Dehydration potential of ultrathin clouds at the tropical tropopause. [PDF]

, 2003
We report on the first simultaneous in situ and remote measurements of subvisible cirrus in the uppermost tropical troposphere. The observed cirrus, called UTTCs (ultrathin tropical tropopause clouds), are the geometrically (200–300 m) and optically (τ ≈

Ultrathin Tropical Tropopause Clouds (UTTCs) : I. Cloud morphology and occurrence [PDF]

, 2003
Subvisible cirrus clouds (SVCs) may contribute to dehydration close to the tropical tropopause. The higher and colder SVCs and the larger their ice crystals, the more likely they represent the last efficient point of contact of the gas phase with the ice

Lidar Observed Optical Properties of Tropical Cirrus Clouds Over Gadanki Region

Frontiers in Earth Science, 2020
The presence of cirrus cloud has its impact on the earth’s radiation budget. In order to study the effect of cirrus clouds in the tropical regions, it is essential to understand, and characterize their optical properties.

Cirrus and water vapor in the tropical tropopause layer observed by Upper Atmosphere Research Satellite (UARS) [PDF]

, 2003
The Microwave Limb Sounder (MLS) on Upper Atmosphere Research Satellite (UARS) is sensitive to water vapor and ozone in the lower stratosphere. The Cryogenic Limb Array Etalon Spectrometer (CLAES), another of the instruments on UARS, has a spatial and ...

Determining stages of cirrus evolution: a cloud classification scheme [PDF]

Atmospheric Measurement Techniques, 2017
Cirrus clouds impose high uncertainties on climate prediction, as knowledge on important processes is still incomplete. For instance it remains unclear how cloud microphysical and radiative properties change as the cirrus evolves. Recent studies classify

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

Atmospheric 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

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 ...
