Observations CSV¶
Daily hydrometeorological observation data for a catchment.
File Naming¶
Example: Au Saumon_Observations.csv
Format¶
Standard CSV with header row. Date format must be YYYY-MM-DD.
Required Columns¶
| Column | Description | Units |
|---|---|---|
Date |
Observation date | YYYY-MM-DD |
P |
Precipitation | mm/day |
E0 |
Potential evapotranspiration | mm/day |
Qo |
Observed streamflow | mm/day |
Optional Columns¶
| Column | Description | Units | Required For |
|---|---|---|---|
T |
Mean daily temperature | °C | Snow modeling (CemaNeige) |
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
