Copernicus CAL/VAL Solution (CCVS). 01/12/2020 - 30/11/2022

Abstract

The objective of the Copernicus Cal/Val Solution (CCVS) is to define a holistic solution for all Copernicus Sentinel missions (either operational or planned) to overcome current limitations of Calibration and Validation (Cal/Val) activities. Operational Cal/Val is required to ensure the quality of and build confidence in Copernicus data. However, these activities are currently limited by the following considerations: • The requirements and objectives need to be revisited to consider new usage of Copernicus products, inter-operability requirements, and to anticipate the needs of future Copernicus missions • Current Cal/Val activities are constrained by programmatic and budgetary requirements and do not necessarily follow scientific priorities • Cal/Val activities depend on the operational availability of high-quality Fiducial Reference Measurements (FRM) which are today mostly provided by external entities without strong commitment to the Copernicus program • Synergies within Copernicus and with other national and international programs are not systematically explored. To address these limitations CCVS will propose: • An updated specification of Cal/Val requirements for the Sentinel missions, taking into account inter-operability needs • An overview of existing Calibration and Validation sources and means • A gap analysis identifying missing elements and required developments in terms of technologies and instrumentation, Cal/Val methods, instrumented sites and dissemination service. • A comprehensive Copernicus Cal/Val Solution to organize the long-term provision of FRM for Sentinel missions • A roadmap documenting how the Cal/Val Solution can be implemented, highlighting responsibility, cost and schedule aspects. This plan will be elaborated in concertation with all stakeholders through four Working Groups gathering European Space Agencies, Copernicus Services, measurements and International partners.

Readiness of ICOS for necessities of integrated global observations (RINGO). 01/01/2017 - 31/01/2019

Abstract

Readiness of ICOS for Necessities of integrated Global Observations (RINGO) is a H2020 EU project that serves to further developed and support the ICOS research infrastructure. Within this project the University of Antwerp has a task that aims to investigate the ability to apply terrestrial light Detection and Ranging (LiDAR) measurements to estimate above ground biomass at forest ecosystems. Aboveground biomass is crucial component of the carbon balance of forest ecosystems however it is very difficult to accurately estimate. LiDAR is a new and promising technique that offers the possibility to obtain highly accurate estimates of tree volumes. Within this project we will select several test sites in Belgium with different tree species which will be scanned and at each site several trees will be destructively harvested to validate estimated volume. In a second stage several ICOS sites in Belgium and neighbouring countries will be visited to perform LiDAR scans in order to estimate Aboveground biomass accurately. The outcome of this project will be a protocol to perform LiDAR measurements at the ICOS ecosystem station.
