Local Rapid Evaluation of Atmospheric Conditions System

From Wikipedia, the free encyclopedia

The Local Rapid Evaluation of Atmospheric Conditions (L-REAC) System was a computerized weather sensor system designed by the U.S. Army Research Laboratory (ARL) that became operational in 2011.[1]

Purpose

[edit]

The system was designed to warn soldiers and civilians of airborne threats, such as chemical attacks or toxic spills.[2] The purpose of L-REAC was to provide wind monitoring and modeling,[3] which acted as a decision aid for soldiers facing environmental hazards.[2]

History

[edit]

A research meteorologist at ARL developed the first L-REAC prototype.[4] After conducting a survey of commercially available technology from 2003–2007, ARL identified a need for a local atmospheric assessment system. Three studies conducted at White Sands Missile Range, New Mexico, in the early 2000s revealed a requirement for emergency first responders to have up-to-date atmospheric information on local conditions.[1]

During the mid 2000s, it was also reported that U.S. Army soldiers stationed in Iraq were experiencing toxic fumes while working near burn pits.[5] The L-REAC concept was produced from 2009-2011 at White Sands Missile Range as part of a study investigating the airflow around an urban building and small building clusters.[2]

In June 2017, ARL licensed the technology to Diamond B Technology Solutions in Billings, Montana.[4][6] Rebranded as LR-x, the system assisted in tracking environmental emergencies, such as wildfire smoke during fire suppression efforts.[7]

Operation

[edit]

The L-REAC provided 3D weather models that generated wind field and plume outputs, displaying near real-time meteorological data on a map background.[2]  The models included terrain and buildings, and displayed danger zones and weather conditions (i.e. wind speed, wind direction, temperature, and relative humidity).[7]
