摘要

With the ever increasing precision of space techniques, the study of the errors in atmospheric refractive delay has become one of the ways of improving the observational accuracy. In order to reduce the influence of selection of atmospheric profile on the mapping function of atmospheric refractive delay, the adopted atmospheric profile has gradually changed from the past standard atmospheric model to radiosonde atmospheric profiles. Using the data of two representative radiosonde stations, the mapping functions provided by standard atmospheric model is compared with the results of radiosonde observations. The reliability of the mapping function given by standard atmosphere is investigated, and the selection of geophysical parameters is briefly discussed.
