  1. Energy in the visible and near-visible portion of the electromagnetic spectrum (0.4–1.0 μm in wavelength).

  2. In meteorology, a term used loosely to distinguish radiation in the visible and near-visible portions of the electromagnetic spectrum (roughly 0.4–4.0 μm in wavelength), usually of solar origin, from that at longer wavelengths (longwave radiation), usually of terrestrial origin.
