WebSoil FTIR-ATR spectra were integrated with remote sensing data to offer a framework for SOM mapping. This framework included optimization of calibration size, prediction of SOM content for sampled sites based on the fusion of FTIR-ATR spectra, Sentinel-2 bands, indices, and DEM derivates, and generation of a SOM map by machine learning. WebAug 20, 2024 · This is a multiple reflection accessory which works by using the Si wafer as the ATR crystal, coupling the light into and out of the wafer using two 45° prisms. It provides 33 reflections from the coated surface for a 0.770 mm-thick silicon wafer and 51 reflections of the coated surface of a 0.50 mm-thick Si wafer.
