Double mass curve#

Daily total precipitation in millimeters per day, it is the sum of all forms converted to water-equivalent (millimetres). Daily precipitation does not represent a point measurement but is a modelled, spatially distributed time series that we aggregated to a catchment-average value derived from Nasa Daymet gridded data.

See the summary page on Double Mass Curves for an overview of runoff coefficients at the (sub)sample level to interpret this plot and identify potential data issues and examine spatial patterns.
