Accurate Tornado Warnings

Bethesda-based Lockheed Martin is conducting final tests on a new addition to its long-deployed GOES weather satellite.

The Geostationary Lightning Mapper (GLM) will record all cloud-to-cloud and cloud-to-ground lightning activity over the entire Americas.

In other words, the whole enchilada: every single lightning strike will be detected by this near-infrared device.

That in-cloud lightning activity is critical to giving as much as thirty minutes' warning of a tornado spawning. The complete scan will reveal an individual storm's "jump signature," a sudden acceleration of cloud-to-cloud lightning activity. This will also reduce false alarms.

Lockheed has scheduled final thermal and thermal vacuum testing for the coming months.

The Goddard Flight Center right here in Maryland helps manage development of GOES instruments.

Deployment of this advanced storm detection can't come a minute too soon, as unusual tornado activity continues to wreak havoc across the nation's southern and midwestern regions.
