摘要
以可长期连续提供全球视角大气水汽分布的MODIS传感器数据为研究对象,以汾渭盆地为实验区,研究了利用MODIS数据建立区域对流层湿延迟模型的理论和方法,得到了该地区的对流层湿延迟模型。通过实际数据验证了该模型可基本反映与地形相关的湿延迟。
MODIS data is taken as the research object, which can provide a global continuous atmospheric vapor distribution. We introduced the principle of the vapor inversion from MODIS data, and also studied the theory and method to establish regional tropospheric zenith wet delay model. We obtained the regional tropospheric zenith wet delay model of the Fenwei basin. It is verified that the model can reflect the terrain-related wet delay, which provided a reference for the establishment of the regional tropospheric wet delay model in other regions, or doing it from other data.
