    "title": "ICECAPS-MELT: Manual and Instrumented Snow Property Measurements at Camp Raven, Southwest Greenland (May and August 2024)",
    "abstract": "This dataset collection contains manual and instrumented snow measurements collected at Camp Raven, located on the southwest sector of the Greenland Ice Sheet, during May and August 2024.\r\n\r\nThe measurements were made as part of the ICECAPS-MELT (Integrated Characterization of Energy, Clouds, Atmospheric state, and Precipitation - MEasurements along Lagrangian Transects) project, which extends the long-term ICECAPS program to include surface and snowpack processes relevant to Greenland's mass balance and surface energy budget. These data provide detailed information on the stratigraphy and physical properties of the near-surface snowpack, offering insight into seasonal evolution and melt-related transformations.\r\n\r\nThe dataset collection includes:\r\n\r\n - Manual snow density - from 1-m snow profiles (two profiles in May, one in August).\r\n\r\n - Permittivity-based snow density - from a dielectric probe applied to the same profiles (two profiles in May, one in August).\r\n\r\n - Manual shear strength - from mechanical shear strength measurements in 1-m profiles (two profiles in May, one in August).\r\n\r\n - Snow specific surface area (SSA) - from field optical methods (two profiles in May, one in August).\r\n\r\n - Manual snow properties - layer identification, hand hardness, and snow grain size and habit (two profiles in May, one in August).\r\n\r\nTogether, these datasets provide a comprehensive view of snow physical properties across the early melt season (May) and peak summer (August), allowing comparisons of density, strength, and microstructural characteristics. The Camp Raven observations complement the broader ICECAPS-MELT suite of measurements by linking surface meteorological and radiative conditions with snowpack evolution on the southwestern Greenland Ice Sheet.\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.",
