The specific objectives of the HYPERNETS project are to:
- Develop a new low-cost multi-head hyperspectral spectroradiometer dedicated to land and water surface reflectance validation
- Develop and integrate around the HYPERNETS instrument a) a low-cost automated azimuth- and zenith-pointing system and, b) a low-cost stable relative calibration device,
- Deploy the HYPERNETS instrument/pointing/calibration system at sites equipped with data acquisition, data storage, transmission, processing and real-time Internet distribution and with (site-dependent) synergy with other instruments (sunphotometers, in-water optical measurements, flux
towers, etc.), - Integrate these new instruments/systems within measurement networks as an upgrade of/or in parallel with existing networks for validation of satellite data over water and land (AERONET-OC,RADCALNET),
- Test and demonstrate instrument performance by deployment at 24 sites, covering a range of water and land types and a range of climatic (cold/temperate/hot, dry/wet) and logistic (accessible/remote, European/non-European) conditions,
- Exploit data from the instruments for the radiometric validation of atmospherically-corrected products from a large number of optical satellite missions including Sentinel 3A and 3B, Sentinel 2A and 2B, MODIS AQUA and TERRA, VIIRS, Landsat-8, PROBA-V, CHRIS-PROBA, ENMAP,
Pléiades, etc., - Provide quality-controlled data of known uncertainty from the validation sites to the international user community (including Copernicus services, space agencies and validation entities) via networks according to user requirements and following internationally agreed standards, protocols and quality control,
- Prepare commercial production of the instrument, including regular maintenance and calibration services, by establishing a business plan and setting up a new spin-off private company, and,
- Ensure dissemination of activities to the international science community (including Copernicus actors, space agencies and validation programs) and to the general public.
