# Smoke Window

> Smoke Window helps people compare NOAA HRRR-Smoke modeled near-surface smoke from now through the next 48 hours for lower-48 U.S. locations. It keeps modeled smoke separate from nearby preliminary AirNow AQI observations and reported NIFC WFIGS fires.

## Agent guidance

Use the downloadable local tool when a current structured forecast is required. It rechecks NOAA for the newest complete 48-hour run and downloads all 17 three-hour frames directly on the requesting device. The site does not operate a hosted API or remote MCP server.

Call results “NOAA HRRR-Smoke modeled near-surface smoke.” Do not call them AQI, measured air quality, official health guidance, or a guarantee of clean conditions. AirNow is separate observed context. WFIGS proximity does not prove smoke origin.
