Height-dependent thermal properties of extreme-ultraviolet campfires in the quiet Sun

Astronomy & Astrophysics
Context. Small-scale impulsive energy-release events are widely considered a key ingredient of quiet-Sun coronal heating. The discovery of extreme ultraviolet (EUV) campfires by Solar Orbiter has opened a new observational window at unprecedented spatial

An hourly solar radiation prediction model using eXtreme gradient boosting algorithm with the effect of fog-haze

Energy and Built Environment
Hourly global solar radiation data is an important factor for solar energy utilization. Due to the lack of solar radiation observation stations in many areas, some hourly solar radiation models are proposed to predict hourly solar radiation. However, the

Simulation and Reproduction of Direct Solar Radiation Utilizing Grating Anomalous Dispersion

Sensors
The technical challenge of balancing radiant illuminance and the angular diameter of the simulated sun remains unsolved, preventing the realization of a solar simulator with both a 32′ angular diameter and a solar constant irradiance. This paper proposes

Solar Radiation: An Anomalous Decrease of Direct Solar Radiation

Science, 1965
Beginning in November 1963, measurements made at the South Pole of solar radiation at normal incidence indicate a decrease of from 5 to 78 percent of the normal intensity. Similar measurements made at Mauna Loa, Hawaii, show a similar though smaller reduction.
