Aircraft contrails develop into contrail cirrus by depositional growth and sedimentation of ice
particles and horizontal spreading due to wind shear. Factors controlling this development …

Citizen science projects encourage the general public to participate in scientific research.
Participants can contribute large volumes of data over broad spatial and temporal frames; …

Photogrammetric methods and analysis results for contrails observed with wide-angle
cameras are described. Four cameras of two different types (view angle< 90° or whole-sky …

Regular visual observations of persistent contrails over Reading, UK, have been used to
evaluate radiosonde measurements of temperature and humidity defining cold ice …

The cirrus-level “condensation trails”(contrails) produced by jet aircraft are considered to
influence surface climate and its recent changes. To reveal the synoptic atmospheric …

Although geographers are highly visible in research into contemporary climate changes
accompanying greenhouse gas increases (“global warming”), a relatively little explored …

On 21 September 2012 the entire sky was covered by contrails over the Gulf of Lyon (NW of
the Mediterranean basin). These clouds were well recorded by ground observers as well as …

Aircraft induced contrails have been found to have a net warming influence on the climate
system, with strong regional dependence. Persistent linear contrails are detectable in 1 Km …

The impact of air traffic on climate is dominated by the contribution of aircraft induced cirrus.
Hence, any mitigation strategy has to consider the production of contrails and cirrus clouds …

The cirrus-level 'condensation trails'(contrails) produced by jet aircraft often occur as sub-
regional-scale 'outbreaks' of multiple contrails, suggested as contributing to post~ 1965 …
