Laboratory spectral reflectance measurements of pine/spruce twigs and snow

The dataset contains laboratory spectral reflectance (350-2500 nm) measurements of natural snow samples and pine and spruce twigs measured with an ASD Field Spec Pro JR spectroradiometer. For snow types sampled, in situ snow measurements are accompanied with the reflectance data. The measurements have been conducted at the premises of the Arctic Space Centre of the Finnish Meteorological Institute, Sodankylä, Finland (N67.361833, E26.634154, WGS84). The data are structured as CSV-files. Snow specific surface area (SSA) information and photographs of the snow samples are available for part of the measured snow types and are organized into separate folders. For this version a data example plot (Data_example_laboratory.png) was added to have a quick visualisation of the sort of the data available.
