WINTER Instrument Payload

WINTER is using the NSF/NCAR C-130 research aircraft, essentially a flying laboratory, to conduct research flights in the Northeast Metropolitan Corridor, the Ohio River Valley, and the Southeast regions. The C-130 originally served as a cargo plane, so it is able to carry a large payload of instruments while also having a range of more than 1500 miles and the ability to fly between 1000 – 15,000 feet in altitude. These aspects are important in order to fully characterize the atmospheric chemistry of a region, because pollutants can be far reaching as winds transport them. 

For each field project a specialized suite of instruments are uploaded to the aircraft to meet the research needs of the study. As part of WINTER, the C-130 will carry a suite of state-of-the-art instruments designed to measure a range of reactive trace gases, atmospheric fine particles, and meteorological parameters such as temperature, radiation, and winds.
