National Water Model 25 Year Retrospective Simulation now available

Now available on the Environmental Data Commons is the National Water Model 25 Year retrospective simulation v1.2 (Jan 1, 1993 - Dec 31, 2017). It contains:

  • A reanalysis rather than a reforecast (forcing different than real-time runs)

  • Output fields are fewer and less frequent than real-time to conserve space

  • Provides historical context to current conditions

  • Can be used to infer flow frequencies and perform temporal analyses

  • 584,384 objects, 21.7 Tb in size, with hourly streamflow output and 3-hourly land surface output
