Near-infrared radiation

From Glossary of Meteorology



near-infrared radiation

The preferred term for the shorter wavelengths in the infrared region of the electromagnetic spectrum extending from about 0.75 μm (visible red) to around 3 μm.

The term usually emphasizes the radiation reflected from plant materials, which peaks around 0.85 μm. Near-infrared is sometimes called solar infrared, since the flux of radiation in these wavelengths is a maximum during the daylight hours.
