The Interactive Visualization of Vegetation Reflectance Models (IVVRM) tool is an interactive reflectance modeling environment focusing on the PROSPECT + SAIL (PROSAIL) radiative transfer model (RTM) family. Moreover, the forest reflectance canopy INFORM model has been included. All code is written in Python allowing a time-efficient computation and a progressive visualization of the results for all settings, sensor options, or model members. In the following tutorial, we will retrieve vegetation biophysical and biochemical variables from a measured field spectrum using the IVVRM tool. The tutorial will improve understanding of how vegetation interacts with radiation and specifically how the different vegetation variables influence reflectance and absorbance in different spectral regions of the optical domain. Further, it will demonstrate the diversity of vegetation reflectance signatures and the contained information. Moreover, the effect of equifinality and its implications for variable retrieval can be investigated. Students are advised to go through the lecture “Retrieval approaches of vegetation traits from imaging spectroscopy data” before starting with this tutorial.
