An expert in the Department of Atmospheric Sciences in the Texas A&M University College of Geosciences is available to discuss with media the massive plume of Saharan dust that is forecasted to arrive above Texas late this week.

Timothy Logan, assistant professor of atmospheric sciences and director of the Houston Lightning Mapping Array Network, is an expert in aerosol-cloud interactions, aerosol chemistry and biomass burning smoke.

Logan uses the Texas A&M Center for Atmospheric Chemistry and Environment’s state-of-the-art Micropulse Lidar (Light Detection and Ranging Instrument) to study particles in the atmosphere. He can discuss the science behind how Saharan dust moves through the atmosphere and how it affects the weather.
