AbstractCalibration and validation (CAL/VAL) issues are important to SMOS-like satellite for its scale of swath, pixel resolution and coverage. The project has selected Taklahmgan desert as SMOS calibration site which provide a unique opportunity for the community to look at accuracy, stability and sensitivity of the spaceborne instrument measurements. It also takes part in global action on improvement of SMOS products. Currently, the big hurdle is radio frequency interferences distributed everywhere which makes geographical information in SMOS data shielded by unreasonable man-made coherent signals. In the framework of Dragon-2, we have helped to coordinate interactions between ESA and Chinese relevant department of government, make people aware of the electromagnetic environment and situation then make progress together. A ground based L band radiometer to measure microwave emission from Taklamkan desert and other landscapes (LETAK) has already been built and tested at the same time frame. Data analysis has also been reported in this paper.
