GLM's ability to monitor convection on a global scale via lightning will provide new insight into the formation, distribution, morphology and evolution of storms, and allows investigation into the mechanisms at the core of the global water and energy cycle.

"Along with our teammates from the University of Alabama in Huntsville (UAH), we are enormously excited to be moving forward into the Geostationary Lightning Mapper formulation phase" said Earl Aamodt, Lockheed Martin GLM program manager at the ATC. "Our team has worked together since 1992 on successful lightning imaging missions, and this extensive spaceflight heritage is directly applicable to GLM. The combination of this team's experience and knowledge of GLM requirements, a proven systems engineering approach, and our detailed formulation phase plan will make this formulation phase a success."

The observation of lightning by GLM will provide a ubiquitous means of penetrating cloud tops and detecting convective activity continuously over whole continents and adjacent oceans. This lightning characteristic of clouds is inadequately measured, both temporally and spatially, by current observing systems.

With improved insight into the dynamics and life cycles of storms and weather systems, GLM will also greatly improve understanding of the fast time-scale elements of atmospheric convection. This will lead to a better understanding of the Earth as a system, which combined with long term GLM observations, will lead to significant improvements in monitoring changes in storm climatology. In addition, since intense and increasing in-cloud flashes are known to precede severe weather by tens of minutes, the real-time transmission and distribution of GLM data would greatly improve the lead-time for severe storm warnings, particularly tornadoes.

The Geostationary Operational Environmental Satellite (GOES) mission is a critical part of the U.S. satellite constellation for environmental observations, along with the Polar Operational Environmental Satellite (POES) and Defense Meteorological Satellite Program (DMSP) polar orbiting satellites � both built by Lockheed Martin. GOES is the environmental satellite most familiar to the American public, as its images and time-lapse sequences are the primary visual material of television weather forecasts.

The GOES system � operational since 1975 ?� plays a critical role in weather and environmental forecasting. In orbit high above the equator, GOES satellites are uniquely positioned to observe the development of hazardous weather, such as hurricanes and severe thunderstorms, and to track their movement and intensity so that major losses of life and property can be reduced or avoided.

NOAA manages the GOES program and establishes the requirements, provides funding and distributes environmental data for the United States. NASA will manage the GLM instrument acquisition as a part of its support to NOAA's development of the GOES-R series of satellites.

The ATC is the research and development organization of Lockheed Martin Space Systems Company (LMSSC). LMSSC, a major operating unit of Lockheed Martin Corporation, designs, develops, tests, manufactures and operates a variety of advanced technology systems for military, civil and commercial customers. Chief products include a full-range of space launch systems, including heavy-lift capability, ground systems, remote sensing and communications satellites for commercial and government customers, advanced space observatories and interplanetary spacecraft, fleet ballistic missiles and missile defense systems.
