Accurate humidity probe for persistent aviation-contrail conditions Abstract. We present a state-of-the-art humidity probe for in situ airborne water vapor measurements tailored to the humidity range relevant for the formation of persistent aviation contrail cirrus cl...

Our latest paper describes a new humidity probe designed for flight to characterize the very dry air at 10–12 km where jet aircraft can form persistent contrail clouds. These clouds trap heat and contribute to warming the planet.
