Djibouti Subnational Rainfall: Dekadal Indicators and CHIRPS Forecasts

Djibouti subnational rainfall indicators are provided by the World Food Programme (WFP) based on CHIRPS satellite imagery and GEFS forecasts. The data tracks 10-day, 1-month, and 3-month precipitation totals alongside long-term averages and anomalies for drought and flood monitoring. Updates occur six times per month to transition from short-term forecasts to final validated observations.

Use Cases

• Drought monitoring by analyzing the 3-month rainfall anomaly percentage in the 'r3q' column
• Agricultural season planning using long-term averages from 'rfh_avg'
• Flood risk assessment by monitoring 10-day rainfall totals in 'rfh'

Strengths

• Uses WFP Pcode references for standardized subnational mapping
• Includes 9 distinct rainfall indicators including rolling averages and anomalies
• Provides a clear data lifecycle from forecast to final validated product via the 'type' column

Limitations

• Satellite-derived estimates from CHIRPS may vary from local ground station measurements
• Geographic scope is restricted to Djibouti
• Temporal resolution is limited to 10-day dekadal blocks rather than daily totals
