Hydrological Model
CRHM (Cold Region Hydrological Model)
Required Data
1. precipitation,
2. air temperature,
3. relative humidity/vapor pressure,
4. wind speed
5. incoming shortwave radiation (when unavailable model can estimate it).
Data Sources
Station (ECCC, provincial, research site) and Reanalysis data
Spatial Resolution
HRU scale
Temporal Resolution
Sub-daily (ideally hourly)
File Format
Timeseries stored in flat ASCII (.obs)
Section 2: Features
Strengths and Limitations
- Station data are not readily available for all catchments and may contain long gaps in data
External and Internal Tools
- R package (CRHMr) for filling data through interpolation
- R package (Reanalysis) for creating CRHM .obs files from gridded data
TBD_STEPHEN best link possible to R packages
Source Code Availability
- Module code and tools are publicly available with examples
TBD_STEPHEN best link to source code, version number, and tag please.
Section 3: Workflow
Model Workflow
1. Download station data
2. QA/QC (manual/ using CRHMr package)
3. Filling the gaps in data through interpolation/ imputation using CRHMr
4. Create .obs files of forcing timeseries using CRHMr
Notes
Thanks to Prabin for synthesis of this data!
