Who uses LR-x® and what for

The same plume and wind field models serve very different jobs. Pick yours.

Plume modeling for hazmat response teams

Run ALOHA plume models over a 3D wind field from a tablet while en route, and arrive with a threat zone already on the map.

  • Start a model from the incident address or a dropped pin, using the nearest public weather station.
  • Touch-and-go ALOHA parameters: incident name, time, location, chemical and release details. Advanced settings cover ground roughness, source and threat zone.
  • Red, orange and yellow AEGL threat zones with distances you can tap for detail.

Toxic plume modeling for fire departments

Give company officers and incident commanders the same plume picture on their phones, with no desktop software to maintain.

  • Cloud-based and mobile: iPhone, iPad, Android phones and tablets, laptops or desktops.
  • Current traffic flow on the incident map, so you can see which roads run through the impact zone.
  • Share links let police and the Emergency Operations Center view the model without a user ID or app.

Plume and wind field modeling for railroads

Use existing weather sensors to see wind over complex terrain day to day, and model a release before first responders reach a derailment.

  • 3D wind field model over complex terrain from your existing weather sensors.
  • Mobile deployment suited to rail and other quick-response situations.
  • Model a release before first responders arrive at a rail incident.

Fixed-site plume modeling for industrial facilities

Pair LR-x® with fixed weather sensors around your facility so your industrial hazmat team sees how current and forecast weather will carry a release.

  • Fixed systems for refineries, chemical plants and other high-value sites.
  • Connect strategically placed fixed atmospheric sensors, or link a private fixed or mobile sensor as an add-on.
  • Eddy currents around buildings and structures revealed by the 3D wind field.

CBRN plume modeling for military units

LR-x® began as the Army Research Laboratory's L-REAC™ system, built to protect soldiers and civilians from airborne hazards.

  • Developed by the U.S. Army Research Laboratory at White Sands Missile Range, NM.
  • Rapid deployment by units in potential hot zones.
  • Works from as few as one sensor module; more sensors give a more complete picture.

Wildfire smoke and wind field modeling

See how wind moves over mountains and valleys and track dangerous smoke, the job the system did during the 2011 Abrams Fire.

  • Wind vectors mapped over topography from NASA SRTM and USGS elevation data.
  • Tracks dangerous wildfire smoke and helps focus suppression efforts.
  • Tested in a real wildfire by ARL in 2011.
