Lockheed Martin is currently installing a new system on the WC-130J ‘Hurricane Hunter’ aircraft that should enhance the accuracy of data collected during storm tracking missions.

The system is a Stepped Frequency Microwave Radiometer (SFMR) and can accurately measure wind speed and rainfall at sea-level, enabling more precise forecasting as to the severity and direction of major storms. Currently the surface winds are only estimated using a mathematical formula at the US’s National Hurricane Center.
This technology will enhance the ability to issue more accurate watches and warnings.
