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,

Observation of cirrus clouds with GLORIA during the WISE campaign: detection methods and cirrus characterization [PDF]

open access: yesAtmospheric Measurement Techniques, 2021
Cirrus clouds contribute to the general radiation budget of the Earth and play an important role in climate projections. Of special interest are optically thin cirrus clouds close to the tropopause due to the fact that their impact is not yet well ...

Selected topics on the interaction between cirrus clouds and embedded contrails [PDF]

open access: yesAtmospheric Chemistry and Physics, 2012
Persistent contrails and natural cirrus clouds often coexist in the upper troposphere and contrails can be embedded within cirrus clouds. The present paper deals with some questions regarding the interaction of cirrus clouds and embedded contrails.

Characteristics of supersaturation in midlatitude cirrus clouds and their adjacent cloud-free air [PDF]

open access: yesAtmospheric Chemistry and Physics, 2023
Water vapor measurements of midlatitude cirrus clouds, obtained by the WAter vapour Lidar Experiment in Space (WALES) lidar system during the Mid-Latitude Cirrus (ML-CIRRUS) airborne campaign, which took place in the spring of 2014 over central Europe ...

A microphysics guide to cirrus clouds – Part 1: Cirrus types [PDF]

open access: yesAtmospheric Chemistry and Physics, 2016
Abstract. The microphysical and radiative properties of cirrus clouds continue to be beyond understanding and thus still represent one of the largest uncertainties in the prediction of the Earth's climate (IPCC, 2013). Our study aims to provide a guide to cirrus microphysics, which is compiled from an extensive set of model simulations, covering the ...

Search for Man-Made Cirrus Contrails over Southeast Asia

open access: yesTerrestrial, Atmospheric and Oceanic Sciences, 2007
In this study we examine the effect of natural perturbations on cirrus cloud cover in the tropics and we look for possible signal of cirrus contrails in tropical air traffic regions focussing on Southeast Asia, a region that has received much less ...

Extinction Curves, Distances, and Clumpiness of Diffuse Interstellar Dust Clouds [PDF]

open access: yes, 1999
We present CCD photometry in UBVRI of several thousand Galactic field stars in four large (>1 degree^2) regions centered on diffuse interstellar dust clouds, commonly referred to as ``cirrus'' clouds (with optical depth A_V less than unity).

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

open access: yesAtmospheric 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

Lidar Observed Optical Properties of Tropical Cirrus Clouds Over Gadanki Region

open access: yesFrontiers 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.

Revisiting global satellite observations of stratospheric cirrus clouds [PDF]

open access: yesAtmospheric Chemistry and Physics, 2020
As knowledge about the cirrus clouds in the lower stratosphere is limited, reliable long-term measurements are needed to assess their characteristics, radiative impact and important role in upper troposphere and lower stratosphere (UTLS) chemistry.
