Bolivia Subnational Rainfall Indicators and CHIRPS-GEFS Forecasts

Giving access to dekadal rainfall indicators for Bolivia's subnational administrative units, produced by the World Food Programme using CHIRPS v2 satellite imagery and CHIRPS-GEFS forecasts. It tracks nine specific metrics including 10-day, 1-month, and 3-month rainfall totals, long-term averages, and percentage anomalies. The data is updated on a recurring cycle to transition from initial forecasts to final observations.

Use Cases

• Drought monitoring by analyzing the rainfall anomaly percentage (rfq) across different Bolivian departments
• Agricultural planning by comparing current 3-month rolling aggregations (r3h) against long-term averages (r3h_avg)
• Forecast validation by comparing values labeled as 'forecast' in the type column against subsequent 'final' observations

Strengths

• Includes long-term averages (rfh_avg) for baseline climate comparison
• Uses standardized WFP Pcode references for administrative unit joins
• Provides pixel counts (n_pixels) to indicate the data density of each aggregate

Limitations

• Relies on satellite-derived estimates which may deviate from ground-based station measurements
• Frequent data overwriting occurs as forecasts are replaced by preliminary and then final products
