Remote Sensing, 2021 Radiative transfer in the Earth’s atmosphere under clear-sky conditions strongly depends on turbidity due to aerosols and hydrometeors. It is therefore important to know its temporal radiative properties for a given site when the objective is to optimize

Modelling the clear-sky intensity distribution using a sky imager
Solar Energy, 2015 Abstract This paper introduces a new empirical formulation of the clear-sky intensity distribution based on images acquired with a sky imager developed at the PROMES-CNRS laboratory (Perpignan, France). Both the formulation and image processing methodology are detailed and stand for key steps in the development of a high quality cloud detection ...

The influence of the sky radiative temperature on the building energy performance
Magazine of Civil Engineering, 2022 Most of the current sky models correlate with local climatic conditions and specific sites, while not covering different humidity-climatic conditions. In this work, sky emissivity and sky temperature models were reviewed, taking into account the common ...

Uncertainties of parameterized surface downward clear-sky shortwave and all-sky longwave radiation. [PDF]
Atmospheric Chemistry and Physics, 2012 As many environmental models rely on simulating the energy balance at the Earth's surface based on parameterized radiative fluxes, knowledge of the inherent model uncertainties is important.

A Qualitative and Quantitative Evaluation of 8 Clear Sky Models [PDF]
IEEE Transactions on Visualization and Computer Graphics, 2017 We provide a qualitative and quantitative evaluation of 8 clear sky models used in Computer Graphics. We compare the models with each other as well as with measurements and with a reference model from the physics community. After a short summary of the physics of the problem, we present the measurements and the reference model, and how we "invert" it ...

Blue Skies: A Methodology for Data-Driven Clear Sky Modelling [PDF]
Proceedings of the Twenty-Sixth International Joint Conference on Artificial Intelligence, 2017 One of the major challenges confronting the widespread adoption of solar energy is the uncertainty of production. The energy generated by photo-voltaic systems is a function of the received solar irradiance which varies due to atmospheric and weather conditions. A key component required for forecasting irradiance accurately is the clear sky model which
