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.

April 27, 2011–Five Years Later: A Satellite Imagery Perspective
Tue, 26 Apr 2016 14:00:22
On April 27, 2011, a severe weatheroutbreak occurred across the southeastern United States, resulting in 199 tornadoes across the region and over 300 fatalities (NWS 2011 Service Assessment). Alabama was among the states hardest hit,with 68 tornadoes surveyed by the National Weather Service (NWS)Weather Forecast Offices (WFOs)in Huntsville, Birmingham, and Mobile, Alabama, and over 250 [...]
Evaluation of enhanced high resolution MODIS SSTs and the impact on regional weather forecasts
The NASA Short-term Prediction Research and Transition (SPoRT) Center currently produces a high resolution sea surface temperature (SST) product for use by National Weather Service (NWS) Weather Forecast Offices (WFOs) as an operational diagnostic and also as input for their weather forecast models. This product uses Moderate Resolution Imaging Spectroradiometer (MODIS) data to produce composite SST output with spatial resolution superior to other SST data used to initialize regional weather forecast models. A six month study from February to August 2007 over the marine areas surrounding southern Florida was conducted to compare the use of the MODIS SST composite versus the Real-Time Global SST analysis to initialize the Weather Research and Forecasting (WRF) model.
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.
