SnowEx23 MAR23 IOP Computed Tomography Snow Microstructure V001

This data set characterizes snow microstructure for 11 snow pits from the SnowEx 2023 NASA field campaign Intensive Observation Period (March 2023) using microcomputed tomography (micro-CT). Included with this data set are two- and three-dimensional microstructural analysis of snow samples, black and white binary images of each sub-sample scan, and raw instrument data. Containers of snow were collected at 6 snow pits in approximately 17 cm intervals. There were approximately 5-8 discrete containers per pit and each container had an ~1-2 cm overlap with the sample below. A 6-cm section of snow was dissected from each container of snow, which were analyzed in ~2 cm sub-sections. Each sub-section was scanned in three intervals using a micro-CT instrument. The three interval scans comprise multiple slices and were combined into the reconstructed final scan used for calculating the snow microstructural data.
