HDX HAPI: Subnational Rainfall Indicators for Humanitarian Response

HDX Humanitarian API (HAPI) provides this standardized rainfall indicator dataset, sourced from the World Food Programme (WFP) for the current year. It covers subnational administrative levels (Admin 1 and 2) across global humanitarian contexts to support automated decision-making workflows.

Use Cases

• Monitoring precipitation levels at the Admin 2 level to trigger humanitarian aid in HRP countries
• Automating climate visualizations using standardized HXL tags for cross-dataset joins
• Identifying rainfall anomalies within the current year to assess immediate food security risks

Strengths

• Standardized HXL tags for interoperability
• Granular Admin 2 coverage for HRP countries
• Transparent error and warning reporting per row

Limitations

• Temporal scope restricted to the current year
• Geographic bias towards HRP/GHO countries for granular data
• Presence of incomplete rows marked with errors
