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.

Observations of NUCAPS Soundings in the TN Valley — 20 July 2016
Mon, 25 Jul 2016 04:33:03
So, recentlyI've had the opportunity to use and evaluate soundings from the NOAA Unique Combined Atmospheric Processing System (NUCAPS). These soundings, produced by the ATMS and CrIS instruments onboard the Suomi NPP satellite, are available in AWIPS generally twice per day over any given location. A couple of advantages of the NUCAPS soundings is they're [...]
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.

This MODIS snow/cloud RGB composite combines reflected solar radiation from visible and near-infrared channels to distinguish between cloud cover (white), clear ground (green), and snow cover (shades of red). This image from 12 December 2008 shows snow through northwest Alabama and central Tennessee. Snow was even on the ground in Louisiana. Additionally, breaks in the clouds show that snow had accumulated in Kentucky as well.
