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."

Very windy and dry conditions developed across New Mexico on 29 April 2010. The MODIS 1km visible satellite image captured at 2008Z on the 29th shows a thick white dust plume over northwest Otero County surging northeast toward Lincoln County. The dust plume thins out as it continues to the northeast across northern Chaves and southeastern De Baca Counties. Surface observations 60 miles northeast of White Sands at the Sierra Blanca Regional Airport reported visibilities below 3 SM between 1835Z and 0115Z. The visibility was as low as 3/4 SM a few hours after a peak wind gust of 67 knots. Surface observations more than 200 miles northeast of White Sands at Clovis, NM reported visibilities of 1 ½ SM at 2235Z with peak wind gusts of 50 knots.
