Snow density profiles from Neumayer station
This is a collection of shallow snow density data sets from research station Neumayer II, Neumayer III and the Kottas traverse between Neumayer, Kottas camp and Kohnen station. The original snow density data are available as Excel and txt files and as density-depth profiles in png format. The data w...
