Extreme Precipitation, Projections, Decadal, Global (v2.0)

Technical Description

The global Extreme Precipitation Projection Risk v2 products capture the projected risk of extreme precipitation across the globe using well-established precipitation indices. These products identify extreme precipitation events characterized by both extreme absolute magnitude and extreme relative to the typical precipitation patterns of a specific location. For instance, while London, UK may experience frequent rain events, they are less common in Phoenix, US. To achieve this, we established thresholds based on relevant scientific literature. These products can be used to assess the future risk from extreme precipitation in global land areas at decadal time steps for Shared Socioeconomic Pathway scenarios SSP2-4.5 and SSP5-8.5.

This dataset contains the following fields:

• extreme_precipitation_frequency: Frequencies of extreme precipitation occurrence at pixel locations over the period of record used for calculation. This looks at the frequencies of extreme precipitation occurrence at pixel locations over the period of record used for calculation. For instance, a 0.5 value would indicate that half of the days were under extreme precipitation conditions for that location. This is a value between 0.0 and 1.0.
• extreme_precipitation_risk_class: The extreme precipitation 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_precipitation_frequency field, exclusive of '0' values.
