Observed Daily Discharge
Figure 1 provides an overview of European catchments where observed daily discharge (=river runoff) data are available in the years 1980, 1990, 2000 and 2010. The colors indicate the number of years within these four years, when discharge data are available. Table 1 lists the rivers (globally) and the most downstream stations for which such data are available. In addition, the available time period, the geographical station coordinates and the respective catchment area are provided. Most of the data were obtained from the Global Runoff Data Centre (GRDC) indicated by the GRDC station No. In case the No. is negative or a missing value (-9999.), the data are obtained from other sources that are listed here.
Figure 2 shows the analogous information on available discharge data for the whole globe.
Info on storage location upon request
Due to data policies of GRDC, the data are not directly publicly available. GRDC provides data free of charge after agreeing to its data policies. Members of Hereon may access the data upon request.
Data format
The data are stored in ASCII files that comprise two columns, the date and the discharge data in m³/s. Missing values are indicated by -9999.
File names are constructed as: <rivertag>_7010000<station tag>_<start year>-<end year>.txt
| Tag | Explanation |
|---|---|
<rivertag> | Tag identifying the river and comprising 3-5 characters that is listed in Table 1. |
| <station tag> | Primary station tag: rs (first appearance of river in Table 1) If there is more than one station, further stations receive tags r2, r3, ... according to their sequence of appearance in Table 1. |
| <start year> | First year with daily data (Column 'Start' in Table 1). |
| <end year> | Last year with daily data (Column 'End' in Table 1). |
