GPM Has Best Calibrated Microwave Imager in the World

Released on February 7, 2017

This is an infographic describing how the GPM Microwave Imager works and maintains its high degree of calibration, as well as how it contributes to the precipitation rates produced by the mission.

With so many important applications, how does GPM create these maps and make sure they’re accurate? In a recent evaluation, GPM’s microwave imager was named the best calibrated microwave imager to date. So what exactly makes it the best? It’s a combination of better hardware and more advanced technology.
