Mozambique Subnational Rainfall: Dekadal Indicators and Forecasts

Mozambique subnational rainfall indicators provided by the World Food Programme (WFP) based on CHIRPS satellite imagery and CHIRPS-GEFS forecasts. The data covers 10-day (dekadal) periods and includes rolling 1-month and 3-month aggregations alongside long-term averages. Records are aggregated by administrative units and updated multiple times per month to transition from forecasts to final observations.

Use Cases

• Drought monitoring using the 3-month rainfall anomaly percentage (r3q) to identify regions with precipitation deficits
• Agricultural planning by comparing current 10-day rainfall (rfh) against long-term averages (rfh_avg)
• Flood risk assessment by analyzing 1-month rolling aggregations (r1h) for specific administrative units

Strengths

• 9 distinct rainfall indicators including rolling averages and anomalies
• Standardized WFP Pcode references for administrative unit joins
• Explicit data status tracking via the 'type' column

Limitations

• Satellite-derived estimates may vary from local rain gauge measurements
• Temporal resolution is restricted to 10-day dekads rather than daily data
• Geographic scope is limited strictly to Mozambique
