Solar radiation research encompasses the quantitative characterization, modeling, and variability analysis of electromagnetic energy emitted by the Sun and received at or near Earth, spanning ultraviolet to near‑infrared and sometimes extending to longer wavelengths. This research area investigates solar spectral and broadband irradiance, its spatial and temporal variability driven by solar activity and Earth–Sun geometry, and its modification by atmospheric constituents, clouds, and surface properties. It underpins radiative transfer modeling, climate and weather prediction, solar energy resource assessment, remote sensing retrievals, and studies of radiative forcing, enabling improved parameterizations in climate models and optimized design and siting of solar energy systems.
The Extreme Ultraviolet and X-ray Irradiance Sensors (EXIS) onboard NOAA's GOES-19 satellite, which launched on June 25, 2024, are powered on, performing well, and observing the sun.
