Greece Subnational Rainfall: Dekadal CHIRPS Precipitation and Forecasts

Dekadal rainfall indicators for Greece aggregated by subnational administrative units, derived from CHIRPS satellite imagery and CHIRPS-GEFS forecasts. Produced by the World Food Programme, the data tracks 10-day, 1-month, and 3-month rainfall totals alongside long-term averages and anomalies as of March 2026.

Use Cases

• Assessing regional drought severity by comparing 3-month rolling rainfall (r3h) against long-term averages (r3h_avg)
• Short-term agricultural planning using 10-day rainfall forecasts (rfh) filtered by the 'forecast' type
• Spatial analysis of precipitation trends across Greece using WFP Pcode administrative units and pixel counts (n_pixels)

Strengths

• Integrates CHIRPS-GEFS short-term forecasts with historical observations
• Uses standardized WFP Pcode references for administrative unit mapping
• Provides 9 distinct rainfall indicators including anomalies and rolling averages

Limitations

• Satellite-derived precipitation estimates may deviate from local station-only data
• Forecast values in the 'type' column are subject to revision as preliminary and final data become available
