description	Define scheduled and custom EO data pipelines with optional pre/post-processing and DHIS2-ready outputs.

EO Pipeline Orchestration

Use this skill when

• Creating recurring ingestion workflows
• Adding custom pre/post-processing pipeline steps
• Designing orchestration handoffs (Airflow/Prefect)

Canonical pipeline stages

1. Discover dataset and validate metadata
2. Extract data for time/area window
3. Cache source/intermediate artifacts as files when needed
4. Transform and harmonize units/CRS
5. Aggregate to org unit geometries
6. Optional post-process (e.g., consecutive rainy days)
7. Produce import-ready output for DHIS2
8. Trigger import or publish for downstream ingestion

Orchestration guidance

• Treat each stage as an idempotent task where possible
• Persist execution metadata and lineage
• Use retries/backoff for transient provider failures
• Surface execution status and partial failure details via API
• Use dhis2eo for EO/climate processing tasks inside pipeline stages
• Use dhis2-python-client for DHIS2 import/export interactions
• Push processed outputs to DHIS2 via Web API as the default load path
• Use DHIS2 Data Store for pipeline/configuration metadata where appropriate
• Promote reusable orchestration helpers to upstream libraries when they are broadly applicable beyond eo-api

Data integrity checks

• Nodata handling rules are explicit
• CRS mismatches are detected and resolved deterministically
• Aggregation method and temporal windows are logged

MVP constraints

• Prefer simple, inspectable DAGs over highly dynamic graphs
• Prioritize reliable daily scheduled runs for climate and population flows
