Timothy Lang (ST11) is a coauthor on an article titled, “Employing Optical Lightning Data to identify lightning flashes associated to Terrestrial Gamma-ray Flashes,” which was recently accepted for publication in the Bulletin of Atmospheric Science and Technology. Rich Blakeslee, formerly of the NASA MSFC Emeritus program, is also a coauthor on the study. The study – which was led by Christoph Köhn of the Technical University of Denmark (DTU) – used data from the International Space Station Lightning Imaging Sensor (ISS LIS) and the Atmosphere-Space Interactions Monitor (ASIM; also on the ISS) to improve our understanding of what types of lightning flashes are associated with terrestrial gamma-ray flashes (TGFs), which emit high-energy radiation from thunderstorms. The team developed an algorithm that accurately reduced the total population of LIS-observed lightning to a much smaller population of candidate TGF-related flashes by looking for unique characteristics within the flashes. ASIM, which can observe TGFs, was used to validate the algorithm. This study is important because instruments like ASIM only observe 300-400 TGFs per year, while LIS observed on average ~1 million lightning flashes per year. This difference of four orders of magnitude in frequency of occurrence means that data-reduction algorithms are necessary to facilitate studying the relationships between TGFs and lightning. In addition, a recent NASA field campaign demonstrated that TGF occurrence may be significantly higher than what can be measured from space, particularly within tropical thunderstorms. Thus, an algorithm that identifies possible characteristics TGF-related lightning may help us later in understanding differences between lightning associated with strong TGFs (observable from space) and lightning associated with weaker TGFs (not currently observable from space).

Services Catalog
The catalogs provide service description, chargeback rate, unit of measure, and service level indicators for each NSSC service.
Service Level Agreement (SLA)
The SLA provides information about roles, responsibilities, rates, and service level indicators for all NASA Centers. The SLA is negotiated on an annual basis in line with the fiscal year. A single SLA is shared by all NASA Centers and signed by the Associate Administrator, Chief Financial Officer, Chief Information Officer, and the Office of Inspector General. The SLA provides for the delivery of specific services from the NSSC to NASA Centers and Headquarters Operations in the areas of:
Financial Management Procurement Human Resources Information Technology Agency Business Services Customer Satisfaction Surveys
The NSSC is fundamentally changing the way NASA does business. In order to maintain customer loyalty and satisfaction, we must not only deliver a higher level of service, but also be customer focused.
