Variation of spectral composition of photosynthetically active radiation penetrating into the Norway spruce canopy

on the overlying leaf area index but also on the solar elevation and the portion of diffuse to direct solar irradiance above the canopy. Radiation interacts with plant organs of the solar radiation spectrum and de...

Influence of air pollutants on spectral regions from ultraviolet to visible solar radiation

set without division according to solar elevation angle. These models showed no apparent influence of air pollutants on incident solar radiation but did reveal humidity. Secondly, after eliminating the major effec...

Spectral composition of photosynthetically active radiation penetrating into a Norway spruce canopy: the opposite dynamics of the blue/red spectral ratio during clear and overcast days

(characterized by diffuse index DI > 0.7) was almost independent of the solar elevation angle elevation angles during days with prevailing direct radiation (DI < 0.3). The PAR......

Relation between spectral and non-spectral characteristics of radiation incident on the assimilatory apparatus

The radiation environment is traditionally quantified in terms of radiant energy and irradiance of PAR, but detailed characterization of spectral irradiance or photon flux distributions is missing. Information about changes of PAR spectral compositio...
