Luminous efficacies of global and diffuse horizontal irradiances in a tropical region
Renewable Energy, 2013Abstract This paper reports results of a study on characteristics of luminous efficacies of tropical global and diffuse horizontal solar irradiances using observed data from a daylight measurement station located in the southern area of Bangkok, Thailand (latitude 13.58°N and longitude 100.44°E).

Parametrization of instantaneous global horizontal irradiance: clear‐sky component
Quarterly Journal of the Royal Meteorological Society, 2013AbstractBased on an accurate atmospheric radiative transfer scheme, a parametrization of instantaneous global horizontal irradiance (GHI) at the Earth's surface has been developed. The scheme is named SUNFLUX and this article describes the development of the scheme for clear‐sky conditions.

Forecasting of Global Horizontal Irradiance Using Sky Cover Indices
ASME 2011 5th International Conference on Energy Sustainability, Parts A, B, and C, 2011This work discusses the relevance of three Sky Cover (SC) indices for solar radiation modeling and forecasting. The three indices are global in the sense that they integrate relevant information from the whole sky and thus encode cloud cover information.

Estimation the DNI from global and diffuse horizontal irradiance for Algeria
3rd International Symposium on Environmental Friendly Energies and Applications (EFEA), 2014Determination of hourly direct normal solar irradiance (DNI) received during an average day of each month is essential for calculating the solar concentrator performance throughout the day. DNI data provided by different databases, spatial or ground-based measurements. While the spatial databases are a useful tool in renewable energy applications, they

Estimation and Applications of Clear Sky Global Horizontal Irradiance at the Equator
Journal of Solar Energy Engineering, 2014We analyze Singapore global horizontal irradiance (GHI) measurements and propose a clear sky GHI model for equatorial regions. The empirical formulation simplifies the atmosphere radiative transfer to a single exponential term. The results are benchmarked using locally collected data. Two applications of the clear sky model are briefly discussed.

Parameterization of instantaneous global horizontal irradiance: Cloudy‐sky component
Journal of Geophysical Research: Atmospheres, 2012Radiation calculations in global numerical weather prediction (NWP) and climate models are usually conducted in 3‐hourly time interval in order to reduce the computational cost. This treatment can lead to an incorrect solar radiation at the Earth's surface which could be one of the error sources in modeled convection and precipitation.
