Embers, one line per spotting source: from a burning cell with a maximum spot distance to where its farthest ember lands (FlamMap's maximum spot distance and direction under the run's wind, not the engine's random draws). `minutes` when the source burned, `distanceMeters`, `fireType` 1 surface / 2 passive crown / 3 active crown at the source, `landingMinutes` when the fire reached the landing, `spotFire` true when the landing was outside the fire at the time (worked out in DuckDB against the arrival table). The longest in each part of the fire when there are more than a map can draw. Written by each run of the fire simulation whose output file is "Example Simulation: Long Beach Peninsula (2026-11-03 19:48)".
What you upload. Files are the raw material — run a job against one to turn it into a table or a tile.

Each upload of this file is a version. Jobs run against a specific one, so older versions are kept.
Jobs turn this file into something the map can draw — a parquet table, or GeoTIFF tiles.
Re-run a job on a timer, for data that changes at the source — a nightly feed, a weekly extract.
