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.

Formulations of moist thermodynamics for atmospheric modelling

, 2015
Internal energy, enthalpy and entropy are the key quantities to study thermodynamic properties of the moist atmosphere, because they correspond to the First (internal energy and enthalpy) and Second (entropy) Laws of thermodynamics.

Comparison of a global-climate model to a cloud-system resolving model for the long-term response of thin stratocumulus clouds to preindustrial and present-day aerosol conditions [PDF]

Atmospheric Chemistry and Physics, 2010
The response of a case of thin, warm marine-boundary-layer (MBL) clouds to preindustrial (PI) and present-day (PD) conditions is simulated by a cloud-system resolving model (CSRM).

Gravity‐wave‐induced perturbations in marine stratocumulus [PDF]

Quarterly Journal of the Royal Meteorological Society, 2012
AbstractWe discuss the role of atmospheric gravity waves in modulating cloud radiative and dynamical properties over the southeast Pacific. Satellite imagery and satellite‐retrieved cloud properties during October 2008 illustrate three distinct episodes of horizontal propagation of gravity wave trains across the large‐scale stratocumulus (Sc) cloud ...

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.

Robust Yet Diverse Tropical Responses to Antarctic Meltwater Across Models

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Continued melting of Antarctic ice sheets and shelves adds freshwater to the Southern Ocean (SO), enhancing stratification and inducing surface cooling. This cooling influences tropical climate through coupled atmosphere–ocean interactions, though model responses vary.

How do CMIP6 Models Represent the Vertical Structure and Chemical Properties of Biomass‐Burning Aerosols Emitted in Central Africa?

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract CMIP6 climate models have difficulties representing the strong absorption properties of biomass‐burning aerosols (BBA) over the Southeast Atlantic and the associated direct forcing. This study takes advantage of unique in situ and remote sensing observations to evaluate the vertical profile and chemical composition of BBA, which are key ...

Unveiling the Hidden Warming Layer: Metre‐scale Clear‐Sky Radiative Effects at Stratocumulus Cloud Top

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 6, 28 March 2026.
Abstract We identify a previously unresolved layer, which we term as the “W‐Layer”, warming at about 2K hr−1 directly above the stratocumulus cloud top using the line‐by‐line radiative transfer model ARTS. The W‐Layer, being only about 5 m thick, poses observational and simulational challenges.

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.

Coral δ13C Reveals Little Ice Age Dimming of Tropical Surface Shortwave Radiation Not Captured by Climate Models

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Tropical low‐cloud feedback is the largest source of uncertainty in climate sensitivity, yet multi‐century records of surface shortwave radiation are scarce. We calibrate Porites coral δ13C against satellite photosynthetically available radiation (PAR) and reconstruct monthly PAR for the northern South China Sea during the Medieval Climate ...
