Data Formats

HOLMES uses CSV files for input data and exports results in both CSV and JSON formats.

Input Files

Input data files must be placed in the src/holmes/data/ directory. Each catchment requires:

File Required Description
<Catchment>_Observations.csv Yes Daily hydrometeorological observations
<Catchment>_CemaNeigeInfo.csv No Snow model configuration (required for CemaNeige)
<Catchment>_Projections.csv No Climate projection data

The catchment name in the filename determines how it appears in the application.

Export Files

HOLMES can export results from calibration, simulation, and projection pages. See Exported Files for detailed format specifications.

Page Files Format
Calibration Parameters, results, timeseries JSON, JSON, CSV
Simulation Results, timeseries JSON, CSV
Projection Timeseries, results CSV, CSV
