Chemical Capabilities
•	ASPECT uses the principles of remote passive infrared
detection via a Fourier Transform Infrared Spectrometer
(FTS) to detect and quantify gaseous constituents present in
the air column between the aircraft and the ground
•	Chemical detection software is designed to filter out
common atmospheric constituents as it automatically
searches for 78 chemical compounds in near real-time (5 in
the air column below the aircraft
•	Hundreds of other chemicals can be processed by the team
post survey
Deployment History
•	Over 170 responses and deployments since 2001
•	National Special Security Events (NSSE) and Special Event Assessment
Rating (SEAR) level events (e.g., DNC, RNC, Inauguration, Super Bowl)
8 Natural Disasters (e.g., Hurricanes Katrina, Rita, Gustav, and Sandy)
•	Environmental Emergencies (e.g., Deepwater Horizon/BP Oil, West
Fertilizer, Gold King Mine, site characterizations for Superfund sites)
