Custom STAC (SpatioTemporal Asset Catalog) extensions for Earth System Model output data.

Reference extensions in your STAC items/collections via their schema URLs:

{
  "stac_extensions": [
    "https://esm-tools.github.io/stac-extensions/hpc/v1.0.0/schema.json",
    "https://esm-tools.github.io/stac-extensions/namelist/v1.0.0/schema.json",
    "https://esm-tools.github.io/stac-extensions/paleo/v1.0.0/schema.json"
  ]
}

These extensions are automatically applied when scanning files with esm-catalog:

# Scan experiment output - extensions applied automatically
esm-catalog scan /work/experiment/outdata --db catalog.duckdb

# Serve via STAC API
esm-catalog serve catalog.duckdb

The extensions enable rich filtering via CQL2 queries in STAC Browser:

• Filter by storage tier (hot/warm/cold)
• Search by simulation parameters (timestep, CO2 level)
• Find paleoclimate simulations by geological period

• ESM-Tools - Earth System Model workflow manager
• esm-catalog - STAC-based catalog for ESM output
• STAC Spec - SpatioTemporal Asset Catalog specification
• stac-fastapi - STAC API implementation
