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),

Pseudo‐Radar Reflectivity by Applying U‐Net Models to Global Passive Microwave Brightness Temperatures

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 9, 16 May 2026.
Abstract Spaceborne radar systems such as the Global Precipitation Measurement Mission (GPM)'s core satellite Dual‐frequency Precipitation Radar (DPR) provide global insight into precipitation structure, storm morphology, and hydrological cycles. However, their limited spatial and temporal sampling and high cost constrain their ability to continuously ...

Uncertainty Assessment of the Vertically-Resolved Cloud Amount for Joint CloudSat–CALIPSO Radar–Lidar Observations

Remote Sensing, 2021
The joint CloudSat–Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) climatology remains the only dataset that provides a global, vertically-resolved cloud amount statistic.

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 ...

A Novel Methodology for Probing the Observed Influence of the QBO on Tropical Tropospheric Climate

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 7, 16 April 2026.
Abstract The stratospheric Quasi‐Biennial Oscillation (QBO) is characterized by descending bands of wind and temperature anomalies in the tropical stratosphere with a mean period of ∼28 months. Numerous studies have argued that the QBO has a significant impact on tropical tropospheric climate.

Comparison of CloudSat and TRMM radar reflectivities

Journal of Earth System Science, 2013
Comparison of reflectivity data of radars onboard CloudSat and TRMM is performed using coincident overpasses. The contoured frequency by altitude diagrams (CFADs) are constructed for two cases: (a) only include collocated vertical profiles that are most likely to be raining and (b) include all collocated profiles along with cloudy pixels falling within

Height‐Dependent Sensitivity of Cloud Scales to Surface Temperature Anomaly Observed by Active Satellites

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract As a key macrophysical property, cloud horizontal scale plays a critical role in cloud radiative effect (CRE), precipitation and convective structures. Until now, however, how cloud scales vary with surface temperature anomaly and their subsequent impacts on CRE and precipitation remains unclear.

Artificial intelligence (AI)-derived 3D cloud tomography from geostationary 2D satellite data [PDF]

Atmospheric Measurement Techniques
Satellite instruments provide high-temporal-resolution data on a global scale, but extracting 3D information from current instruments remains a challenge. Most observational data are two-dimensional (2D), offering either cloud top information or vertical

The Amazon River‐Breeze Circulation Limits Detection of Aerosol‐Cloud Interactions in Warm Clouds

AGU Advances, Volume 7, Issue 2, April 2026.
Abstract Increased aerosol concentrations can brighten low‐level clouds and extend their lifetimes, but aerosol–cloud interactions (ACI) remain highly uncertain and difficult to quantify. We show that part of this uncertainty is caused by topographical influences on clouds, that is, those arising from land–water contrasts.

CloudSat Observes a Labrador Sea Polar Low

Bulletin of the American Meteorological Society, 2015
Abstract Polar lows generate hazardous weather conditions in the Arctic, and satellites have played a key role in understanding their genesis and dynamics. For the first time, an overpass of the CloudSat 94-GHz cloud radar over a polar low has been recorded.
