Abstract
We introduce a new Arctic daily discharge data set covering 17 gauges in 3 large drainage basins in the Russian pan-Arctic (Ob, Yenisey and Lena). All gauges are under significant influence of reservoir regulation. The data set includes two types of discharge data: 1) observed daily discharge values compiled in the State Hydrological Institute, Russia from official sources and 2) modeled “naturalized” daily discharge The “naturalized” discharge means discharge values with excluded human impact.The data can be used in hydro-climatological analysis to understand interactions between climate and hydrology. A specially developed Hydrograph Transformation Model (HTM) was used to eliminate effects of reservoirs and other human impact from discharge records.Data
Data are available in three files, the station attributes file which contains information about each station and the data files containing observational and “naturalized” daily discharge values: Station attributes file: tab delimited ASCII text file with headersData file (observed daily values): tab delimited ASCII text file with headers
Data file (“naturalized” daily values): tab delimited ASCII text file with headers
Description of Fields
Station attributes
The station attribute file has 1 header line and 19 data lines with one line per station and 13 fields of data: data:Field Description ===== =========== PointID Unique station identification number from R-ArcticNet Code Station code from RosHydromet and used by R-ArcticNet, Name Station Name, typically "[River] At [Location]" Lat Latitude of station in decimal degrees Long Longitude of station in decimal degrees DArea Drainage area of drainage basin (km2) DArea_Effective Total contributing area of basin (km2) Hydrozone Name of large river basin Gauge_altitude Height of gauge benchmark above Baltic Sea level DistanceToOulet Distance to sea or to confluence with main MaxOfYear Last year with data MinOfYear First year with data Natur_Period Period with naturalized daily discharge data available
