How it works · Envision

The Ingest layer is responsible for collecting observations from FIRMS, NWS, NHC, JTWC, Open-Meteo, ECMWF, and AIFS; every 30 minutes to 12 hours (per source), it normalizes payloads into the signals table and retains GDACS ground truth for scoring.

Data sources & attribution

NASA FIRMS — active fire detections (MODIS + VIIRS)
NWS Alerts API — fire-weather watches and warnings
NHC CurrentStorms.json — Atlantic and East Pacific cyclone advisories
JTWC — Western Pacific cyclone advisories
Open-Meteo — fire-weather indices
ECMWF Open Data — fire-weather grids
AIFS (ECMWF) — AI forecast grids and derived features
GDACS — global disaster ground truth (evaluator only)
GeoNames cities5000 — populated places for landfall detection

The Forecast layer is responsible for running detection skills on each skill cadence; every cycle, it clusters and interprets signals, writes probabilistic forecasts (capped at 0.85), and attaches LLM reasoning for the map.

The Evolve layer is responsible for improving the skill library; every 24 hours, it reads live Brier scores, mutates skill code, backtests candidates, shadow-evaluates on live traffic, and queues proposals for human review before anything reaches the public map.
