Abstract

The US Environmental Protection Agency is currently operating an airborne hyperspectral remote infrared spectrometer for the purpose of providing near real-time chemical data to first responders and other response agencies. This system has been designed to fulfill Agency data collection requirements for both traditional chemical emergency response and counter - terrorism activities. The platform consists of a high speed long-wave and mid-wave spectrometer and a multi-spectral infrared line scanner integrated into a mid-sized twin-engine aircraft. Through the use of onboard data processing and short haul data links, chemical information can be relayed to the end user in about ten minutes. An important component of this system is the development of the spectral reference library used to query the incoming data stream. A balance must be reached in providing a library set that is robust enough to provide useful information for the majority of accidents without the overhead of voluminous amounts of rarely used spectral library data. The end goal of the program is to generate a library set which permits a reasonable number of compounds to be automativally processed as data is streamed through the system. This paper will describe the selection technique used to develop the critical list of compounds contained in the library. This paper will likewise describe how this library is integrated into the overall system and the type of data processing and products that are produced.
