Georgia Subnational Rainfall: Dekadal Indicators and Forecasts

Georgia subnational rainfall indicators provided by the World Food Programme, featuring dekadal data derived from CHIRPS v2 satellite imagery and GEFS forecasts. The dataset tracks precipitation amounts, rolling averages, and anomalies across administrative units identified by Pcodes, with updates occurring six times per month.

Use Cases

• Drought monitoring using the rfq column to identify regions with significant precipitation deficits
• Agricultural planning by comparing current 3-month rolling rainfall (r3h) against long-term averages (r3h_avg)
• Early warning systems utilizing the type column to distinguish between forecasted rainfall and actual observed precipitation

Strengths

• Blends satellite imagery with in-situ station data via CHIRPS v2
• Provides 9 distinct rainfall indicators including rolling 3-month anomalies
• Standardized subnational Pcode references for administrative units

Limitations

• Satellite-derived precipitation may deviate from ground-truth in complex topography
• Final validated observations lag by up to 45 days from the initial forecast period
