. Snow grains > 0.5 mm were recorded to the nearest 0.5 mm, otherwise very fine grains recorded as 0.1, 0.3, 0.5 mm. The layer identification was done by sliding a snow crystal card downward through the snow pit face to test for changes in tensile strength. These layers were cross-checked against the visual appearance of each layer. The hand hardness classifications were converted to a 0-5 scale, with 0.5 increments allowed when the snow was determined to be in between two classifications.","removedDataTime":null,"removedDataReason":"","language":"English","identifier_set":["https://catalogue.ceda.ac.uk/api/v2/identifiers/13701/?format=json"],"projects":["https://catalogue.ceda.ac.uk/api/v2/projects/38309/?format=json"],"observationcollection_set":["https://catalogue.ceda.ac.uk/api/v2/observationcollections/44850/?format=json"],"responsiblepartyinfo_set":["https://catalogue.ceda.ac.uk/api/v2/rpis/214293/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/214792/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/214295/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/214296/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/214297/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/214298/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/214299/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/214294/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/214958/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/214300/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/214301/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/214302/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/214303/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/214304/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/214305/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/214306/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/214307/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/214308/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/214309/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/214310/?format=json"],"procedureAcquisition":"https://catalogue.ceda.ac.uk/api/v2/acquisitions/44760/?format=json","procedureCompositeProcess":null,"procedureComputation":null,"permissions":[{"ob_id":"https://catalogue.ceda.ac.uk/api/v2/observations/2528/?format=json","useLimitation":null,"accessConstraints":null,"accessCategory":"public","accessRoles":null,"label":"public: None group","licenceURL":"http://creativecommons.org/licenses/by/4.0/","licenceClassifications":"any, attribution required"}],"discoveryKeywords":[]}
