Mapping was conducted using the REGFLEC model which is an automatic and image-based methodology developed for regional chlorophyll (Cab) and LAI estimation (i.e., Houborg et al., 2007; Houborg and Boegh, 2008; Houborg and Andersen, JARS 3, 2009). REGFLEC combines models for atmospheric correction (6S), canopy reflectance (ACRM) and leaf optics (PROSPECT). The REGFLEC tool corrects for impacts of atmospheric scattering and absorption, soil background reflectance and species specific vegetation characteristics (ie. leaf angle distribution). In this study, the REGFLEC model tool is applied to high spatial (10-20 m) resolution SPOT satellite data for mapping LAI and leaf N of agricultural landscapes located in Denmark, Poland, Scotland, the Netherlands and... |

Leaf biochemistry and biophysical parameters are important for simulating soil‐vegetation‐atmosphere exchanges of energy, water, CO2 and ammonia. The accumulation of leaf nitrogen (N) in vegetation canopies is a major component of the ecosystem N balance, and leaf N concentration and leaf area index (LAI) are important determinants of the maximum CO2 uptake by plants and trees. In NEU, high spatial resolution remote sensing data from the SPOT satellite were acquired to prepare maps of leaf N and LAI for 5 European landscapes. Mapping was conducted using the REGFLEC model which is an automatic and image‐based methodology developed for regional chlorophyll (Cab) and LAI estimation (ie. Houborg and Andersen, JARS 3, 2009). REGFLEC combines models for... |
