Intercomparison of radiative forcing calculations of stratospheric water vapour and contrails

open access: yesMeteorologische Zeitschrift, 2009
Seven groups have participated in an intercomparison study of calculations of radiative forcing (RF) due to stratospheric water vapour (SWV) and contrails.

Long-lived contrails and convective cirrus above the tropical tropopause

open access: yes, 2016
. This study has two objectives: (1) it characterizes contrails at very low temperatures and (2) it discusses convective cirrus in which the contrails occurred.

Numerical simulations of contrail-to-cirrus transition – Part 2: Impact of initial ice crystal number, radiation, stratification, secondary nucleation and layer depth [PDF]

open access: yes, 2010
Simulations of contrail-to-cirrus transition were performed with an LES model. In Part 1 the impact of relative humidity, temperature and vertical wind shear was explored in a detailed parametric study.

Statistical Contrail Forecasting

open access: yesJournal of Applied Meteorology, 2001
Abstract The current operational Air Force Weather Agency condensation trail (contrail) forecast technique is based on the Appleman algorithm, developed in the 1950s, with minor modifications. The Appleman algorithm requires accurate measurements or forecasts of ambient flight-level temperature, relative humidity, and pressure, as well as the amount of

Is there a trend in cirrus cloud cover due to aircraft traffic? [PDF]

open access: yes, 2005
Trends in cirrus cloud cover have been estimated based on 16 years of data from ISCCP (International Satellite Cloud Climatology Project). The results have been spatially correlated with aircraft density data to determine the changes in cirrus cloud ...

Contrails, contrail cirrus, and ship tracks

open access: yes, 2006
The following text is an enlarged version of the conference tutorial lecture on contrails, contrail cirrus, and ship tracks. I start with a general introduction into aerosol effects on clouds. Contrail formation and persistence, aviation’s share to cirrus trends and ship tracks are treated then.

Eduard, Sasha, and I Go to the Black Sea

open access: yes, 2014
During the coffee break I tell Eduard that one of the bigwigs from his lab creeps me out. To him this is no surprise. He asks if I have gone swimming in the Black Sea. No. Not yet. I plan to go this afternoon, when most of the conference participants are
