Uruguay Subnational Rainfall: Dekadal Indicators and Forecasts

The World Food Programme provides dekadal rainfall indicators for Uruguay aggregated by subnational administrative units using CHIRPS v2 satellite imagery and CHIRPS-GEFS forecasts. The dataset tracks 10-day, 1-month, and 3-month rainfall totals, long-term averages, and percentage anomalies. Records are updated six times per month to transition from predictive forecasts to finalized observations.

Use Cases

• Drought monitoring using the 3-month rainfall anomaly (r3q) to identify moisture deficits across subnational units
• Agricultural yield forecasting by comparing current 10-day rainfall (rfh) against long-term averages (rfh_avg)
• Short-term risk assessment by filtering the type column for forecast values to predict upcoming precipitation

Strengths

• 9 distinct rainfall indicators including rolling averages and anomalies
• Standardized WFP Pcode references for administrative units
• Frequent update cycle transitioning from forecast to final data

Limitations

• Satellite-derived estimates may deviate from local station-only measurements in specific microclimates
• Recent records are subject to revision as they move from forecast to final status
