An integrated model of soil-canopy spectral radiances, photosynthesis, fluorescence, temperature and energy balance [PDF]

, 2009
This paper presents the model SCOPE (Soil Canopy Observation, Photochemistry and Energy fluxes), which is a vertical (1-D) integrated radiative transfer and energy balance model. The model links visible to thermal infrared radiance spectra (0.4 to 50 μm)

Evaluation of the Condition of Respiration and Photosynthesis by Measuring Chlorophyll Fluorescence in Cyanobacteria

Bio-Protocol, 2018
Chlorophyll fluorescence measurements have been widely used to monitor the condition of photosynthesis. Furthermore, chlorophyll fluorescence from cyanobacteria reflects the condition of respiration, since cyanobacterial photosynthesis shares several ...

CHLOROPHYLL a FLUORESCENCE ANALYSIS IN FORESTS

Annali di Botanica, 2016
A European-wide assessment of chlorophyll a fluorescence (ChlF, prompt fluorescence on dark-adapted samples) parameters in forest ecosystems was carried out in the years 2012-2013, within the 7FP FunDivEUROPE project. A total of 1596 trees growing in 209 stands distributed in six countries, from Mediterranean to boreal sites, were sampled.
