ambrym
Active lava lake monitoring and eruption mapping at Ambrym volcano, Vanuatu, using Sentinel-2 SWIR and NBR. Ambrym is a basaltic caldera that hosted persistent lava lakes at Marum and Benbow craters until a December 2018 submarine dyke intrusion drained them abruptly. The recipe captures the lava-lake era and its sudden end; B12 SWIR tracks the lake thermal signal through near-constant tropical cloud cover. The active-lava-mask layer is the primary signal for the lake period, while dNBR documents the caldera floor change following drainage.

The contract
Read from this recipe's own declarations — parameters:,
outputs:, requires:, and the ops its layers name. Not from its
style blocks and not from any benchmark: a colour ramp is not a contract, and a measured
run is evidence about one AOI rather than a domain.
Parameters
The legacy dialect has no typed parameter schema. Read the folia.yaml for what this recipe takes; nothing here can type-check it.
Outputs
| output | kind | layer | what it is |
|---|---|---|---|
primary |
not declared | ['result/lava-flow-extent', 'result/dnbr-severity'] |

show_your_work |
not declared | ['compute/nbr', 'compute/active-lava-mask'] |
Capabilities it requires
The legacy dialect has no requires: block.
Where it runs
- Browser preview does not run here compute/active-lava-mask: layer type "raster_timeseries" is not one folia-view parses; compute/cloud-masked: layer type "raster_timeseries" is not one folia-view parses; compute/dnbr: layer type "raster_timeseries" is not one folia-view parses; and 7 more
- Local CLI (folia run) runs here runs locally through the legacy (no spec_version) parser
- Operated fleet (POST /plan, /run) runs here legacy dialect: a lock binds by the cut's layer names, not by digest
