Eritrea Subnational Dekadal Rainfall Indicators and Forecasts

Dekadal rainfall indicators for Eritrea aggregated by subnational administrative units, produced by the World Food Programme (WFP) using CHIRPS satellite imagery and CHIRPS-GEFS forecasts. It tracks 10-day, 1-month, and 3-month rainfall totals alongside long-term averages and percentage anomalies. The records are updated frequently to transition from initial forecasts to final validated observations.

Use Cases

• Assessing drought severity by comparing 3-month rainfall anomaly (r3q) across administrative units
• Short-term agricultural planning using 10-day rainfall forecasts (rfh) filtered by the type column
• Historical trend analysis using long-term averages (rfh_avg) to establish baseline precipitation patterns

Strengths

• Uses CHIRPS version 2 combining satellite and in-situ station data
• Includes 9 distinct rainfall and anomaly indicators
• Standardized subnational Pcode references for administrative units

Limitations

• Satellite-derived estimates may vary from local rain gauge measurements
• Recent data entries are subject to revision as they transition from forecast to final status
