Satellite observations of seasonality and long-term trends in cirrus cloud properties over Europe: investigation of possible aviation impacts [PDF]

open access: yesAtmospheric Chemistry and Physics, 2022
Linear contrails and contrail cirrus induced by global aviation have long been known to contribute to climate change by warming the atmosphere. Besides increasing global cirrus cloudiness, aviation may also alter the properties of natural cirrus clouds ...

Effect of cloud‐scale vertical velocity on the contribution of homogeneous nucleation to cirrus formation and radiative forcing

open access: yesGeophysical Research Letters, 2016
Ice nucleation is a critical process for the ice crystal formation in cirrus clouds. The relative contribution of homogeneous nucleation versus heterogeneous nucleation to cirrus formation differs between measurements and predictions from general ...

Optical and Geometrical Properties of Cirrus Clouds over the Tibetan Plateau Measured by LiDAR and Radiosonde Sounding during the Summertime in 2014

open access: yesRemote Sensing, 2019
Optical and geometrical characteristics of the cirrus clouds over Naqu (4508 m a.s.l., 31.48° N, 92.06° E), in the Tibetan Plateau were determined from LiDAR and radiosonde measurements performed during the third TIbetan Plateau EXperiment of ...

Study on the Parameters of Ice Clouds Based on 1.5 µm Micropulse Polarization Lidar

open access: yesRemote Sensing, 2022
Dust aerosols can participate in the heterogeneous nucleation process as effective ice nucleation particles, thus changing the physical properties of clouds.

Climatological and radiative properties of midlatitude cirrus clouds derived by automatic evaluation of lidar measurements [PDF]

open access: yesAtmospheric Chemistry and Physics, 2016
Cirrus, i.e., high, thin clouds that are fully glaciated, play an important role in the Earth's radiation budget as they interact with both long- and shortwave radiation and affect the water vapor budget of the upper troposphere and stratosphere. Here,

The role of ASM on the formation and properties of cirrus clouds over the Tibetan Plateau

open access: yesTellus: Series B, Chemical and Physical Meteorology, 2019
Cirrus clouds play a significant role in the Earth’s energy balance and in the hydrological cycle of the atmosphere. Here, a high-performance Micro Pulse Lidar was continuously used to investigate cirrus cloud formation and characteristics at Ali (32.50 ...

Active Imaging through Cirrus Clouds

open access: yesOptics Express, 1997
The presence of clouds of ice particles in the uplink and downlink path of an illumination beam can severely impede the performance of an active imaging system. Depending on the optical depth of the cloud, i.e., its density and depth, the beam can be completely scattered and extinguished, or the beam can pass through the cloud with some fraction ...

Parameterization of single scattering properties of mid-latitude cirrus clouds for fast radiative transfer models using particle mixtures [PDF]

open access: yes, 2008
A new parameterization of single scattering properties has been developed for mid latitude cirrus clouds, to be used in weather prediction and global circulation models. Ice clouds are treated as a mixture of ice crystals of different habits.

Spatial and Temporal Characteristics of Cirrus Clouds over the Tibetan Plateau Based on CALIPSO and AIRS Observations

open access: yesAdvances in Meteorology, 2019
The spatial and temporal distribution characteristics of high clouds over the Tibetan Plateau (TP) were studied using the Atmospheric Infrared Sounder (AIRS) and the GCM-Oriented CALIPSO Cloud Product (CALIPSO-GOCCP) monthly mean cloud products from 2007

Cirrus clouds in a global climate model with a statistical cirrus cloud scheme [PDF]

open access: yesAtmospheric Chemistry and Physics, 2009
Abstract. A statistical cirrus cloud scheme that accounts for mesoscale temperature perturbations is implemented into a coupled aerosol and atmospheric circulation model to better represent both cloud fraction and subgrid-scale supersaturation in global climate models.
