Abstract: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 Niño(EP-El Niño) by fast Fourier transform and wavelet transform. The results show that the super EP-El Nio 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.
