a Scatter plots show daily precipitation amounts from GSPIC-RT over global land areas, in comparison with baseline precipitation data. The black dashed line represents the ideal consistency line (1:1 line). b Taylor diagrams of daily precipitation estimates for four climatic zones from January 2015 to December 2018, where closer proximity to the observation point (actual precipitation amount) indicates better model performance. c Distribution of global precipitation accumulation in 2018. d Box plots of daily precipitation product evaluation indicators, assessing the model’s performance in correcting near-real-time precipitation data across different precipitation intensities through CC, RMSE, and BIAS key evaluation indicators.
