CMORPH Precipitation Data available

The Climate Prediction Center (CPC) Morphing (CMORPH) technique produces global estimates of hourly precipitation and those data are available in real time at this website. (Other JPSS/ABI-related flood products are available there as well). CMORPH uses microwave data from Polar Orbiters to estimate rainfall. Infrared information is related to those microwave data estimates, and those infrared data (from ABI, AHI, etc) are used to estimate precipitation during times when microwave observations are not present. This morphing technique is thus different from other morphing techniques for Total Precipitable Water (TPW) such as MIMIC that use model data to move quasi-conserved moisture fields to observational data voids. (Training on MIMIC TPW fields).
Hourly and Daily precipitation totals are available at the website. The animation above shows annual precipitation over the course of 6 days. Daily precipitation on 27 August, for example (link), shows the heavy rain accompanying land-falling Hurricane Laura. In the animation, the rains with that system move north to the mid-Mississippi River before being shunted eastward.
Hourly Precipitation, shown below from 12-15 UTC on 3 September 2020, allows for enhanced situational awareness with respect to heavy (or light) rains.
