Extreme Precipitation - Current Risk, Global (v1.0)

Technical Description

The Current Extreme Precipitation Risk product captures the near-term risk of extreme precipitation across the globe using proprietary forecasts of precipitation totals, as well as historically observed statistics of precipitation at the same location. These products seek to identify areas across the region which are forecasted to have anomalously high precipitation totals, looking at both the likelihood of precipitation occurring as well as the intensity of the event. Extreme precipitation index values are calculated and then classed into one of five risk categories.

This Current Risk layer looks at the maximum of the daily extreme precipitation conditions across the globe for the next 1-3 days.

The following Extreme Precipitation Risk classes are used to classify the extreme precipitation index values:

• Very Low (0) : Very low risk of extreme precipitation events over the current time period. Extreme precipitation index values are less than 0.3.
• Low (1) : Low risk of extreme precipitation events over the current time period. Extreme precipitation index values are between 0.3 and 0.5.
• Moderate (2) : Moderate risk of extreme precipitation events over the current time period. Extreme precipitation index values are between 0.5 and 0.7.
• High (3) : High risk of extreme precipitation events over the current time period. Extreme precipitation index values are between 0.7 and 0.9.
• Very High (4) : Very high risk of extreme precipitation events over the current time period. Extreme precipitation index values are greater than 0.9.

This dataset contains the following fields:

• extreme_precipitation_risk_class: The extreme precipitation risk classification for each pixel location. The values are integers from 0-4 representing the extreme precipitation classes of Very Low (0), Low (1), Moderate (2), High (3), and Very High (4).
