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."

Tropical Storm Fay during August 2008 affected many areas of the southeastern U.S. with prodigious rainfall amounts in excess of 500 mm, especially from eastern Florida to southwestern Georgia. A high-resolution simulation of the NASA Land Information System (LIS) depicts the dramatic increase in volumetric soil moisture in the root-zone layer (40-100 cm) in the 8 days from 18 to 26 August 2008. This event certainly helped alleviate the multi-year drought over portions of the southeastern U.S.
