Not all models have the same number of scenarios, enesmble members, and
variables. Each individual model needs to be investigated individually.
However, datatool can ignore invalid choices automatically upon job
submission.
The coordinate variables for this dataset are rlon and rlat representing the longitude and latitude points, respectively.
The time-stamps are included in the original files.
This dataset offers downscaled outputs of various climate models. Table below
summarizes the models and relevant keywords that could be used with the
main datatool script:
| # | Model (keyword for --model) |
Scenarios (keyword for --scenario) |
|---|---|---|
| 1 | CanESM5 |
historical, ssp126, ssp245, ssp370, ssp585 |
| 2 | MPI-ESM1-2-LR |

This dataset offers downscaled outputs of various climate models. Table below summarizes the dataset ensemble members for each climate model:
| # | Model (keyword for --model) |

and longitudes from -179.99 to 179.99 covering North America. The resolution is 0.11 degrees (~10km).
The time-stamps are already included in the original files. The dataset offers hourly time-series of climate variables. The following table describes the temporal extent for senarios included in this dataset:
| # | Scenarios (keyword for --scenario) |

| 5 | ssp585 |
2015-01-01 to 2100-12-31 |
Note
Values of the Temporal extent column are the limits for --start-date
and --end-date options with the main datatool script.
This dataset only offers seven climate variables:
- hourly precipitation time-series (surface level),
- hourly temperature time-series (@2m, near-surface level),
- hourly specific humidity time-series (@2m, near-surface level),
- hourly surface pressue time-series (surface level),
- hourly wind speed (@10m, near-surface level),
- hourly shortwave radiation (surface level), and
- hourly longwave radiation (surface level).
