Hydrological study in the Niger River Basin: For a streamflow study in the Niger river basin, time series of daily discharge data, between
1981 and 2010, longer then 15 years, at stations on the rivers in the Niger river basin are requested. As far as available information should be provided about missing values.
• find extent and temporal resolution of time series, e.g. 1981-2010, 15, daily, …
• f... missing value information of the time series, e.g. percentage of missing values.
• f... the hydrologic variable of which time series are avaiable, e.g. discharge.
• f... the hydrologic process characterised by the variable, e.g. streamflow.
• f... the river characterised by the variable, e.g. Benue river.
• f... the basin represented by the Benue river, e.g. Niger basin.
A list, and a map, of all stations in the Niger river basin should be provided comprising the available time series of daily data between 1981 and 2010 with a minimum length of 15 years which enables the user to identify a station of interest and select the time series by percentage of missing values.

are provided in automated way. As far as available information should be provided how the data values are aggregated and about the instrument or method used for the value determination.
• find extent and temporal resolution of time series, e.g. daily
• f... options to transfer time series, e.g. semi-automated transfer, protocols, …
• f... aggregated data value compiled in the time series, e.g. aggregation interval.
• f... the hydrologic variable of which time series are available, e.g. discharge.
• f... determination of discharge values, e.g. ADCP, float gauge, rating.
• f... the station for which discharge data are available, e.g. 26900400 (Cochem).
• f... the river on which 26900400 is located, e.g. Moselle.
• f... the basin represented by the Moselle river, e.g. Rhine basin.
A list, and a map, of all stations in the Rhine basin should be provided comprising the available time series of daily data which enables the collecting data center to identify a station of interest by data transfer mode, and select the time series by data aggregation and the value determination.
