DARPA’s SIGMA+ program conducted a week-long deployment of advanced chemical and biological sensing systems in the Indianapolis metro region in August, collecting more than 250 hours of daily life background atmospheric data across five neighborhoods that helped train algorithms to more accurately detect chemical and biological threats. The testing marked the first time in the program the advanced laboratory grade instruments for chemical and biological sensing were successfully deployed as mobile sensors, increasing their versatility on the SIGMA+ network.

The DARPA SIGMA+ chemical sensors were developed by Physical Sciences Inc., Andover, Massachusetts and by Bruker Detection Corp., Billerica, Massachusetts. The biological sensors were developed by Battelle Memorial Institute, Columbus, Ohio.
