<p>We update the total runoff and runoff partitioned from snowmelt from TerraClimate using a modified water balance model that better accounts for baseflow lags in hydrology for use in basin level water supply availability at monthly time scales. These data complement existing TerraClimate 1-d water balance similations, but show much has improved montly correlative skill (median r=0.88) to observed streamflow across watersheds globally watersheds compared with the original method from TerraClimate (median r=0.75). These data can be used to quantify gaps in monthly water demand for downstream water uses including agriculture.</p>
