Abstract:
Using an RHtestV2 software package, this paper tested the inhomogeneities of monthly air pressure series in Three Gorges areas and then the discontinuities were adjusted. The results show that for most stations, the inhomogeneities or change points can be detected and are almost consistent with the station relocation time in metadata. At the same time, the air pressure series were adjusted. This adjusted dataset is more reliable in climate change research or local climate impact analysis after Three Gorges sluice. At Zigui Station, there were 7year parallel observations and we also use the difference method to adjust the air pressure series. The results show that the two methods both gave reasonably adjusted air pressure series.
