Spectroscopy can be used to detect individual absorption features due to specific chemical bonds in a solid, liquid, or gas. Every material is formed by chemical bonds, and may be potentially detected by spectroscopy. The detection depends on the spectral coverage, spectral resolution, and signal-to-noise  ratio of the spectrometer, the abundance of the material and the strength of absorption features for that material in the wavelength region measured. In remote sensing configuration, the surface materials mapped must be exposed in the optical surface and the diagnostic absorption features are those in the regions of the spectrum that are reasonably transparent to the atmosphere. Spectroscopy can be used in laboratories on hand samples, in the field with portable field spectrometers, from aircraft, and  from satellites.

Laboratory and field spectrometers play an important role to  the  validation of  remote sensed data and the measurements of parameters necessary to improve the retrieval models.

Spettroscopy  Laboratory

Researchers at INGV- Remote Sensing Group Spectroscopy  are studying and applying different methods for the instrument calibration and data validation devoted to the analysis of laboratory, field, airborne and spacecraft spectrometers. The laboratory supports studies of the electronics and thermal infrared features of the soil.

We welcome opportunities to collaborate with researchers of other research institutes.
