Field Projects

Although models, theoretical studies and laboratory work play a major role in the atmospheric sciences, ultimately new theories and model simulations must be tested and evaluate through observations of the state of the atmosphere. The work of Prof. McFarquhar’s group at the University of Oklahoma has concentrated on using observations and multi-scale models in combination in order to improve the representation of clouds in weather and climate models. The measurements are made using aircraft to fly through clouds, measuring the microphysical properties of clouds in-situ. Because cloud properties vary considerably depending upon formation mechanism, height and geographic location, field experiments have been conducted in a wide variety of locations (illustrated above) to better understand what causes variability in cloud properties.
