Are there more recent weather data available? The copy of WUFI I downloaded still has those of 1991.
'Recent' weather data would probably not be very useful to you. It is more important to have weather data which are either known to be typical for a specific location or which repesent defined critical conditions (e.g. for design purposes). We consider 1991 to be a fairly typical year for Holzkirchen. 'Critical' weather data, i.e. one particularly cold year and one particularly warm year, are in preparation and will be made available as two 'Hygrothermal Reference Years'.
