Cloud Cover Diurnal Cycles in Satellite Data and Regional Climate Model Simulations
The amount and diurnal cycle of cloud cover play an important role in the energy and water cycle of the earth-atmosphere system and influence the radiation budget of the earth. Due to its importance and the challenging nature of its quantification, cloud

A Cloud‐Free Approach to Modeling Daily Downwelling Longwave Irradiance at Global Scale
Parametric modeling of downwelling longwave irradiance under all‐sky conditions (LW↓) typically involves “correcting” a clear‐ (or non‐overcast) sky model estimate using solar‐irradiance‐based proxies of cloud cover in lieu of actual cloud cover given ...

Photolysis rates in correlated overlapping cloud fields: Cloud-J 7.3c [PDF]
A new approach for modeling photolysis rates (J values) in atmospheres with fractional cloud cover has been developed and is implemented as Cloud-J – a multi-scattering eight-stream radiative transfer model for solar radiation based on Fast-J.

Model estimation for solar generation forecasting using cloud cover data [PDF]
This paper presents a parametric model approach to address the problem of photovoltaic generation forecasting in a scenario where measurements of meteorological variables, i.e., solar irradiance and temperature, are not available at the plant site. This scenario is relevant to electricity network operation, when a large number of PV plants are deployed

Important non-local effects of deforestation on cloud cover changes in CMIP6 models
Recent satellite and in-situ measurements show that forests can influence regional and global cloud cover through biophysical processes. However, forest’s possible local and non-local impacts on clouds remain unclear.

Modelling Cloud Cover Climatology over Tropical Climates in Ghana
Clouds play a crucial role in Earth’s climate system by modulating radiation fluxes via reflection and scattering, and thus the slightest variation in their spatial coverage significantly alters the climate response. Until now, due to the sparse distribution of advanced observation stations, large uncertainties in cloud climatology remain for many ...
