Contrails and Induced Cirrus
C loud radiative forcing, the difference between the top-of-atmosphere radiative fluxes for all sky and clear skies, is a straightforward metric to gauge the climate impacts of contrails and contrail cirrus, which constitute a potentially serious long-term environmental issue associated with aviation (Minnis et al. 2004; Wuebbles et al. 2010). The Intergovernmental Panel on Climate Change (IPCC...
متن کاملPersistent Contrails and Contrail Cirrus. Part II: Full Lifetime Behavior
More than 200 large-eddy simulations of long-lived contrails from several-seconds age until their demise have been performed and their lifetime-integrated behavior has been analyzed. The simulations employ sizeresolved microphysics and include variations of effective ice crystal number emission index, temperature, relative humidity with respect to ice, stratification, shear, supersaturated-laye...
متن کاملPotential of airborne lidar measurements for cirrus cloud studies
Aerosol and water vapour measurements were performed with the lidar system WALES of Deutsches Zentrum für Luftund Raumfahrt (DLR) in October and November 2010 during the first mission with the new German research aircraft G55-HALO. Curtains composed of lidar profiles beneath the aircraft show the vertical and horizontal distribution and variability of water vapour mixing ratio and backscatter r...
متن کاملOn the regional climatic impact of contrails: microphysical and radiative properties of contrails and natural cirrus clouds
The impact of contrail-induced cirrus clouds on regional climate is estimated for mean atmospheric conditions of southern Germany in the months of July and October. This is done by use of a regionalized onedimensional radiative convective model (RCM). The in ̄uence of an increased ice cloud cover is studied by comparing RCM results representing climatological values with a modi®ed case. In order...
متن کاملA case study of the radiative forcing of persistent contrails evolving into contrail-induced cirrus
[1] The radiative forcing due to a distinct pattern of persistent contrails that form into contrail-induced cirrus near and over the UK is investigated in detail for a single case study during March 2009. The development of the contrail-induced cirrus is tracked using a number of high-resolution polar orbiting and lower-resolution geostationary satellite instruments and is found to persist for ...
