Plain Language Summary: Extreme precipitation is expected to increase in a warmer climate at the same rate of the surface humidity, that is the Clausius-Clapeyron rate (~6%/K in the tropics). This study investigates the scaling of the extreme precipitation over the tropical ocean using an ensemble of satellite-based precipitation products and SST analysis. The microwave constellation-based products show a very robust positive scaling range between 300K to 302.5K, with an ensemble mean very close to the 6%/K theoretical expectation.
