LEO Perspective of River-Effect Snow in North Alabama
Wednesday, February 10, 2016
The cold air outbreak over the eastern United States had impacts far and wide, including the development of snow showers all the way into northern Alabama. However, between unseasonably low 850 mb temperatures and northwesterly flow, the outbreak also caused a semi-persistent band of snow to develop along the Tennessee River (downwind of a reservoir known as "Lake Wheeler"). While most of the river-effect monitoring occurred with radar, the late-morning MODIS overpass captured one of the narrow river-effect bands (and did so more effectively than the lower-resolution GOES-East Imagery).
SPoRT Response to Tornado Damage and Recovery in Moore, Oklahoma
On May 20, 2013, the city of Moore, Oklahoma was struck by an EF-5 tornado that devastated a large swath of the community. In response to the event, the SPoRT team developed several products as part of an ongoing feasibility study to examine the utility of NASA, NOAA, and commercial satellite data in responding to disaster events. Immediately following the event, the VIIRS day-night band was used to identify power outages across Moore, Oklahoma and southern portions of Oklahoma City that resulted from the storm. As skies cleared from west to east, cloud-free imagery from the morning of May 21 was compared to the morning of May 20 and difference imagery identified the outage area. SPoRT distributed the VIIRS day-night band imagery through a tiled imagery viewer and shared results with end-user partners and NASA Headquarters management.

SPoRT has partnered with CIRA to transition their total precipitable water (TPW) product to the NWS. TPW is a measure of the amount of water in an entire column in the atmosphere, including near the surface which most conventional water vapor imagery misses, assisting in flood prediction. The image above comes from 19 August 2008 as Tropical Storm Fay crossed south Florida. The purple region to the east of Florida has the greatest water content as was associated with the part of the storm that dumped record rainfall in Melbourne, Florida.
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.
