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. The properties measured were snow grain size, snow crystal habit/form, and hand hardness. A layer identification was performed prior to these measurements. This profile was made 2-3 m away from the SLEIGH.\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,snow profile,hand hardness,crystal form,crystal habit,grain size,ICECAPS,ICECAPS-MELT,Camp Raven, Greenland Ice Sheet","publicationState":"citable","dataPublishedTime":"2026-01-30T14:55:53","doiPublishedTime":"2026-02-02T16:02:41.390808","updateFrequency":"notPlanned","status":"completed","result_field":{"ob_id":"https://catalogue.ceda.ac.uk/api/v2/observations/45220/?format=json","dataPath":"/badc/icecaps-melt/data/202408CampRavenSnowProps","oldDataPath":[],"storageLocation":"internal","storageStatus":"online","volume":3666,"numberOfFiles":2,"fileFormat":"Data are BADC-CSV formatted"},"timePeriod":"https://catalogue.ceda.ac.uk/api/v2/times/12628/?format=json","geographicExtent":"https://catalogue.ceda.ac.uk/api/v2/bboxes/4864/?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/92737/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/92763/?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/13702/?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/214490/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/214797/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/214492/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/214493/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/214494/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/214495/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/214496/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/214491/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/214957/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/214497/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/214498/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/214499/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/214500/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/214501/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/214502/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/214503/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/214504/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/214505/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/214506/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/214507/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/214508/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/214509/?format=json"],"procedureAcquisition":"https://catalogue.ceda.ac.uk/api/v2/acquisitions/44797/?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":[]}
