GBOV (Ground-Based Observation for Validation): A Copernicus Service for Validation of Land Products.

This presentation will focus on GBOV activities, introducing the service, its distribution system, and its growing network as well as its achievements after the first operation phase. Some examples from the GBOV ground stations will be reported to illustrate the instrument setup and datasets and more importantly the lessons learnt from the first phase. GBOV phase 1 has been a success thanks to a large community of scientist providing high quality dataset. GBOV phase 2 is willing to strengthen its relationship with ground network and go further in stimulating interactions with the global community.
