The FORMOSAT-7/COSMIC-2 (FS7) had been launched in June 2019. The FS7 has many benefits than FS3 because of the improvements in both hardware and software. Comparison with FS3, FS7 can provide more atmospheric observations and has more data penetration into the boundary layer, especially over the tropical region. In our preliminary result, we have examined the data qualities between FS7 and FS3, and verified FS7 data against other observations, e.g., radiosondes, satellite retrieval products, and products from other RO missions, etc. In the following two years, we will use a global data assimilation system (i.e., GSI system) for the GNSS RO data assimilation and then using the global MPAS model for the prediction. We will investigate the influences of GNSS RO data, including the FS7 RO data, on the predictions of severe weather events, e.g., Typhoon or Mei-Yu front, near Taiwan. The additional observations obtained from TAHOPE/PRECIP-2020 will be assimilated as well and be used for the verification.
