Near-space vehicle in monitoring Qinghai-Tibetan Plateau environmental changes

摘要

Remote sounding of the atmosphere by global positioning system (GPS) radio occultation utilising a GPS satellite and a receiver aboard a low Earth orbiting (LEO) satellite has been proved successful in providing accurate profiles of atmospheric refractivity and water vapor. This technology has generated great interest in atmospheric and climate research communities. The technology is more suitable to monitor the environmental changes in the Qinghai-Tibetan Plateau than space borne GPS occultation. Unlike space borne and airborne GPS occultation, near-space vehicle lies inside the atmosphere, hence the conventional inversion algorithm cannot be applied and new algorithm must be developed. The potential for inversion scheme is exploited.
