SPECCHIO is a spectral information system designed to hold reference spectra and spectral campaign data obtained by spectroradiometers. MetEOC-3 is going to use a dedicated SPECCHIO spectral information system instance to deal with the multifaceted spectral point data accumulated in various activities related to sensor CAL/VAL.

MetEOC-3 is going to use a dedicated SPECCHIO spectral information system instance to deal with the multifaceted spectral point data accumulated in various activities related to sensor CAL/VAL. SPECCHIO is a specialised software solution to allow the organised storage of spectral data accompanied with detailed metadata to describe the sampling conditions, experimental setups and target properties. One key feature is the easy sharing of data within a research team and the selection of spectral data through metadata queries.

Within MetEOC-3 the SPECCHIO system will be used to handle data stemming from spectral field data collections at the Gobabeb RadCalNet site. This will include ground reflectance factors obtained with ASD field spectroradiometers, and bidirectional reflectance distribution functions (BRDF) approximated from goniometric measurements taken by the GRASS system. Furthermore it will store BRDF data of sand samples stemming from pseudo-invariant calibration sites (PICS), such as sites in the Libyan desert.

SPECCHIO can also be set up to automatically ingest data from the optical sensors at the Gobabeb node, making data available in near-real time to the research team (Figure 1).
