摘要
基于GPS/GLONASS观测资料,利用卡尔曼滤波算法层析河北省CORS站网上空水汽,分析在中雨、阵雨转多云、多云转晴的天气下,水汽层析值的大小及其随时间的变化。分析结果表明地基GNSS水汽层析算法能够探测到短时间内大气湿度的起伏变化。
Based on the GPS/GLONASS observation data,the air water vapor in HBCORS was analyzed by Kalman filter algorithm,and the value of water vapor tomography and its change with time under moderate rain,shower to cloudy,cloudy to sunny weather were analyzed.The results show that the ground-based GNSS water vapor tomography algorithm can detect the fluctuation of atmospheric humidity in a short time.
