Evaluating forecasts of the evolution of the cloudy boundary layer using diurnal composites of radar and lidar observations [PDF]

, 2009
Observations of boundary-layer cloud have been made using radar and lidar at Chilbolton, Hampshire, UK. These have been compared with output from 7 different global and regional models.

Absorption feedback in stratocumulus clouds Influence on cloud top albedo

Tellus A: Dynamic Meteorology and Oceanography, 1994
This paper proposes a feedback mechanism which modifies the enhancement of cloud top albedo expected from an increased concentration of cloud condensation nuclei (CCN). The mechanism is based on the thermodynamic tendency of the cloud to stabilize itself against changes in the absorption of solar radiation.

Assessment of the performance of the Chilbolton 3-GHz Advanced Meteorological radar for cloud-top height retrieval [PDF]

, 2005
The Chilbolton 3-GHz Advanced Meteorological Radar (CAMRa), which is mounted on a fully steerable 25 metre dish, can provide three-dimensional information on the presence of hydrometeors.

Characterization of HRRR-simulated rotor layer wind speeds and clouds along the coast of California [PDF]

Wind Energy Science
Stratocumulus clouds, with their low cloud base and top, affect the atmospheric boundary layer wind and turbulence profile, thereby modulating wind energy resources.

Numerical simulation of clouds and precipitation depending on different relationships between aerosol and cloud droplet spectral dispersion [PDF]

, 2013
The aerosol effects on clouds and precipitation in deep convective cloud systems are investigated using the Weather Research and Forecast (WRF) model with the Morrison two-moment bulk microphysics scheme.

Climate impacts of geoengineering marine stratocumulus clouds [PDF]

Journal of Geophysical Research: Atmospheres, 2009
Theoretical potential geoengineering solutions to the global warming problem have recently been proposed. Here, we present an idealized study of the climate response to deliberately seeding large‐scale stratocumulus cloud decks in the North Pacific, South Pacific, and South Atlantic, thereby inducing cooling via aerosol indirect effects.

Measurement and modeling of diffuse ultraviolet radiation: A review

Photochemistry and Photobiology, EarlyView.
Solar UV radiation consists of direct and diffuse UV components. The diffuse component contributes to the exposure received by humans and to the risk of skin cancer and sun‐related eye disorders. This review aims to determine future research directions for the measurement and modeling of diffuse solar UV radiation.

Retrievals of thick cloud optical depth from the Geoscience Laser Altimeter System (GLAS) by calibration of solar background signal [PDF]

, 2008
Laser beams emitted from the Geoscience Laser Altimeter System (GLAS), as well as other spaceborne laser instruments, can only penetrate clouds to a limit of a few optical depths.

Joint retrievals of cloud and drizzle in marine boundary layer clouds using ground-based radar, lidar and zenith radiances [PDF]

Atmospheric Measurement Techniques, 2015
Active remote sensing of marine boundary-layer clouds is challenging as drizzle drops often dominate the observed radar reflectivity. We present a new method to simultaneously retrieve cloud and drizzle vertical profiles in drizzling boundary-layer ...

Defining Scales of Field Studies and Experiments to Assess Marine Cloud Brightening

AGU Advances, Volume 7, Issue 2, April 2026.
Abstract Solar radiation modification (SRM) is being discussed as a potential option for addressing climate risks while atmospheric greenhouse gas concentrations are reduced to lower levels. However, understanding of the potential efficacy, impacts, benefits and harms of different SRM approaches remains limited.
