Atmospheric scientists and meteorologists study the physics and chemistry of the atmosphere. This discipline requires heavy concentrations in physics and advanced mathematics, and the best prepared students have a strong background in both. Scientists in this field use knowledge about the atmosphere to predict weather, perform long-range forecasting, apply numerical modeling, evaluate climate change, and probe atmospheric chemistry and asses air quality. Atmospheric Sciences and Meteorology programs also include coursework in remote sensing and environmental studies and interdisciplinary applications with oceanography and hydrology. Graduate students have extraordinary opportunities to participate in groundbreaking research that contributes to regional, national, and international programs.
