... a new suite of indices have been developed that exploits narrow band spectroradiometric data. The physiological reflectance index (PRI) introduced by Gamon et al. (1992) follows the form of equation 1 and is based on reflectances at 531 nm (band 1) and 570 nm (band 2) wavelengths. Gamon et al. (1997) renamed this the photochemical reflectance index and suggested that the index was a good predictor of photosynthetic radiation use efficiency at the leaf or canopy level, if the canopy is uniform and completely covers the soil background. The index has not shown sensitivity to nutrient stress, but it is affected by water stress with severe wilting ... 3, record 2, English, - photochemical%20reflectance%20index

Heating treatments increase aboveground net primary production (detectable via the Normalized Difference Vegetation Index, a measure of green biomass) and enhance gross photosynthesis (detectable via the Photochemical Reflectance Index, a measure of xanthophyll cycle pigment activity and relative photosynthetic rate). ... Heating enhanced the Photochemical Reflectance Index (PRI) slightly relative to that of controls. This enhancement was most visible near noon, and relaxed by 3:00 pm ..., suggesting that this effect was a temporally dynamic one reflecting altered physiological activity towards midday. 5, record 2, English, - photochemical%20reflectance%20index

Dans le but d’évaluer la possibilité de mesurer les indices de vigueur des forêts à partir de la réflectance spectrale foliaire, [...] Nous avons mesuré la réflectance des pousses des sapins baumiers de chacun des traitements en laboratoire au moyen d’un spectroradiomètre portatif dont la gamme spectrale s’étendait de 350 nm à 2 500 nm. [...] La plupart des gammes d’ondes ont révélé que les traitements avaient eu des effets marqués, et les gammes d’ondes les plus significatives se trouvaient dans la région d’absorption de la chlorophylle entre 500 nm et 740 nm. [...] Les traitements ont influé sur les indices de réflectance, qui sont définis comme le rapport et l’écart normalisé entre la gamme d’ondes la plus significative à 711 nm et la gamme d’ondes la moins significative à 913 nm (P < 0,0001). 3, record 2, French, - indice%20de%20r%C3%A9flectance

Spot radiometer. This instrument measures the average radiance over a specific spectral region. Usually, this radiance is converted to an apparent blackbody surface temperature or, by selecting a surface emissivity, to the apparent surface temperature. To create a thermographic image, the user must map the single data points obtained with the instrument. 1, record 4, English, - spot%20radiometer
