Argentina Subnational Rainfall: Dekadal Indicators and Forecasts

Dekadal rainfall indicators for Argentina's subnational administrative units, derived from CHIRPS v2 satellite imagery and CHIRPS-GEFS forecasts. Produced by the World Food Programme (WFP), the data tracks 10-day, 1-month, and 3-month rainfall totals and anomalies. Updates occur six times per month to transition from forecasts to final observations.

Use Cases

• Drought monitoring using the 3-month rainfall anomaly percentage (r3q) to identify moisture deficits
• Agricultural planning by comparing current 10-day rainfall (rfh) against the long-term average (rfh_avg)
• Forecast validation by comparing 'forecast' values in the type column against subsequent 'final' observations

Strengths

• 9 distinct rainfall indicators including rolling 1-month and 3-month aggregations
• Standardized WFP Pcode references for subnational administrative units
• Includes n_pixels column to quantify the spatial data density for each unit

Limitations

• Satellite-derived estimates (CHIRPS) may vary from local rain gauge measurements
• Data is subject to revision as it moves from forecast to preliminary and final status
