INFLUENCE OF SKY CONDITIONS ON ESTIMATION OF PHOTOSYNTHETIC PHOTON FLUX DENSITY FOR AGRICULTURAL ECOSYSTEM
PPFD PAR Solar radiation PAR fraction Quantum-to-energy ratio Diffuse ratio Clearness index Sky conditions
2018/5/16
Photosynthetic photon flux density (PPFD: μmol m−2 s−1) is indispensable for plant physiology processes in photosynthesis. However, PPFD is seldom measured, so that PPFD ...
Adaptive k-tree sample plot for the estimation of stem density: An empirical approach
plotless sampling distance sampling bias efficiency forest sampling
2018/3/6
Available budgets for the inventory of non-commercial woodlands are small. Therefore, there has been increased
interest in using distance methods, such as k-tree sampling, which are faster than fixed...
