Trumbore / Czimczik Research Group

The focus of my research is the cycling of carbon and nitrogen in the terrestrial biosphere. I am particularly interested in understanding how climate change and alterations in land use and management as well as in the frequencies of disturbances (i.e. drought, fire) affect the allocation and residence time of carbon and nitrogen in soils and perennial plants. And, how changes in terrestrial ecosystems feed back to the climate system, e.g. by constraining future levels of greenhouse gases in the atmosphere.

Simulation of the physical, chemical and biological processes that determine atmospheric composition. Development of

  1. detailed numerical models of photochemistry and atmospheric radiation, and
  2. global chemical transport models that describe ozone and other trace gases.

Studies include the predicted effects of volcanic sulfate aerosols on stratospheric ozone loss, the role of clouds in scattering sunlight and altering photochemistry, and the non-linearities in chemical systems that lead to sudden changes such as the depletion of ozone caused by CFC increases.

The oceans produce a diverse array of trace gases that affect the chemistry of the atmosphere and the climate system. Our goal is to understand what controls the production, emissions, and atmospheric chemistry of oceanic trace gases. We develop trace gas detectors, collect field data from islands and ships and use computer models to simulate natural processes.

Zender Modeling Lab

Our research group studies the energy and trace species that pass through Earth's atmosphere. We model the microphysics of trace gas, aerosol, cloud, and surface interactions with Earth's radiative, thermodynamic, and chemical budgets. We then (often) parameterize these effects in climate models. The model simulations, combined with lab, field, and satellite data, help us attribute alteration of Earth's climate and composition to specific processes. Our current research includes mineral dust, meteoric, and carbonaceous aerosols, snow lifecycle and albedo, aerosol impacts on ocean biogeochemistry, wind-driven surface energy/mass exchange, climate-disease links, and terascale data analysis. Our aerosol generation, radiative transfer, and data processing models are freely available and are used in geoscience research institutions world-wide.

We are exploring interactions between biosphere-atmosphere-human, specifically, how the interactions affect on the oxidation capacity of the troposphere that controls fates of trace gases and secondary photochemical product (e.g ozone and secondary aerosols) productions. Our research tools are mainly in-situ measurement instrumentation to precisely quantify very reactive radical species in the troposphere and we deploy the instrumentation to the environmentally critical locations.
