Surface Solar Extremes in the Most Irradiated Region on Earth, Altiplano
Bulletin of the American Meteorological Society, 2023 Abstract Satellites have consistently pointed to the Altiplano of the Atacama Desert as the place on Earth where the world’s highest surface irradiance occurs. This region, near the Tropic of Capricorn, is characterized by its high elevation, prevalent cloudless conditions, and relatively low concentrations of ozone, aerosols, and precipitable water ...

Mechanisms of surface solar irradiance variability under broken clouds [PDF]
Atmospheric Chemistry and PhysicsSurface solar irradiance variability is present under all broken clouds, but the patterns, magnitude of variability, and driving mechanisms vary greatly with cloud type.

On the Connection between Solar Surface Magnetic Flux and the Total Solar Irradiance
The Astrophysical Journal, 2021 Abstract Solar surface magnetic flux evolution plays a dominant role in the variability of total solar irradiance (TSI). Different proxies of magnetic activity have been introduced to correlate solar variability and TSI. We present the daily strong flux densities (SFDs) and weak flux densities (WFDs) defined with three magnetic ...

UV Irradiance Enhancements by Scattering of Solar Radiation from Clouds
Atmosphere, 2015 Scattering of solar radiation by clouds can reduce or enhance solar global irradiance compared to cloudless-sky irradiance at the Earth’s surface. Cloud effects to global irradiance can be described by Cloud Modification Factors (CMF).

Reconstruction of solar irradiance variations in cycle 23: Is solar surface magnetism the cause? [PDF]
Astronomy & Astrophysics, 2003 A model of solar irradiance variations is presented which is based on the assumption that solar surface magnetism is responsible for all total irradiance changes on time scales of days to years. A time series of daily magnetograms and empirical models of the thermal structure of magnetic features (sunspots, faculae) are combined to reconstruct total ...

Sensitivity of the RMI's MAGIC/Heliosat-2 method to relevant input data [PDF]
Advances in Science and Research, 2013 Appropriate information on solar resources is very important for a variety of technological areas. Based on the potential of retrieving global horizontal irradiance from satellite data, an enhanced version of the Heliosat-2 method has been implemented at
