"NCU/GPSARC developed a 1DVAR RO data retrieval system, which retrieves the FORMOSAT-7 (FS7) RO refractivity to obtain atmospheric temperaturemoisture profiles. The high vertical resolution atmospheric soundings are comparable with radiosondes. The system is one of the components of the TROPS,it is operationally performed by CWB TACC. Based on Chen et al. (2020), we further apply the nonlocal RO operator with FS7 data in an advanced hybrid data assimilation system for the detection of tropical cyclogenesis. The processing systemdetection platform have been implemented at GPSARC."
