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.

Dust Storm Shown by VIIRS and MODIS in Southwest 2014
Wed, 12 Mar 2014 04:37:12
In the southwest CONUS region, severe to extreme drought conditions exist in many areas. In particular southwest Colorado, northeast New Mexico and the Texas and Oklahoma panhandle areas are very dry according to the U.S. Drought Monitor. A building high pressure area developed a strong pressure gradient across these areas during the afternoon of 11 [...]
Product Status Page
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.

This is an example of the MODIS “Nighttime Microphysics” red-green-blue (RGB) composite image displayed in N-AWIPS. The product is derived from MODIS using guidelines developed by EUMETSAT. In this particular image the combination of multiple channels better discriminates fog in the Southeast (blue) from low clouds streaming off the Great Lakes (yellow-greens). This offers more detail than the standard MODIS spectral difference (or fog) product that would show both of these regions as yellow.
NWS Albuquerque Fog Product Evaluation
The Albuquerque National Weather Service Forecast Office recently evaluated the SPoRT MODIS fog product, also known as the spectral difference, as well as the GOES low cloud base and fog depth products. The Aviation forecaster on the morning of 7 January 2009 used these products to assist in producing and modifying the terminal aerodrome forecast (TAF) for two regional airports: Farmington and Gallup. The main issue was a concern about the validity of the timing of fog at each TAF site in the model guidance for these observation sparse locations. The SPoRT products were valuable, and the Aviation forecaster said, "Seeing where the lower clouds and fog were developing through the evening in the imagery made me much more confident if lower clouds and / or fog did occur, it woud not be until 10Z or after, as remained forecasted in the 06Z TAF."
