The same moment from three rain sources, side by side, with what every rain gauge measured (blue dots; grey = dry). Pick any period: the maps replay it step by step, and the result and the scoreboard below are counted over the whole period.
GK2A satellite from KMA (2 km)–
JMA satellite, Himawari-9 (2 km): heavy-rain areas–
Result: the best source and the average, always on the same hours
All three sources, on the hours all three cover

Scoreboard: which source sees the rain the gauges measure
Day by day, each day on the hours every source of that day covers (tap a day to replay it on the maps above)
What each source has stored (coverage, not a score)
