The dependence of the surface solar irradiance on cloud and aerosol

AIP Conference Proceedings, 2009
To quantify radiative forcing of aerosol and to investigate the dependence of the horizontal UV, visible and NIR on total optical depth (TOD) and cloudiness, narrowband surface solar irradiances were measured and analyzed for direct and diffuse component.

Fuzzy modeling of solar irradiance on inclined surfaces

Solar Energy, 2003
A model of solar irradiance on arbitrarily oriented inclined surfaces is proposed, based on fuzzy logic procedures. The behavior of the proposed model is similar to that of other models of increased performance such as the models of Perez or Gueymard, though it requires only a very limited number of classes and adjustable parameters.

Estimation of the hourly solar irradiance on a horizontal surface

Solar Energy, 1986
Abstract Experimental measurements for the hourly solar irradiance on a horizontal surface are carried out in Makkah and Jeddah, Saudi Arabia. A semiempirical formula to predict the hourly global solar irradiance is obtained using standard least squares fitting technique.

Measurements of solar ultraviolet irradiance on inclined surfaces

Journal of Optics A: Pure and Applied Optics, 2004
We present pyranometer and biometer results of total solar UV irradiance (295?385?nm) and erythemal irradiance measured on inclined surfaces in Rosario, Argentina (32?57' S, 60?38' W, 25?m a.s.l.), on clear-sky days near the southern hemisphere summer and winter solstices and spring equinox.

Methods for estimating solar irradiation on a horizontal surface

International Journal of Ambient Energy, 1988
SYNOPSIS Incidence of solar radiation on an arbitrary surface is required for a variety of applications such as agricultural meteorology, photobiology, animal husbandry, daylighting, comfort air conditioning, building architecture and solar energy utilization.

How much of the solar irradiance variations is caused by the magnetic field at the solar surface?

Advances in Space Research, 2002
Abstract The contribution to total solar irradiance variations by the magnetic field at the solar surface is estimated. Detailed models of the irradiance changes on the basis of magnetograms show that magnetic features at the solar surface account for over 90% of the irradiance variations on a solar rotation time scale and at least 70% on a solar ...

Worldwide solar radiation benchmark of modelled surface irradiance

2022
<p>Modelled irradiance data based on satellite products is frequently used in solar energy applications and atmospheric sciences. This kind of data is offered by many different institutional or commercial providers, and currently it is not possible for users to independently identify the best provider for their specific application and ...

Improvement in Surface Solar Irradiance Estimation Using HRV/MSG Data [PDF]

Remote Sensing, 2018
The Advanced Model for the Estimation of Surface Solar Irradiance (AMESIS) was developed at the Institute of Methodologies for Environmental Analysis of the National Research Council of Italy (IMAA-CNR) to derive surface solar irradiance from SEVIRI radiometer on board the MSG geostationary satellite.

Surface solar irradiance maps from seviri MSG data

2010 IEEE International Geoscience and Remote Sensing Symposium, 2010
A scheme for solar irradiance retrieval for the Europe from Meteosat Second Generation (MSG) data is here proposed. The surface irradiance is obtained by interpolation of multidimensional LUT which is generated using the radiative transfer code libRadtran.

A Generative Approach for Surface Solar Irradiance Nowcasting

Accurate short-term forecasting of surface solar irradiance (SSI) is essential for renewable energy integration and trading considerations. In operations, it enables flexibility mechanisms, provides a hedge against rapid weather transitions and overall facilitates decision-making for intraday arbitrage.
