SPoRT Science Seminar Series
SPoRT periodically hosts visitors to learn more about our program and team as well as to discuss opportunities for future collaboration. Typically, during these visits, the guest will present a seminar outlining his or her current work to help provide background on common interests. Please check back soon for information on the next seminar.

Total Lightning Highlights Trailing Stratiform Threat for IDSS
Thu, 14 Jul 2016 22:06:48
NWS Huntsville is providing Impact-Based Decision Support Services (IDSS) to protect life and property at an outdoor sporting competition in the Decatur, Alabama area this week. A decaying Mesoscale Convective System (MCS) moved across north Alabama this afternoon, forcing a delay in the competition for several hours. While the North Alabama Lightning Mapping Array (NALMA) [...]
Improving the representation of snow crystal properties within a single-moment microphysics scheme
Single-moment microphysics schemes are utilized in an increasing number of applications and are widely available within numerical modeling packages, often executed in near real-time to aid in the issuance of weather forecasts and advisories. In order to simulate cloud microphysical and precipitation processes, a number of assumptions are made within these schemes. Snow crystals are often assumed to be spherical and of uniform density, and their size distribution intercept may be fixed to simplify calculation of the remaining parameters.
Image of the Day

This four-panel figure from AWIPS II is from 1910 UTC on 20 May 2013, prior to the development of the Moore, OK tornado. The image was taken after the event to evaluate the potential impact of total lightning during the event. The lower two panels show radar observations of storm relative velocity (left) and reflectivity (right). The top panels show two total lightning products. The first is the source density product (left), which is used by several SPoRT partners in operations. The pseudo-geostationary lightning mapper (PGLM – right) is the demonstration product SPoRT is providing to the Hazardous Weather Testbed to demonstrate what the future Geostationary Lightning Mapper observations may look like. The PGLM data are derived from the ground-based lightning mapping array data. In this case it is from the Oklahoma network provided to SPoRT with this collaboration. Lastly, please note the two pop-up windows. These display the output from the Meteorological Development Laboratory’s meteogram tracking tool, which is a time series of the source densities (left) and PGLM (right) observations, respectively. Newcastle and Moore, Oklahoma are circled for reference.
Ingest and Product Status Pages
Though we're not 24/7, SPoRT strives to provide the most timely and reliable data products to its partners and end users. A system has been developed to monitor the health of our real-time data ingest and availability of LDM and FTP products. Summaries are posted every 10 minutes to the links below.
