Attributing Upper‐Tropospheric Warm Biases in CMIP6 Models to Ice Cloud‐Radiation Interaction Deficiencies Over Tropical Oceans

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract We assess the impact of hydrometeor radiative effects on tropical and subtropical Pacific air temperature anomalies (TAA) using Coupled Model Intercomparison Project Phase 6 (CMIP6) model simulations and satellite data. CMIP6 models are grouped by their treatment of frozen hydrometeors: SON2 (explicit cloud and falling ice), SON1 (simplified),

Data assimilation of CALIPSO aerosol observations [PDF]

Atmospheric Chemistry and Physics, 2009
Abstract. We have developed an advanced data assimilation system for a global aerosol model with a four-dimensional ensemble Kalman filter in which the Level 1B data from the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations (CALIPSO) were successfully assimilated for the first time, to the best of the authors' knowledge.

Land‐Ocean Contrast in Low‐Cloud Adiabatic Fraction Modulated by Cloud Thickness and Droplet Size

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Cloud adiabatic fraction (fad) is crucial for understanding cloud microphysics and entrainment mixing. This study presents the first global satellite‐based assessment of land‐ocean contrasts in fad for low‐level clouds. Results show that land clouds have a lower fad (0.22) than oceanic clouds (0.35), consistent across all seasons.

Detection of dust aerosol by combining CALIPSO active lidar and passive IIR measurements [PDF]

Atmospheric Chemistry and Physics, 2010
The version 2 Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations (CALIPSO) dust layer detection method, which is based only on lidar measurements, misclassified about 43% dust layers (mainly dense dust layers) as cloud layers over the ...

Dust Decline Amplifies High‐Cloud Ice‐to‐Liquid Transition and Buffers the Radiative Feedback Under Warming

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract The response of the cloud phase to global warming is a critical yet poorly constrained component of Earth's climate sensitivity. While rising temperatures drive a thermodynamic transition from ice to liquid clouds, the role of ice‐nucleating particles in modulating this shift remains underexplored.

Towards Improved Cirrus Cloud Optical Depths from CALIPSO [PDF]

EPJ Web of Conferences, 2016
This paper reviews recent advances regarding the retrieval of optical depths of semi-transparent cirrus clouds using synergetic analyses of perfectly collocated observations from the CALIOP lidar and the IIR infrared radiometer aboard the CALIPSO satellite.

Self‐Lofting Drives Tropospheric and Stratospheric Transport of Australian Wildfire Smoke to Antarctic Ice

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract The 2019–2020 Australian New Year (ANY) wildfires injected vast amounts of aerosols and trace gases into the atmosphere. Previous studies focused on pyrocumulonimbus (pyroCb) activities that inject smoke directly into the upper troposphere. Our study shows that extensive aerosol plumes emitted into the lower troposphere during ANY wildfires ...

CALIPSOS code report. [PWR]

, 1980
CALIPSOS is a steady-state three-dimensional flow distribution code which predicts the fluid dynamics and heat transfer interactions of the secondary two-phase flow in a steam generator. The mathematical formulation is sufficiently general to accommodate two fluid models described by separate gas and liquid momentum equations.

Calipso e a intransigência do gênero [PDF]

Revista Estudos Feministas, 2018
Resumo: O presente texto propõe-se a investigar a operação dialética que Calipso elabora (Canto 5 da Odisseia - Regresso) ao ser obrigada pelos Deuses (Zeus), contra a sua vontade, a deixar Odisseu seguir o seu regresso à Ítaca. A análise é feita à luz dos estudos de gênero e feministas.

Anomalous Opaque Clouds Revealed by Collocated MODIS and CALIOP Retrievals

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract This paper examines discrepancies between cloud optical thickness (COT) retrievals from the Moderate Resolution Imaging Spectroradiometer (MODIS) cloud product, and cloud opacity measurements from the Cloud‐Aerosol Lidar with Orthogonal Polarization (CALIOP) lidar.
