Alan Hills fills liquid nitrogen in the Trace Organic Gas Analyzer (TOGA) instrument onboard the DC-8 aircraft at Building 703 in Palmdale, CA. This instrument measures volatile organic compounds (VOCs) in the atmosphere.
The DC-8 aircraft is prepared for its last mission, ASIA-AQ (Airborne and Satellite Investigation of Asian Air Quality), that will collect detailed air quality data over several locations in Asia to improve the understanding of local air quality in collaboration with local scientists, air quality agencies, and government partners
