The research p rogresses ofmetadata and metadata standard at home and meteorological departments were analyzed, and the main p roblems in meteorological data managing and sharing system at p resentwere discussed, and some p rospects ofmetadata requirementwere put forward.

Homogeneity of the climate data is p recondition on studying climate change. This paper used SNTH technique to test the homogeneity of climate series of Lanzhou meteorlogical station, and the inhomogeneity test on meteorological factors such as p recip itation, average temperature, maximum temperature, minimum temperature, average wind speed and sunshine hourswas conducted; meanwhile, the reason was analyzed based on the station history files and metadata information. The results show that inhomogeneity existed in time series of p recip itation, average temperature, maximum temperature, minimum temperature and sunshine hours, and the main reasons were relocation of station, changes of instruments, changes in statistic methods and urban heat island effect.

The new generation operation technology system reformation of the meteorological department put forward the overall goal that the operation technology system of the multi-orbit, the intensive, the research, open style should be established. The construction of the research operation is one of the important goals. This paper briefly reviewed the thought foundation and the policy vein on the construction of the research operation, and analyzed the basic connotation of the research operation by using the analogy induction method, and discussed the primary mission of constructing the regional research operation also
