Note: ① H (Hit): the number of times that real precipitation events are correctly observed by satellite products; ② M (Miss): the number of precipitations actually produced on the ground when the satellite did not observe precipitation; ③ F (False): The number of times that the satellite observed precipitation while there was no precipitation on the ground.
