Difference between RH and temperature recorded by each probe with respect to the average from all probes in two different calibration periods: first, from 18th to 21st July 2008 (a: RH; b: temperature) or second, from July 31st to August 28th 2009 (c: RH, d: temperature). Trajectories were smoothed using a moving average with a window size of one day.Back to article page
