Dr. Alex B. Guenther, a renowned scientist in land ecosystem and atmospheric research, has joined the Pacific Northwest National Laboratory to lead research in the interactions
between terrestrial systems and climate.

In physical geography, a wetland is an environment at the interface
between terrestrial ecosystems and aquatic
systems.
The research, which was funded by the Royal Society, forms part of a broader programme of study challenging the traditional division
between marine ecology and «mainstream» ecology, the notion that marine
systems are somehow fundamentally different from
terrestrial systems, and that this demands separate research approaches and indeed research institutes — to study them.
Pat's general research interests include (1) the evolution of birds, (2) the relationship
between osteological features and different soft - tissue
systems (e.g., pulmonary, neurosensory), and (3) the biogeographic history of
terrestrial vertebrates on Gondwanan landmasses during the latter half of the Mesozoic.
Modelling interactions
between terrestrial and atmospheric
systems requires coupling successional models to biogeochemical models and physiological models that describe the exchange of water and energy
between vegetation and the atmosphere at fine time - scales.
Immediate challenges that confront models of the
terrestrial - atmosphere
system include exchanges of carbon and water
between the atmosphere and land, and the
terrestrial sources and sinks of trace gases.
Once CO2 has been emitted into the atmosphere, the carbon cycle will redistribute it
between the atmosphere, oceans, and
terrestrial biosphere, but it will not disappear from those
systems for thousands of years.
That is determined by consideration of the absorption of the atmosphere of
terrestrial radiation (and radiation emitted by the atmosphere), which essentially ends up determining at what altitude the temperature has to be determined via radiative balance
between the Earth
system (earth + atmosphere) and the sun and space [which for the earth
system with its current albedo is ~ 255 K].
My research interests aim in understanding the role aerosols play in the Earth
system, by studying the interactions and feedbacks
between the atmosphere, the
terrestrial biosphere, the ocean, and climate.
