24	c ATTENTION!! runs are supposed to start with Jan, 1. 1930
25	c (rday=1)
26	c
27	c 27/06/01: Correction: The model always has 360 days per year!
28	c 27/06/01: SO4 concentration rather than mixing ratio
29	c 27/06/01: 10yr-mean-values to interpolate
30	c 20/08/01: Correct the error through integer-values in interpolations
31	c 21/08/01: Introduce flag to read in just one decade
