Figure 3: (a) The response of the environment system to the outside humidity (thick line). When a level of 70% on the rising edge is passed, the roofs are closed (note that the bay humidity, dot-dashed, stays roughly constant thereafter. Reopening of the building is allowed, once the humidity has dropped below 60% and remained at that level for at least two hours. (b) Prediction of inversion layer breakdowns. The thick line is the measured relative humidity. The 100-second extrapolations of various extrapolators are superimposed onto the true measurement. The true development of the humidity could be foreseen by all of the extrapolators. Note the delayed onset of the humidity rise of the extrapolated to the true values. The extrapolation could not predict that a sharp rise will start to occur, but the goal to predict the height of the humidity rise is well matched.
