Remotely sensed satellite data can provide spatial and temporal coverage for global environmental monitoring. Calibration and validation are very important for more accurate satellite products and can contribute to the detection of climate changes on earth. Calibration and validation of satellite products normally use both ground-based and satellite-based data, which have geospatial metainformation and various data policies. Our proposal adopts both the Open Geospatial Consortium (OGC) standards and the virtual organization (VO) concept to develop a calibration and validation system for satellite products. In this research, we construct the Field Observation Network (FON) VO, which provides an interoperable system for various ground-based and satellite-based data by using the OGC standards Sensor Observation Service (SOS). FON VO also makes it possible to protect data policies. Ground-based and satellite-based atmospheric and ground physical parameters are the focus of this study.
