First day of measurements after a warm night

Today, we (with the colleagues from Michigan Technical University, Louisa and Claudia) went up to the flux site tower, about half a mile south of the base camp also to secure clean conditions, to do the daily/weekly/monthly routines of checking and maintaining the instruments. Some of the tasks are removing the rime and snow from the temperature and ozone sensors but also to check the gas cilinder supply, checking the concentration levels and measuring the height of the instruments above the changing snow surface. Recording of the information from all the instruments, which are all stored in a huge warm shed constructed deep into the snow pack is essential for the later interpretation of all these observations. But it is also updating the logbook with information when we have been at the tower and the exact time when we changed the position of some of the ozone sensors. By the way, sleeping in the tent was not too bad, not cold at all having a sleeping bag for surviving -40C and an extra flee sleeping bag to put inside (but you should only not have a sleeping bag claustrofobia), So far for now,
