Ukraine Subnational Rainfall: Dekadal Totals and Anomalies

Ukraine subnational rainfall indicators are provided in 10-day (dekadal) increments by the World Food Programme using CHIRPS v2 and CHIRPS-GEFS satellite data. The data includes precipitation totals, long-term averages, and percentage anomalies for administrative units identified by Pcodes.

Use Cases

• Assessing agricultural drought by monitoring 3-month rainfall anomalies (r3q)
• Short-term crop planning using 10-day rainfall forecasts (rfh) filtered by the type column
• Historical climate trend analysis using long-term averages (rfh_avg) at the subnational level

Strengths

• Standardized Pcode references for subnational administrative units
• Integration of CHIRPS-GEFS for short-term forecasting
• Explicit data versioning via the 'type' column

Limitations

• Satellite-derived estimates may vary from local ground-station measurements
• Temporal resolution of 10 days may obscure sub-dekadal extreme weather events
