Solar irradiation measurements, such as global horizontal irradiance (GHI), diffuse horizontal irradiance (DHI) and direct normal irradiance (DNI) are covered, and these parameters help to comply ...

NASA’s Parker Solar Probe has flown closer to the Sun than ever before, offering the first direct glimpse into the turbulent ...

The researchers used decomposition models of solar radiation, which are commonly applied to estimate diffuse horizontal irradiance (DHI) from measured GHI, to predict accurately diffuse PAR in ...
