Egypt Subnational Rainfall: Dekadal Indicators and Forecasts

Egypt subnational rainfall indicators provided by the World Food Programme (WFP) using CHIRPS satellite imagery and CHIRPS-GEFS forecasts. The data is aggregated by administrative units and updated every dekad (10 days) to provide current, preliminary, and final precipitation measurements.

Use Cases

• Drought monitoring using the rfq rainfall anomaly column to identify precipitation deficits
• Agricultural planning by analyzing r3h 3-month rolling aggregations for seasonal trends
• Short-term weather risk assessment by comparing rfh forecasts against rfh_avg long-term averages

Strengths

• Uses CHIRPS v2 which integrates satellite imagery with in-situ station data
• Includes standardized Pcode references for administrative units
• Provides n_pixels column to quantify the data density of each aggregate

Limitations

• Satellite-derived precipitation may differ from local rain gauge measurements in specific microclimates
• Data versions (forecast vs final) change throughout the month, requiring careful filtering of the type column
