At NASA's Goddard Space Flight Center in Greenbelt, Maryland, an analysis of the tropical cyclone's rainfall was derived from data collected by GPM's Microwave Imager (GMI) and GPM's Dual-Frequency Precipitation Radar (DPR) instruments. GPM clearly showed the extreme rainfall in Kenanga's well-defined circular eyewall. The heaviest rainfall was found by GPM in the tropical cyclone's southeastern quadrant. GPM's radar (DPR Ku Band) measured precipitation there falling at a rate of over 161 mm (6.3 inches) per hour on that side of the tropical cyclone.

A 3-D view of the storm was created at Goddard that showed the estimated relative heights of storms within tropical cyclone Kenanga. Those heights are based on measurements by the GPM satellite's radar (DPR Ku Band) blended with estimates from Japan's HIMAWARI-8 satellite's infrared temperatures. GPM's radar probes of Kenanga's eastern side indicated that storm tops in that part of the tropical cyclone were reaching heights above 12.2 km (7.6 miles). GPM is a joint mission between NASA and the Japan Aerospace Exploration Agency, JAXA.
