Kurzfassung
Leaf Area Index (LAI) and the fraction of absorbed Photosynthetically Active Radiation (fPAR) are frequently used for biophysical modeling of crop growth and yield prediction. This study examines the calculation of LAI and fPAR of cotton using statistical regression with spectral information of RapidEye. Based on the knowledge that commonly used vegetation indices (NDVI, SAVI, EVI) may underperform in the situation of dense vegetation the growing season was divided into main growth and reproductive phases. To account for saturation effects indices including the curvature in the red edge part of the spectra were tested. Field measurements on LAI and fPAR were carried out during the vegetation period of 2011 on cotton fields in Uzbekistan. The LAI/fPAR results for RapidEye data will be used as input for an upscaling to TERRA-MODIS time series and transfer to larger areas of Central Asia.
