Water Vapor and Cloud Formation in the TTL: Simulation Results vs. Satellite Observations [PDF]

, 2012
Driven by analyzed winds and temperature, domain-filling forward trajectory calculations are used to reproduce water vapor and cloud formations in the tropical tropopause layer (TTL).

CALIPSO lidar calibration at 1064 nm: version 4 algorithm [PDF]

Atmospheric Measurement Techniques, 2018
Abstract. Radiometric calibration of space-based elastic backscatter lidars is accomplished by comparing the measured backscatter signals to theoretically expected signals computed for some well-characterized calibration target. For any given system and wavelength, the choice of calibration target is dictated by several considerations, including signal-

Contrail Formation Within Cirrus: Contrail Induced Perturbations and Cirrus Adjustments

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 8, 28 April 2026.
Abstract Contrail formation constitutes a large fraction of the aviation climate impact. But only part of the effect has been studied in detail, as research focused on contrail formation in cloud‐free air. Even though it is known that the impact of contrail formation within cirrus can be detected in space‐born remote sensing data, little research has ...

CALIPSO lidar ratio retrieval over the ocean

Optics Express, 2011
We are demonstrating on a few cases the capability of CALIPSO to retrieve the 532 nm lidar ratio over the ocean when CloudSat surface scattering cross section is used as a constraint. We are presenting the algorithm used and comparisons with the column lidar ratio retrieved by the NASA airborne high spectral resolution lidar.

Lateral Boundary of Cirrus Cloud from CALIPSO Observations [PDF]

Scientific Reports, 2017
AbsractDue to the thinness and small scale of cirrus clouds, its lateral boundary may be missed by conventional passive remote-sensing techniques and climate models. Here, using satellite observations in June–August from 2006 to 2011, a global dataset for the cirrus cloud lateral boundary (CCLB) was established.

Atmospheric Adjustments to In Situ Cirrus Formation in Ice Supersaturated Regions

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 8, 28 April 2026.
Abstract High‐level ice clouds exert a net warming on the climate system because their greenhouse effect outweighs their albedo effect. Focusing on in‐situ cirrus, their formation involves the conversion of upper‐tropospheric water vapor into ice crystals.

Where is the best site on Earth? Domes A, B, C and F, and Ridges A and B [PDF]

, 2009
The Antarctic plateau contains the best sites on earth for many forms of astronomy, but none of the existing bases was selected with astronomy as the primary motivation.

Weak Influence of Surface Pressure on Arctic Radiative States From Winter to Spring Over the Sea‐Ice

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract The Arctic sea‐ice surface energy budget is characterized by two radiative states driven by the presence or absence of opaque clouds that warm the surface. Ground‐based observations from the 1998 SHEBA campaign collected over sea‐ice suggested that the two radiative states correspond to distinct surface pressure values.

Improved Simulation of Seasonal Variation of Arctic Low Clouds by Resolving Subgrid Open Water Fluxes to the Atmosphere in CESM2

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Open water in sea ice significantly influences Arctic low‐cloud formation. However, current global climate models (GCMs), constrained by grid‐scale coupling between the atmosphere and surface components, cannot resolve subgrid heat fluxes and clouds contrasts between open water and sea ice, contributing to biases in Arctic low‐cloud ...
