Our work primarily deals with the observation-based study of the troposphere and its dynamics. We look at the thermodynamic and dynamic nature of the troposphere and its cloud initiating capacity as it impacts us, those who live in it. As such, the group works with operational instrumentation, new techniques for analysis of observation data, and modeling work that tests and advances the physics of the model construct. The characterization of instrument errors and how they impact the observation and the weak climate signal that would be derived, the trace gas and resulting human health impacts, and regional distribution of the instrumentation in capturing the dynamic scale-variability and its impact in-network observation design is also of interest.
