Field campaign for quantitative remote sensing in Beijing

In order to evaluate and improve the remotely sensed land surface parameters' accuracy and assimilate accumulating remote sensing data with land surface models, an integrate field campaign was carried out during the winter wheat growth season in 2001. The field campaign was funded by the Chinese Special Funds for Major State Basic Research Project: Quantitative remote sensing theory and application of land surface parameters (QRSLSP). Research on scale effect and angular characteristics of remote sensing data is the most important objectivity. Three different scales of research area are responding to different spatial resolution of remote sensing sensors. The experimental database include space-borne remote sensing data, airborne remote sensing data and field observation data. Some significant research advances have been achieved based the experiment data set, while most research proposals are carrying on.
