Numerical simulations of contrail-to-cirrus transition – Part 2: Impact of initial ice crystal number, radiation, stratification, secondary nucleation and layer depth
contrail-to-cirrus transition initial ice crystal number secondary nucleation layer depth
2010/2/21
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 stud...
Single ice crystal measurements during nucleation experiments with the depolarization detector IODE
Single ice crystal measurements nucleation experiments depolarization detector IODE
2010/2/1
In order to determine the efficiency of different aerosol particles to nucleate ice, an Ice Optical DEpolarization detector (IODE) was developed to distinguish between water droplets and ice crystals ...
Gas phase acetic acid and its qualitative effects on snow crystal morphology and the quasi-liquid layer
Gas phase acetic acid qualitative effects snow crystal morphology quasi-liquid layer
2009/11/9
A chamber was constructed within which snow crystals were grown on a string at various temperatures, relative humidities, and acetic acid gas phase mole fractions. The temperature, relative humidity, ...
Ice supersaturations and cirrus cloud crystal numbers
Ice supersaturations cirrus cloud crystal numbers
2009/6/16
Upper tropospheric observations outside and inside of cirrus clouds indicate water vapour mixing ratios sometimes exceeding water saturation. Relative humidities over ice (RHice) of up to and more tha...
Hydration of the lower stratosphere by ice crystal geysers over land convective systems
Hydration lower stratosphere ice crystal geysers land convective systems
2009/3/31
The possible impact of deep convective overshooting over land has been explored by six simultaneous soundings of water vapour, particles and ozone in the lower stratosphere next to Mesoscale Convectiv...
Impact of H2SO4/H2O coating and ice crystal size on radiative properties of sub-visible cirrus
H2SO4/H2O coating ice crystal size radiative properties sub-visible cirrus
2009/1/16
Recent laboratory experiments showed that at conditions resembling those near the tropopause region, small ice particles can be coated by a liquid H2SO4/H2O over-layer formed after the freezing of dil...
Single particle analysis of ice crystal residuals observed in orographic wave clouds over Scandinavia during INTACC experiment
Single particle analysis of ice crystal orographic wave clouds Scandinavia INTACC experiment
2009/1/8
Individual ice crystal residual particles collected over Scandinavia during the INTACC (INTeraction of Aerosol and Cold Clouds) experiment in October 1999 were analyzed by Scanning Electron Microscopy...

Small-scale gravity waves ER-2 MMS/MTP wind temperature measurements CRYSTAL-FACE
2009/1/5
Lower stratospheric wind and temperature measurements made from NASA's high-altitude ER-2 research aircraft during the CRYSTAL-FACE campaign in July 2002 were analyzed to retrieve information on small...
Extinction coefficients retrieved in deep tropical ice clouds from lidar observations using a CALIPSO-like algorithm compared to in-situ measurements from the cloud integrating nephelometer during CRYSTAL-FACE
Extinction coefficient tropical ice clouds lidar cloud integrating nephelometer CRYSTAL-FACE
2008/12/3
This paper presents a comparison of lidar ratios and volume extinction coefficients in tropical ice clouds, retrieved using observations from two instruments: the 532-nm Cloud Physics Lidar (CPL), and...
