Validation of electricity grid distruption by storms

The adjacent folder output contains model output from open-gira, specifically an estimate of the degree of disruption to the Puerto Rican electricity grid in the aftermath of 2017's Hurricane Maria.

See the targets__storm_rNA_s99_n99_2017_0.gpkg and their f_value field for estimates of degree of electricity supply. Where f_value < 1, there has been disruption to supply for that area.

The model has been evaluated for three values of damage threshold -- the wind speed at which infrastructure is deemed to fail: 20, 35 and 50 m/s.

It was run with data characterising the Maria stormtrack, processed into the same format as the synthetic IBTrACS data that open-gira has been designed to operate on (see input for this file).

To plot some of the outputs (target files) see the compare_thresholds.ipynb notebook. An environment.yml file specifies the environment required to run the notebook.

Recreate outputs

To (maybe) recreate this analysis:

• Clone the open-gira repository
• Checkout 63ab3947
• Create and activate a suitable Python environment from the .yml file
• Place input/STORM_DATA_IBTRACS_NA_1000_YEARS_99.txt in results/input/stormtracks/events/constant/NA/
• Move input/run_maria.sh to the root of the open-gira repository and run it
