摘要
利用CMONOC提供的GNSS连续观测数据分析天顶对流层延迟(ZTD)代替水汽的可行性,并利用快速傅里叶变换(FFT)和小波变换(WT)开展GNSS ZTD对超强东部型厄尔尼诺事件的响应分析。结果表明,超强东部型厄尔尼诺事件会增加中国大陆地区水汽含量,在热带及亚热带地区响应更为显著;同时该事件会影响GNSS ZTD的显著变化周期,使9个月的变化周期减弱,0.8~3个月内的变化周期增强。
We analyze the feasibility of GNSS ZTD instead of GNSS PWV using the GNSS continuous observations provided by CMONOC,and analyze the GNSS ZTD response to the super eastern Pacific El Nino(EP-El Nino)by fast Fourier transform and wavelet transform.The results show that the super EP-El Nino event will increase the PWV content in Chinese mainland(the response is more significant in the tropical monsoon zone and subtropical monsoon zone),weaken the 9-month significant period of GNSS ZTD,and increase the significant period within 0.8-3 months.
