high-resolution, daily hindcast (1990-2021) data of Alaskan river discharge and temperature

These data are describe in the paper “A high-resolution, daily hindcast (1990-2021) of Alaskan river discharge and temperature from coupled and optimized physical models” that was submitted to WRR. There are three files within this directory.

1. River_Segment_Locations.csv
2. Historic_River_Discharge.zip
3. Historic_River_Temperature.zip

A detailed description of each document is as follows.

River_Segment_Locations.csv: Contains a list of all the river segment vectors used in the study. For a brief description of each column, see below.

1. COMID: The unique identifier for each river segment
2. Latitude: The centroid latitude of each river segment in decimal degrees
3. Longitude: The centroid longitude of each river segment in decimal degrees
4. Outlet_COMID: The unique identifier of the basin outlet. This ID will be used to select files within the .zip files.

Historic_River_Discharge.zip: Contains the daily river discharge data from January 1990 - September 2021. Files are broken down by basin, denoted by the Outlet_COMID, and the calendar year. Each file is a netCDF file that contains the river discharge (IRFroutedRunoff) in m3 s-1.

Historic_River_Temperature.zip: Contains the daily river temperature data from January 1990 - September 2021. Files are broken down by basin, denoted by the Outlet_COMID, and the calendar year. Each file is a netCDF file that contains the water temperature (T_stream) in degrees Celsius, the air temperature (T_air), and the headwater temperature (T_headwater) in degrees Celsius.
