Estimating forest variables, such as photosynthetic light use efficiency, from satellite reflectance data requires understanding the
contribution of photosynthetic vegetation (PV) and nonphotosynthet...
RADIATIVE TRANSFER MODEL INVERSION BASED ON MULTI-TEMPORAL CHRIS/PROBA DATA FOR LAI ESTIMATION
Leaf area index Radiative transfer Dynamic canopy model
font style='font-size:12px;'>
2015/9/8
Leaf area index (LAI) is a key variable for the understanding and modelling of several eco-physiological processes within a
vegetation canopy. The LAI could thus provide vital information for the man...
