Cloud enhancement of global horizontal irradiance in California and Hawaii [PDF]

Solar Energy, 2016
Abstract Clouds significantly attenuate ground-level solar irradiance causing substantial reduction in photovoltaic power output capacity. However, partly cloudy skies may lead to temporary enhancement of local Global Horizontal Irradiance (GHI) above the clear-sky ceiling and, at times, the extraterrestrial irradiance. Such enhancements are referred

Performance Assessment of Global Horizontal Irradiance Models in All-Sky Conditions

Energies, 2021
Solar irradiance models contribute to mitigating the lack of measurement data at a ground station. Conventionally, the models relied on physical calculations or empirical correlations.

Analyzing Regional and Local Changes in Irradiance during the 2019 Total Solar Eclipse in Chile, Using Field Observations and Analytical Modeling

Energies, 2021
Solar eclipses are astronomic phenomena in which the Earth’s moon transits between the planet and the Sun, projecting a shadow onto the planet’s surface.

On the Relationship Between Ground- and Satellite-Based Global Horizontal Irradiance

IGARSS 2022 - 2022 IEEE International Geoscience and Remote Sensing Symposium, 2022
Global horizontal irradiance (GHI) plays a significant role in maintaining the earth's ecological balance and generating electricity in photovoltaic systems. While the satellites have more range, they have been shown to over/under-estimate the true values of GHI that are observed at the ground-based stations.
