Experimental forecast of dust from the Sahara Desert
The coupled global weather and chemistry research model, dubbed FV3-Chem, produces seven-day forecasts for a host of air quality impacts, including where dust will deliver hazy days and colorful sunsets, as well as potential breathing problems and other respiratory issues for sensitive populations. This video shows a forecast of dust from the Sahara Desert reaching the southeast U.S. by May 21.
FV3-Chem is being developed by GSL and other partners. It forecasts the distribution of some primary air pollutant - smoke, soot, organic carbon, sulfate, and large and small particles of dust and sea salt - collectively known as aerosols. Because these aerosols affect the weather, the model also provides weather forecasts.
