Snow density and grain size measurements from Snow Micro Pen (SMP) on ice stations PS81/517 and PS81/518 from Weddell Sea, Antarctica, 2013

This dataset contains SnowMicroPen (SMP) measurements on sea ice stations PS81/517 and PS81/518 from Research Vessel Polarstern in the Antarctic Weddell Sea in austral winter 2013 (cruise leg ANT-XXIX/6, AWECS campaign). The SMP surveyed the uppermost approximately 25-30 cm of the snow surface, and...

Description
Summary:This dataset contains SnowMicroPen (SMP) measurements on sea ice stations PS81/517 and PS81/518 from Research Vessel Polarstern in the Antarctic Weddell Sea in austral winter 2013 (cruise leg ANT-XXIX/6, AWECS campaign). The SMP surveyed the uppermost approximately 25-30 cm of the snow surface, and processed output is available at 2.5 mm vertical resolution. The data contains snow density and grain size. Measurements were performed between 2013-07-31 and 2013-08-04. SMP measurements were done in close proximity (approximately 1-2 m distance) of snow pit locations (see Paul et al., 2017), to enable calibration of the instrument. Two perpendicular transects were made in a field that was surveyed using terrestrial laser scanning, to sample the spatial variability of the snow microstructure on sea ice. Further information can be found in Wever et al. (2021).
