For over 35 years, the Atmospheric Science Program at Texas Tech University has been dedicated to research of the lower atmosphere.  The main thrust of the program is to develop a better understanding of severe and extreme weather events and, at the same time, educate the next generation of atmospheric scientists. 

The Atmospheric Science Group is physically located on the 12th floor of the Media and Communication building on the Tech campus.  We offer a program of study leading to the Master of Science degree in Atmospheric Science and the Ph.D. degree in Geosciences.  In addition, courses in Atmospheric Science are offered at the undergraduate level to meet the general education requirements of Texas Tech University.  A minor in Atmospheric Science is offered for both B.S. and B.A. students. 

An extensive array of observational and modeling facilities is available to students and faculty, permitting the exploration of a wide variety of meteorological phenomena.  The field facilities are routinely used for data collection in proximity to extreme weather events including tornadoes and hurricanes.
