The Washington Times article “Mapping a picture of Earth’s minute particles from the sky” includes this info:
“For hours each night, a pilot flew a 1968 Aero Commander dual propeller airplane, crisscrossing the skies around the Capital Beltway. But because of what it carried, the plane actually is the only one of its kind in the country.
Inside, there’s a collection, among other technology, of infrared and gamma-ray spectrometers, a neutron detector, scanners, cameras and broadband satellite equipment that remotely transmit chemical and radiological data back to the scientists on the ground.”
EPA ASPECT – On the SceneOn the scene, in the air, when needed, where needed. The EPA ASPECT aircraft continues to provide on-scene commanders with the information they need to make critical decisions.
Algorithms, aircraft, and scientific analysis that allows state of the art detection at a higher sensitivity make the ASPECT program unique. Wheels up on call make the program available when needed. A solid, well developed and practiced concept of operations (CONOPS) makes ASPECT repeatable and reliable.
