What a cloud calibration gives you
Two of our calibrated SWAT+ models on the Chesapeake Bay hub, each fitted to its own USGS gauge. Bixler Run, Pennsylvania, 2012 to 2015: daily NSE 0.75, KGE 0.79, and 2.3 % more water than the gauge measured. Lycoming Creek, 2005 to 2017: daily NSE 0.63, and 4.8 % less. These are verification years, and each run's water balance closes. Cloud calibration is pay as you go on every plan, including Free, with the estimated cost shown before you launch.

Here are two of our calibrated models, on the Chesapeake Bay hub, each fitted to its own USGS gauge.
Bixler Run, in Pennsylvania, 2012 to 2015. Grey is the gauge, blue is the calibrated model. These are verification years: the calibration was fitted to other years.
Over those years: daily NSE 0.75, KGE 0.79, and the model simulates 2.3 percent more water than the gauge measured.
The same run's water balance closes: the year's precipitation is accounted for by evapotranspiration, surface runoff, lateral flow, percolation and the change in soil water.
Lycoming Creek, 2005 to 2017, also verification years: daily NSE 0.63, and the model simulates 4.8 percent less water than the gauge measured. Its water balance closes too.
Cloud calibration is pay as you go, on every plan including Free. Buy calibration credit in fifty, one hundred or two hundred dollar packs, and you see the estimated cost before you launch.
