SUMMA (Structure for Unifying Multiple Modeling Alternatives)
Required Data
1. precipitation rate [kg m-2 s-1]
2. incoming shortwave radiation [W m-2]
3. incoming longwave radiation [W m-2]
4. air temperature [K]
5. wind speed [m s-1]
6. air pressure [Pa]
7. specific humidity [g g-1]
Data Sources
Spatial Resolution
Flexible
Temporal Resolution
Flexible
File Format
● Forcing must be provided in .nc files, with a time and HRU dimension
Section 2: Features
Strengths and Limitations
● Not limited to a given spatial or temporal resolution
External and Internal Tools
● Python CANDEX package to convert forcing to the required spatial domain (e.g. spatial interpolation
● Python METSIM package for temporal disaggregation, estimating missing forcing variables.

Section 3: Workflow
Model Workflow
1. Download raw forcing data
2. [Optional] construct and/or disaggregate missing forcing data
3. [Optional] re-sample data from native spatial resolution to desired configuration (grid or irregular shapes)
4. [Optional] re-sample data from native temporal resolution to desired time step size
5. Convert forcing data to .nc file with dimensions time and hru.
