Micronesia Subnational Rainfall Indicators and Anomalies by Dekad

Micronesia subnational rainfall indicators provided by the World Food Programme, derived from CHIRPS v2 satellite imagery and CHIRPS-GEFS forecasts. The data tracks 10-day (dekadal) intervals including rolling 1-month and 3-month aggregations alongside long-term averages for administrative units.

Use Cases

• Monitoring drought conditions using the rfq (rainfall anomaly) and r3q (3-month anomaly) columns
• Comparing current precipitation against historical norms using rfh_avg and r1h_avg
• Distinguishing between predicted and actual rainfall events using the type column

Strengths

• Integrates CHIRPS v2 satellite data with in-situ station records
• Includes 9 distinct rainfall and anomaly indicators per dekad
• Standardized Pcode references for subnational administrative units

Limitations

• Forecast data is subject to revision as preliminary and final products are released
• Spatial accuracy is dependent on the n_pixels count for smaller administrative units
