AtmosphereThis study aims to achieve the classification of the cirrus clouds over the Observatory of Haute-Provence (OHP) in France. Rayleigh–Mie–Raman lidar measurements, in conjunction with the ERA5 dataset, are analyzed to provide geometrical morphology and ...

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 7, 16 April 2026.Abstract In this study, we examine the impact of variations in gravity wave properties on the ice crystal number concentrations in the tropical tropopause layer (TTL). Analysis of quasi‐Lagrangian superpressure balloon measurements from the Stratéole‐2 campaign shows that high‐frequency waves dominate the occurrence of relatively large vertical wind ...

Effects of cirrus near the tropopause on anvil cirrus dynamics
Geophysical Research Letters, 2006 Recent space and airborne observations have noted tenuous cirrus near the tropopause and above deep convective anvil outflow. We use a cloud‐resolving model, initialized with aircraft observations taken during the CRYSTAL‐FACE experiment, to explore the effects of such cirrus layers on anvil evolution.

Remote sounding through semi-transparent cirrus cloud [PDF]
A large portion of the earth is covered by thin semi-transparent cirrus cloud. The cirrus results from the natural injection of moisture into the upper troposphere by deep convection (i.e., anvils) and from man-made moisture injected into the upper ...

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 7, 16 April 2026.Abstract The accuracy of height‐resolved dust microphysical retrieval from LiDARs has been greatly improved by the recently developed BOREAL (Basic algOrithm for REtrieval of Aerosol with LiDAR) algorithm which describes non‐spherical dust particles with the Irregular‐Hexahedral (IH) model and inverts 3β (backscattering at 355, 532, and 1,064 nm) + 2α (

Theory and observations of ice particle evolution in cirrus using Doppler radar: evidence for aggregation [PDF]
, 2006 Vertically pointing Doppler radar has been used to study the evolution of ice particles as they sediment through a cirrus cloud. The measured Doppler fall speeds, together with radar-derived estimates for the altitude of cloud top, are used to estimate a

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract Narrow bipolar events (NBEs) are often generated in overshooting thunderclouds (OT) penetrating the stratosphere. However, how and under what conditions OT produces such discharges remains unclear. With 3‐year lightning observations and simultaneous cloud top brightness temperature measurements over South China, we developed a more accurate OT

ETO cloud studies for FIRE 2, part 1 [PDF]
This research program in support of Project FIRE (First ISCCP Regional Experiment) involved two efforts. The results of the first effort, which were in direct support of the Extended Time Observations (ETO) component, are described here.

Geophysical 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 ...
