We are playing in a ,,cat and mouse'' with the weather. Soon after we started measurements on so far the most northern section EX, we had to stop due to bad conditions and ran south to the EB2. I think everything that could break down, broke down. Even the elevator tried to get out of the control but we have great guys that handle with it, with everything as so far. ,,What can't kill you, it makes you stronger''. This bad conditions, the wind I mean, are great for aerosols thus devices describing physical and chemical characteristics work well. Regards, Agnieszka.
