Scientist II, Georgia Institute of Technology, 05/2006 --
Postdoctoral
Associate,
±
Participated in a data-assimilation project
to build up an assimilation system for combing in situ surface flux
observations into a land surface model. My major task is to develop the adjoint
code of a complicated land model (> 10,000 lines of source code). I
accomplished this task using a source-to-source translator of
automatic-differentiation software, the Tangent and Adjoint Model Compiler
(TAMC). I also included the assimilation system several other optimization
methods including pattern search, simplex search and directional search methods
for evaluation and comparison purposes.
±
Conducted
statistical data analysis to in situ observational data for preparing data
source for the developed assimilation system.
Research Assistant, Georgia Institute of Technology,
01/2000 -- 05/2004
±
Extended the latest CCSM land model with explicit
parameterizations of the terrestrial ecosystem carbon and nitrogen processes
and studied the short-term interactions between the atmosphere and the
terrestrial ecosystem.
±
Introduced a new soil hydraulic scheme into a climate land surface
model to include the effects of soil structure on soil hydraulic properties. I
found that the soil structure influence can at least explain part of the common
simulation biases of surface hydrology in areas with specific climate and
ecosystem features.
