On the day 30 years ago the Global Runoff Data Centre (GRDC) was established at the German Federal Institute of Hydrology (BfG).

River discharge data collected by the World Meteorological Organization (WMO) in the framework of the “First Global Atmospheric Research Program Global Experiment” in the ‘70s and early ‘80s and a compilation of monthly discharge data collected by UNESCO constituted the initial dataset of approximately 3500 stations.

Operating under the auspices of WMO the database of quality controlled “historical” mean daily and monthly discharge data continued to grow steadily and currently comprises river discharge data of more than 9500 stations from 161 countries.
The exchange of hydrological data and information on a global scale is the principal reason for operating GRDC. National Hydrological and Hydro-Meteorological Services as primary providers of river discharge data and associated metadata and the scientific research community utilising this unique data collection are partners connected by GRDC.

Increasing data supplies and rising numbers of data requests are reflecting a sound relation with data providers and users. This is a good basis for looking ahead with confidence to the continued operation of GRDC in a challenging environment.
