On the distribution of relative humidity in cirrus clouds [PDF]
Atmospheric Chemistry and Physics, 2004 Abstract. We have analysed relative humidity statistics from measurements in cirrus clouds taken unintentionally during the Measurement of OZone by Airbus In-service airCraft project (MOZAIC). The shapes of the in-cloud humidity distributions change from nearly symmetric in relatively warm cirrus (warmer than −40°) to considerably positively skew (i.e.

Search for Man-Made Cirrus Contrails over Southeast Asia
Terrestrial, Atmospheric and Oceanic Sciences, 2007 In this study we examine the effect of natural perturbations on cirrus cloud cover in the tropics and we look for possible signal of cirrus contrails in tropical air traffic regions focussing on Southeast Asia, a region that has received much less ...

In Situ Measurements of Cirrus Clouds on a Global Scale [PDF]
Atmosphere, 2020 Observations of high-altitude cirrus clouds are reported from measurements made during the routine monitoring of cloud properties on commercial aircraft as part of the In-Service Aircraft for a Global Observing System. The increasing global scale of the measurements is revealed, with 7 years of in situ data producing a unique and rapidly growing ...
