| 摘 要： | 考虑到当前已有的ZTD、ZWD垂直剖面模型时空分辨率低等不足，以NASA提供的2014~2016年气象再分析资料MERRA-2为基础，分析中国区域ZTD、ZWD高程缩放因子的时空分布特性。结果表明，ZTD、ZWD高程缩放因子均具有明显的年周期和半年周期变化，与经度、纬度相关性显著，且两者时空分布特性具有明显差异。

| Abstract: | Taking into account the low temporal-spatial resolution of the existing ZTD and ZWD vertical profile model, we analyze the temporal-spatial distribution characteristics of ZTD and ZWD height scale factors in China based on the 2014-2016 meteorological reanalysis data MERRA-2 provided by NASA. The results show that both ZTD and ZWD height scale factors have obvious annual and semi-annual changes, which are significantly correlated with longitude and latitude, and the temporal-spatial distribution characteristics of ZTD and ZWD height scale factors are significantly different. |
