WGCV

The mission of the CEOS Working Group on Calibration & Validation (WGCV) is to ensure long-term confidence in the accuracy and quality of Earth Observation data and products and to provide a forum for the exchange of information about calibration and validation, including the coordination of cooperative activities. 

Calibration is the process of quantitatively defining a system’s response to known and controlled signal inputs. Validation, on the other hand, is the process of assessing, by independent means, the quality of the data products derived from those system outputs.

Our Working Group addresses the need for standardizing the ways that different data sources are combined to ensure interoperability among existing and future Earth Observing systems.  The WGCV promotes the international exchange of technical information and documentation, joint experiments, and the sharing of facilities, expertise, and resources. This makes the WGCV the focal point for all things related to calibration and validation in the international user community. The WGCV Subgroups also conduct many activities around specific topics and sensor types.

For more information about the overall mission and objectives of the WGCV, we invite you to please have a look at the WGCV Terms of Reference.  Information about current and upcoming WGCV activities are outlined within the overall CEOS 3-Year Work Plan (for the period 2016-2018). We also produce a detailed 5-Year Work Plan pertaining specifically to WGCV activities, which will be updated soon.
