WebMay 29, 2024 · Table 4 Summary statistics of ZTD differences: GNSS − GNSS/WRF-ICS combination. Full size table. Generally, all combination variants exploiting GNSS data showed better performances in terms of standard deviations compared to the background model. A positive impact of the GNSS is clearly visible in all variants while the best one … WebThe current study examines the impact of assimilating GNSS-ZTD data on the performance of the WRF model in terms of simulating PWV and rainfall. The topic may be of interest, but it has been quite extensively addressed in previous studies, even in Italy (Lagasio et al., 2024; Mascitelli et al., 2024, 2024), which is the
