Investigation of high resolved snow height measurements at Neumayer Station, Antarctica, 2013
Antarctica is a continent with a strong character. High wind speeds, very low temperatures and heavy snow storms. All these parameters are well known due to observations and measurements, but precipitation measurements are still rare because the number of manned stations is very limited in Antarctic...
