Abstract
Mountain-based GPS radio occultation observations were conducted at the Yaogu mountain and Jiugong mountain in Hubei province, respectively. Occultation event data were successfully obtained. Analysis and statistics of the occultation events have been completed. The principle and methods estimating bending angles of the radio rays and atmospheric refractivity profiles with the mountain-based radio occultation data are given. The simulation data of mountain-based occultation events are used for testing the inversion method. Testing results show that the inversion method is efficient. The atmospheric refractivity profiles below the height of the GPS receiver are obtained with this inversion technique, as well as the bending angle of rays. The results suggest that the mountain-based occultation technique is a potential new method for monitoring lower atmospheric environments.
