Numerical simulations of homogeneously nucleated natural cirrus and contrail-cirrus. Part 1: How different are they?

open access: yesMeteorologische Zeitschrift, 2017
The evolution of contrail-cirrus and natural cirrus formed by homogeneous nucleation is studied over up to ten hours by means of a Large-Eddy Simulation (LES) model equipped with a Lagrangian ice microphysics module.

Measurement errors in cirrus cloud microphysical properties [PDF]

open access: yesAnnales Geophysicae, 1998
The limited accuracy of current cloud microphysics sensors used in cirrus cloud studies imposes limitations on the use of the data to examine the cloud's broadband radiative behaviour, an important element of the global energy balance.

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.

Long-term trend analysis and climatology of tropical cirrus clouds using 16 years of lidar data set over Southern India [PDF]

open access: yesAtmospheric Chemistry and Physics, 2015
Sixteen-year (1998–2013) climatology of cirrus clouds and their macrophysical (base height, top height and geometrical thickness) and optical properties (cloud optical thickness) observed using a ground-based lidar over Gadanki (13.5° N, 79.2° E), India,

Optical and geometrical properties of cirrus clouds in Amazonia derived from 1 year of ground-based lidar measurements [PDF]

open access: yesAtmospheric Chemistry and Physics, 2017
Cirrus clouds cover a large fraction of tropical latitudes and play an important role in Earth's radiation budget. Their optical properties, altitude, vertical and horizontal coverage control their radiative forcing, and hence detailed cirrus ...

An automated cirrus classification [PDF]

open access: yesAtmospheric Chemistry and Physics, 2018
Cirrus clouds play an important role in determining the radiation budget of the earth, but many of their properties remain uncertain, particularly their response to aerosol variations and to warming.

Characteristics and Seasonal Variations of Cirrus Clouds from Polarization Lidar Observations at a 30°N Plain Site

open access: yesRemote Sensing, 2020
Geometrical and optical characteristics of cirrus clouds were studied based on one year of polarization lidar measurements (3969 h on 228 different days between March 2019 and February 2020) at Wuhan (30.5°N, 114.4°E), China.

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.

The Role of Global Thunderstorm Activity in Modulating Global Cirrus Clouds

open access: yesGeophysical Research Letters, 2023
Cirrus clouds provide a significant radiative forcing on the Earth's climate system. This paper looks at the connection in space and time between monthly mean lightning activity observed from the Lightning Imaging Sensor on board the International Space ...

Aerosol–cloud–radiation interaction during Saharan dust episodes: the dusty cirrus puzzle [PDF]

open access: yesAtmospheric Chemistry and Physics, 2023
Dusty cirrus clouds are extended optically thick cirrocumulus decks that occur during strong mineral dust events. So far they have mostly been documented over Europe associated with dust-infused baroclinic storms.
