Spatial Heterogeneity and Inhomogeneity of Cirrus Microphysical Properties on Kilometer Spatial Scales

open access: yesGeophysical Research Letters
Previous studies reporting the spatial inhomogeneity and heterogeneity of cirrus cloud properties have primarily been case studies derived from relatively small data sets.

A cloud detection neural network for above-aircraft clouds using airborne cameras

open access: yesFrontiers in Remote Sensing, 2023
For aerosol, cloud, land, and ocean remote sensing, the development of accurate cloud detection methods, or cloud masks, is extremely important. For airborne passive remotesensing, it is also important to identify when clouds are above the aircraft since

Contrail formation within cirrus: ICON-LEM simulations of the impact of cirrus cloud properties on contrail formation [PDF]

open access: yesAtmospheric Chemistry and Physics, 2022
Contrail formation within natural cirrus introduces large perturbations in cirrus ice crystal number concentrations, leading to modifications in cirrus microphysical and optical properties.

Tropical Cirrus in Global Storm‐Resolving Models: 2. Cirrus Life Cycle and Top‐of‐Atmosphere Radiative Fluxes

open access: yesEarth and Space Science, 2022
Cirrus clouds of various thicknesses and radiative characteristics extend over much of the tropics, especially around deep convection. They are difficult to observe due to their high altitude and sometimes small optical depths. They are also difficult to

Tropical Cirrus in Global Storm‐Resolving Models: 1. Role of Deep Convection

open access: yesEarth and Space Science, 2022
Pervasive cirrus clouds in the upper troposphere and tropical tropopause layer (TTL) influence the climate by altering the top‐of‐atmosphere radiation balance and stratospheric water vapor budget.

Differences in microphysical properties of cirrus at high and mid-latitudes [PDF]

open access: yesAtmospheric Chemistry and Physics, 2023
Despite their proven importance for the atmospheric radiative energy budget, the effect of cirrus on climate and the magnitude of their modification by human activity is not well quantified. Besides anthropogenic pollution sources on the ground, aviation

Long-Range Transport of Water Channelized through the Southern Subtropical Jet

open access: yesAtmosphere, 2018
In this study, an air mass (containing a cirrus cloud) was detected by light detection and ranging (lidar) above São Paulo (Brazil) in June 2007 and tracked around the globe, thanks to Lagrangian calculations as well as ground-based and satellite ...

In Situ Measurements of Cirrus Clouds on a Global Scale

open access: yesAtmosphere, 2020
Observations of high-altitude cirrus clouds are reported from measurements made during the routine monitoring of cloud properties on commercial aircraft as part of the In-Service Aircraft for a Global Observing System.

Effect of Residual and Transformation Choice on Computational Aspects of Biomechanical Parameter Estimation of Soft Tissues

open access: yesBioengineering, 2019
Several nonlinear and anisotropic constitutive models have been proposed to describe the biomechanical properties of soft tissues, and reliably estimating the unknown parameters in these models using experimental data is an important step towards ...

Contrail Cirrus [PDF]

open access: yes, 2002
A contrail (a term introduced for “condensation trail” in 1942 by British pilots) is a visible cloud forming behind aircraft, mainly due to water vapor emissions from the engines. Contrails were first observed behind propeller-driven aircraft in 1915 but form as well from the exhaust of jet engines in cold ambient air (Schumann 1996a).
