We seek a postdoctoral scientist who will be supported for two years by
a DOE-
funded collaborative EaSM project at the Pacific Northwest National
Laboratory (PNNL)
in Richland, Washington.

Project Description:

The aerosol indirect effect (AIE) remains one of the largest
uncertainties in global
climate models. The goal of this project is to systematically quantify
some of the major
uncertainties in the AIE associated with: 1) the treatment of
cloud-scale turbulence that
drives aerosol activation, 2) cloud macrophysics and microphysics, 3)
processes, and 4) thermodynamic feedbacks. The NCAR Community Atmospheric
Model version 5 (CAM5) will be used in this project, which includes
advanced treatments
for aerosols, clouds, turbulence and their interactions. CAM5 will also
be used in its
coupled configuration as the Community Earth System Model (CESM1) to explore
consequences of the AIE to the coupled system.

Position Description:

The Postdoctoral Fellow will be supervised by Dr. Xiaohong Liu and Dr. Phil
Rasch at PNNL. The candidate will have an opportunity to visit the
National Center for
Atmospheric Research (NCAR) in Boulder, Colorado, for 3-6 months to work
closely with
the other project member Dr. Sungsu Park at NCAR.


The candidate should have a Ph.D. degree in atmospheric sciences or related
field and is expected to be a strong modeler with experience in running
and analyzing
model output. The candidate is also expected to have expertise in
aerosol and/or cloud
microphysics processes, and their interaction with climate. The research
emphasis will
be on (1) investigating how aerosol processes, aerosol-cloud
interactions (e.g., cloud
droplet activation and ice nucleation), and cloud microphysical
processes influence AIE,
and (2) exploring the role of aerosol and cloud microphysics processes
important to AIE
on decadal climate variability in the coupled system.

Applicants should send (1) a curriculum vitae, (2) 1-2 page statement of
interests, and (3) the names and contact information of 3 references to
Dr. Xiaohong Liu
(email: <>). For more information, please contact
Xiaohong Liu by
email or phone (509-372-4528). Initial consideration will be given to
received prior to April 1, 2011. Thereafter, applications will be
reviewed on an as-
needed basis.
