Mid-infrared spectra database for arable topsoil samples

This database contains diffuse reflectance spectra in the mid-infrared of arable topsoil samples (DRIFT-MIRS). Three different datasets are involved: (i) 1013 soil samples from Germany, Belgium, the Netherlands and Luxembourg taken from the EU LUCAS survey (2009), (ii) a regional dataset (n=385) from Schleswig Holstein, and (iii) 513 soil samples from four heterogeneous arable fields in Germany. Details and the associated ground truth data can be found in aggregated form in the publication Leenen et al. (2022). The individual data of the LUCAS data are the property of the EU-JRC in Ispra/Italy and can be requested there.
