masaya
Active lava lake monitoring at Masaya volcano, Nicaragua, using Sentinel-2 SWIR and NBR. Masaya hosts one of the planet's few persistent lava lakes, active in the Santiago crater since December 2015. The primary signal here is the continuous B12 SWIR thermal anomaly from the active-lava-mask layer, which tracks the lake's persistent thermal emission; dNBR is retained for consistency with the family but is secondary because no large discrete flow field has developed outside the crater rim.

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
