Shortwave broadband direct normal irradiance
Measurement Categories: Radiometric
Description: The rate at which radiant energy in broad bands of wavelengths shorter than approximately 4{mu}m, that comes directly from the Sun without being scattered or absorbed in the atmosphere, passes through a unit area perpendicular to the direction from the Su
