A collaborative research project between Lewis & Clark College, Pacific
Northwest National Labs, and University of Colorado, Boulder, seeks a
postdoctoral researcher on a project investigating macro-physical
properties of shallow (fair-weather) cumulus clouds.


The work will integrate Total Sky Imager (TSI) visible observations of the
sky dome and observations from active sensors such as radars and lidars
captured at the Atmospheric Radiation Measurement (ARM) Program Southern
Great Plains site. The macro-physical properties, such as cloud base
height, cloud chord length, and cloud aspect ratio, will be used to improve
modeling-based process studies.

The postdoctoral researcher will work primarily at Lewis & Clark College, a
four-year undergraduate liberal arts college located in Portland, OR (
www.lclark.edu) with researcher Jessica Kleiss. Mentoring for a postdoc
interested in exploring a career at a liberal arts college will be
available (but not required). The postdoc will collaborate with researchers
at PNNL and CU Boulder. The postdoctoral researcher will be expected to
spend some months at PNNL in Richland WA each year for closer collaboration
and expanding their professional network. This is a limited duration
position dependent on external grant funding. Two years of support are
expected, with the potential for a third year of research pending adequate

   1. Analyze the Total Sky Imager data and remote sensing (Lidar and
   Radar) data from the ARM field site in Oklahoma to retrieve macrophysical
   cloud properties such as cloud base height, cloud aspect ratio, cloud top
   height, cloud thickness, and cloud chord length. The macrophysical
   properties are then used to inform the 4-D data cube of shallow cumulus
   cloud genesis and evolution.
   2. Keep careful documentation of the analysis procedure through creation
   of readme files and a research notebook.
   3. Contribute to two research progress reports per year for submission
   to DOE / ASR.
   4. Prepare oral or poster presentations to present at roughly one
   professional conference per year.
   5. Participate in collaborative meetings with Kleiss, Riihimaki,
   Kassianov, Long, and undergraduate research students to discuss current
   research progress and next steps.
   6. Maintain computing resources in Kleiss lab: install and update
   software, maintain data backups.
