Description
The projected extreme wind risk product captures the projected risks of extreme wind events across the globe using wind speed data. This extreme wind product seeks to identify areas across the globe where historically observed extreme wind events have posed risks to the built environment and human life. This data is intended to be used to assess the projected extreme wind conditions under two future scenarios (SSP2-4.5 and SSP5-8.5) from 2030-2090.
Technical Description
The global Extreme Wind Risk Projection products capture projected risk of extreme wind across the globe using simulated future surface wind speed data. These risk maps reflect the future risk from extreme wind in global land regions at decadal time steps for Shared Socioeconomic Pathway SSP2-4.5. These maps use future CMIP6-based projections of wind speed to calculate likely changes to extreme wind conditions into the future. The spatial scale for this dataset is 11 km/pixel and data is available for the years 2030 - 2090 (where windows centered around the year are used to calculate the projected extreme wind conditions). Extreme wind frequencies (between 0-1) are provided for the combinations of SSP and time horizon.
This dataset contains the following fields:
- extreme_wind_frequency: Frequencies of extreme wind occurrence at pixel locations over the future time period. This looks at the frequencies of extreme wind occurrence at pixel locations over the period of record used for calculation. For instance, a value of 0.5 would indicate that half of the days were under extreme wind conditions for that location. This is a value between 0.0 and 1.0.
- extreme_wind_risk_class: The extreme wind risk classification for each value. Values are integers from 1 to 5 representing the following classes: Very Low Risk (1), Low Risk (2), Moderate Risk (3), High Risk (4), and Very High Risk (5). Values are categorized using the 44th, 67th, 84th, and 94th percentiles of the
- extreme_wind_frequency field, exclusive of '0' values.
