Students gain advanced knowledge of Earth system science by treating the Earth as an integrated system and by applying advanced principles from the natural and social sciences, including chemistry, physics, mathematics, hydrology, meteorology, ecology, economics, sociology, and geographic information systems. Earth system science seeks a deeper understanding of human interactions with the environment that determine the past, present and future states of the Earth and provides a holistic view for understanding the world and a pathway toward sustainability. Students graduate with the qualitative and quantitative skills necessary for employment in environmental risk assessment, public policy, decision-making and sustainability, and geospatial analysis and intelligence.UAH's Atmospheric and Earth Science Department is devoted to providing high-quality education to and to contributing international-caliber research in the areas of remote sensing, atmospheric chemistry and air pollution, radiative transfer, microwave radiometry, severe storms, numerical modeling, and climate-change modeling and measurements.
