“…Zhao, Yao, Yao, and Zhang (2018) used the layered products from the ECMWF ERA‐Interim reanalysis data to calculate ZHD and T m in China for GNSS PWV retrieval. The pressure layer profile for GNSS PWV retrieval has been widely used to analyze or monitor extreme weather events, such as rainstorm, typhoon, ENSO, and drought (W. Jiang et al., 2017; Suparta & Rahman, 2016; Zhao, Liu, Yao, et al., 2020; Zhao, Ma, Yao, & Yao, 2019; Zhao, Ma, Yao, Liu, et al., 2019). Meanwhile, extensive studies have been conducted on the development of global T m empirical models to meet the requirements for real‐time GNSS PWV estimation (Huang et al., 2018; Sun et al., 2019a; Yao et al., 2014), which have largely accelerated the development of GNSS meteorology.…”
