South Sudan: Subnational Dekadal Rainfall Indicators and Anomalies

Delivering dekadal rainfall indicators for South Sudan aggregated by subnational administrative units, produced by the World Food Programme using CHIRPS v2 and CHIRPS-GEFS data. It tracks 10-day, 1-month, and 3-month rainfall measurements alongside long-term averages and anomalies.

Use Cases

• Assessing drought severity by comparing 3-month rolling rainfall (r3h) against long-term averages (r3h_avg)
• Analyzing regional climate trends using the rainfall anomaly percentage (rfq) across different Pcode units
• Evaluating forecast accuracy by comparing 'forecast' values against 'final' values in the type column

Strengths

• Includes 9 distinct rainfall indicators including rolling aggregations and anomalies
• Standardized geographic referencing using WFP Pcodes for subnational units
• High temporal resolution with updates occurring six times per month

Limitations

• Relies on satellite-derived estimates which may deviate from ground-based rain gauge measurements
• Statistical representativeness varies by unit size as indicated by the n_pixels column
