mate and are thus suited for the most varied areas of application and for manifold scientific 
studies. 
The phenological monitoring data of DWD is not exchanged internationally, since there are 
no agreements in place for the exchange of such data between the Meteorological Services 
In addition, such monitoring is carried out in only a few countries. 
In 1957 a European network of International Phenological Gardens (IPGs) was established. 
This network was coached by DWD until 1995. Since then the responsibility is with the Hum 
boldt-University in Berlin 21 .
