Equatorial Guinea: Subnational Rainfall Indicators and Forecasts

Equatorial Guinea subnational rainfall data from the World Food Programme features nine dekadal indicators derived from CHIRPS satellite imagery and GEFS forecasts. Updated multiple times per month as of 2026, the records include precipitation metrics such as 3-month rolling aggregations (r3h) and percentage anomalies (rfq) mapped to standardized administrative units.

Use Cases

• Monitoring agricultural stress by tracking 3-month rainfall anomalies (r3q)
• Validating climate models using the long-term average columns (rfh_avg, r1h_avg, r3h_avg)
• Early warning systems for flooding using 10-day rainfall totals (rfh) and forecasts

Strengths

• Standardized WFP Pcode references for all administrative units
• Nine distinct rainfall indicators including rolling aggregations and anomalies
• Regular update cycle with initial, updated, and final data types

Limitations

• Satellite-derived CHIRPS data may have biases in mountainous or coastal regions
• Aggregation is dependent on the number of input pixels (n_pixels), which varies by unit size
