Infrared photosynthesis
WebbThe value range of an NDVI is -1 to 1 where healthy vegetation generally falls between values of 0.20 to 0.80. Simple Ratio Index (SR): The SR is also well known and often used. It is described as the ratio of light that is scattered in the NIR range to that which is absorbed in the red range. Webbnewly discovered pigments and organisms that extend oxygenic photosynthesis deeper into the near infrared spectral region. Readers will also benefit from the inclusion of a fulsome appendix that incorporates a detailed introduction to the physical basis of photosynthesis, including thermodynamics, kinetics, and spectroscopy.

Plants can't use infrared light for photosynthesis, so they reflect it.
Webb21 juni 2024 · Scientists at Imperial College London have uncovered a previously unknown type of photosynthesis that uses light from the infrared spectrum instead of red light. … Webb25 apr. 2024 · We test the relationship between canopy photosynthesis and reflected near-infrared radiation from vegetation across a range of functional (photosynthetic pathway and capacity) and structural conditions (leaf area index, fraction of green and dead leaves, canopy height, reproductive stage, and leaf angle inclination), weather …
WebbAn action spectrum is a graph of the rate of biological effectiveness plotted against wavelength of light. [1] It is related to absorption spectrum in many systems. Mathematically, it describes the inverse quantity of … Webb15 juni 2024 · A New Kind of Photosynthesis Has Been Discovered, Pushing The Limits on Life. Nature 15 June 2024. By Mike McRae. …
