Data files

a2s_8_parameter_values.csv

This file contains the values of the calibrated parameters a₁ to a₈ for the 8-parameter version of air2stream for each of the 23 hydrometric stations used in the analysis.

stn_hyd_reg.csv

This file contains the following information for each hydrometric station used in the analysis:

·       Water Survey of Canada (WSC) station number (station_number)

·       hydrologic regime (regime)

·       Water Survey of Canada station name (station_name)

·       regulation status (status)

ts_all_58.csv

This file contains daily time series of the input data and simulated and observed water temperatures for each of the 23 hydrometric station.

·       station_number - WSC station number

·       year, month, day - date

·       ta - daily mean air temperature

·       tw_obs - daily mean observed water temperature (°C)

·       tw_sim_8 - daily mean water temperature simulated by the 8-parameter version of air2stream (°C)

·       q - mean daily streamflow (m³s^-1)

·       period - calibration/validation

·       date - date in yyyy-mm-dd format

·       tw_sim_5 - daily mean water temperature simulated by the 5-parameter version of air2stream (°C)

Scripts
