An Evaluation of the SFR Product during a mid-December Winter Storm for Northern New Mexico
Mon, 15 Dec 2014 21:00:59
The Albuquerque NWS recentlybeganreceiving an updated NESDIS snowfall rate (SFR) product from NASA SPoRT. We were anxious to see how the updated product performed during our most recent winter storm. A fast moving upper level trough and associated Pacific Front blasted into western New Mexico on the afternoon of Saturday, December 13. The upper low [...]
Use of VIIRS Day-Night Band Imagery in Response to Hurricane Sandy Recovery Efforts
In late October 2012, widespread strong winds, torrential rain, coastal flooding, and other effects of Hurricane Sandy contributed to widespread power outages throughout the northeastern United States. In response to this disaster, SPoRT provided SNPP VIIRS day-night band imagery and an experimental, false color blackout composite. SPoRT's experimental "blackout composite" of pre-storm and post-event imagery helped to identify missing lights in a single image. Through collaboration with NASA's Applied Sciences Disasters Program, daily composites were provided to the United States Geological Survey's Hazards Data Distribution System, where they were then distributed to the Department of Defense (DoD) Joint Task Force-Civil Support (JTFCS).

This image shows the response of the low-level atmospheric flow to changes in sea surface temperature (SST). SST differences (in Kelvin) are shown at left, averaged from May 9-19, 2004. 10-m wind convergence differences, shown at right, averaged during the nighttime hours of 05-11 UTC, indicate that the winds slowed down and converged as they moved from the warm Gulf Stream to the cooler coastal waters (see region circled in yellow). This convergence forced vertical atmospheric motion, which encouraged cloud formation.

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 availability of LDM and FTP products and categorize each product based on its age. Summaries are posted every 10 minutes to the link below.
