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 headers

Data 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

Data file

The data files has 1 header line and 36952 data lines for observed discharge and 25606 lines for “naturalized“ discharge with one line per station-year-day.
