CEOS WGCV mission
The CEOS Working Group on Calibration & Validation (WGCV) Mission is to ensure long-term confidence in the accuracy and quality of satellite-based Earth Observation data and products and provide a forum for the exchange of information about calibration and validation and associated coordination, and cooperative activities.
Objectives:
Sensor-specific calibration and validation
Bio-geophysical validation
Means:
Exchange of data, technical information and documentation
Possible coordination opportunities for space and ground segments rel. obj.
Coordination of Cal/Val activities (campaigns, programs, etc.)
Agreement of common terminology and definitions
