(a, c) Plot of PM10 concentration, temperature, and humidity as well as the regularized profile of PM10 concentration as in (9): outdoor concentration (a, b); indoor concentration (c, d). PM10 concentration has been multiplied by 50 in order to show all the data in the same figure. (b, d) The same measures as in (a, c), but data have been preregularized before using them in (9). Cumulative summation has been used for preregularization.
