The data were summarized from snowmelt, rainfall and total runoff data from TerraClimate (<a href="https://doi.org/10.5061/dryad.vx0k6dk2h" target="_blank">https://doi.org/10.5061/dryad.vx0k6dk2h</a>).

The fraction can be converted to the day of the month by multiplying it by the number of days in the month. A value of 1.3 would correspond to January 9, or a value of 9.7 would correspond to September 21.</p>
