Honduras Subnational Rainfall: Dekadal Indicators and CHIRPS Forecasts

Honduras subnational rainfall indicators from the World Food Programme provide 10-day, 1-month, and 3-month precipitation metrics derived from CHIRPS v2 satellite imagery and GEFS forecasts. The data covers administrative units identified by Pcodes and includes historical anomalies and long-term averages updated up to six times per month.

Use Cases

• Drought monitoring using the 3-month rainfall anomaly percentage (r3q) to identify moisture deficits
• Agricultural season tracking by comparing current 10-day rainfall (rfh) against long-term averages (rfh_avg)
• Spatial analysis of precipitation trends across specific administrative units using WFP Pcodes

Strengths

• Includes 9 distinct rainfall indicators including 3-month rolling aggregations
• Provides Pcode references for direct joining with other humanitarian administrative datasets
• Contains data quality metadata via the n_pixels column indicating input density

Limitations

• Satellite-derived precipitation estimates may deviate from ground-truth rain gauges in complex mountainous terrain
• Temporal lag exists as final validated products only replace preliminary ones mid-month
