(2): Sources of Climate Data

Where can I find climate data?

Hourly climate data which include rain are even harder to find than material data.

IBP offers one year of hourly weather data with WUFI (the file can also be downloaded from the IBP website). These data from 1991 are considered fairly representative for the climate of the Holzkirchen region.
In addition, weather data for 93 locations in Europe, America and Japan are provided with the professional WUFI version.

Another source of hourly weather data for Germany are the Test Reference Years of the German Meteorological Service DWD which represent typical as well as extreme weather situations. Since they are primarily intended for heating and energy consumption investigations, they have no rain data, however, and thus are of only limited usefulness for hygrothermal investigations.

For other possible climate data sources see Sources for Climate Data.

If the situation of a specific object is to be investigated, it may be necessary to measure the weather in-situ anyway.
