We study the
interactions between climate change and biogeochemical cycles, and focus on the
processes that maintain and alter the composition of the atmosphere, and hence
the climate.
A question driving my
research is how will atmospheric CO2 and climate co-evolve, and what we can do
about it. We continue to analyze atmospheric, land and ocean observations
pertinent to the carbon cycle, and to synthesize them in atmospheric transport
models to infer how CO2 sources and sinks have been changing. We are also using the coupled
carbon-climate model at NCAR to project how land and ocean carbon sinks will
change with accelerating global warming and with human activities. A not surprising finding is that the
droughts have diminished, and will continue to diminish, the land uptake of
CO2.
Our group has taken
several approaches towards the hydrologic cycle. We have incorporated water isotopes into the NCAR
atmospheric general circulation model to diagnose the water cycle. Dust links the carbon cycle and the
hydrologic cycle, as dust arises from (certain) arid regions, their deposition
to the ocean stimulates marine productivity (at least for 1-2 weeks), and they
reflect and absorb radiation. To
understand the life cycle of water itself and how plants both respond to and
change the water in the soils, we have embarked on a new and exciting project –
the HydroWatch Project - to
monitor and model water in the atmosphere, trees, soils, rock fractures and
streams. Our first deployment (in October 2007) was at the Eel River at the
Angelo Coast Reserve, one of the UC Natural Reserves.
A new satellite, the
Orbiting Carbon Observatory (OCO) is scheduled for launch in late 2008. OCO will collect an unprecedented
volume of data on the CO2 mixing ratio in the atmospheric column. In collaboration with Eugenia Kalnay
(U. Maryland), we plan to assimilate the OCO data in conjunction with
meteorological observations into the global carbon-climate model. The goal is to use OCO data to
constrain estimates about processes that exchange CO2 between the atmosphere
and the surface (land and oceans).
