Example

Date,P,E0,Qo,T
1975-03-01,7.67,0.102,0.63,-3.75
1975-03-02,2.26,0.0,0.58,-5.7

1975-03-04,0.0,0.0,0.49,-10.56

Notes

  • All values should be in consistent units (mm/day for water fluxes)
  • Missing temperature data disables snow modeling for the catchment
  • The available date range is automatically detected from the file
  • A warmup period (default 3 years) is used before the analysis period
