Bermuda Subnational Rainfall Indicators and CHIRPS-GEFS Forecasts

Dekadal rainfall indicators for Bermuda's subnational units are provided by the World Food Programme using CHIRPS v2 satellite imagery and CHIRPS-GEFS forecasts. The data includes 9 specific metrics such as 10-day rainfall (rfh), rolling 3-month aggregations (r3h), and anomaly percentages (rfq) for each administrative area.

Use Cases

• Assessing current moisture deficits by comparing the 3-month rolling aggregation (r3h) to its long-term average (r3h_avg)
• Short-term flood risk modeling using the 10-day rainfall forecast (rfh) filtered by the type column
• Spatial analysis of precipitation trends across Bermuda using the Pcode administrative identifiers

Strengths

• Integrates CHIRPS-GEFS short-term forecasts with historical CHIRPS v2 observations
• Includes 9 distinct rainfall and anomaly indicators including rolling 3-month aggregations
• Standardized using WFP Pcode administrative references for geospatial interoperability

Limitations

• Small administrative units may rely on a low number of input pixels as indicated by the n_pixels column
• Recent records are subject to two stages of revision (preliminary and final) before being considered historical fact
