Visualization depicting Post-Tropical Cyclone Hermine as observed by the Global Precipitation Measurement (GPM) Core Satellite on September 6th, 2016. GPM/GMI precipitation rates are displayed as the camera moves in on the storm.

On September 6 at 2:06 p.m. EDT (1806 UTC), NASA's Global Precipitation Measurement mission or GPM core observatory satellite flew above Post-Tropical Cyclone Hermine. At that time, Hermine still had maximum sustained winds of about 58 mph (50 knots).

The GPM Core Observatory carries two instruments that show the location and intensity of rain and snow, which defines a crucial part of the storm structure – and how it will behave. The GPM Microwave Imager sees through the tops of clouds to observe how much and where precipitation occurs, and the Dual-frequency Precipitation Radar observes precise details of precipitation in 3-dimensions.

GPM data is part of the toolbox of satellite data used by forecasters and scientists to understand how storms behave. GPM is a joint mission between NASA and the Japan Aerospace Exploration Agency. Current and future data sets are available with free registration to users from NASA Goddard's Precipitation Processing Center website.

Color bar for liquid precipitation rates (ie, rain rates). Shades of green represent low amounts of liquid precipitation, whereas shades of red represent high amounts of precipitation.
