In-situ and laboratory spectroscopy of vegetation

In-situ and laboratory spectroscopy provide point-based measurements of reflectance of selected samples using portable or laboratory spectroradiometers. This theme is devoted to spectral properties of vegetation, their relation to selected biochemical parameters such as leaf pigments and water content, and their changes due to stress caused, e.g., by drought or pollution. Methods of vegetation spectral properties measurement using spectroradiometers and airborne hyperspectral sensors are explained. The theme is divided into three theoretical lessons, concluded with a quiz and a list of literature:

• Optical parameters of foliage – leaf level
• Principles of laboratory spectroscopy
• Relating imaging spectroscopy and in-situ or laboratory measurements of vegetation properties

A practical exercise is devoted to the comparison of spectra measured by an integrating sphere and a contact probe. An additional tutorial points to the issue of relating spectra obtained from imaging and in-situ spectroscopy.
