University Corporation for Atmospheric Research

Postdoctoral Fellow in Climate & Global Change

Climate & Global Change Laboratory

What You Will Do:

The focus of this postdoctoral fellow position will be on land-atmosphere coupling processes and, in particular, on how various new features introduced in CLM5 impact on the simulation of drought within Community Earth System Model (CESM). The successful candidate will conduct idealized simulations and diagnostic analysis of model simulations and observational products to investigate the feedback processes and pre-conditioning factors that impact drought severity. They will use a constrained circulation ensemble (CCE) approach to generate ensembles of atmospheric circulation induced drought events. They will systematically investigate the influence of processes that are at the forefront of our modeling capabilities such as plant hydraulics, irrigation, wildfire and dynamic vegetation feedbacks within the context of these CCE’s, both in the present day and future climate. They will synthesize these investigations into an improved understanding of the origins and projected changes in drought and will, for the first time, quantify, in a controlled and systematic manner, the impact of land-atmosphere coupling processes that are at the forefront of our modeling capabilities.

This position includes the design and execution of idealized experiments with the Community Earth System Model, as well as scientific and statistical analysis of the model output along with analysis of observation based products to assess the model’s credibility. In addition, the postdoctoral fellow will be expected to present their research at scientific meetings and publish their results in peer-reviewed articles.

While the postdoctoral fellow is expected to operate with a significant degree of independence, they are expected to collaborate with a broad group of researchers within the Climate and Global Dynamics Laboratory with expertise in climate analysis and land surface modeling to achieve the deliverables of this NOAA MAPP-funded project.


Perform idealized experiments and analysis to investigate the role of land-atmosphere coupling processes in the simulation of drought. Conduct analysis of existing CESM simulations (large ensembles) to identify target drought events and assess differences between CESM2 and CESM1 in the representation of drought. Take the lead and participate in writing of scientific journal articles and formal reports. Present results at relevant meetings.

What You Need:

Education and Years of Experience
A Ph.D. or equivalent experience in climate sciences; demonstrated understanding of climate dynamics with a particular emphasis on land-atmosphere coupling processes and the dynamics of drought; research experience in a relevant field, with contributions to refereed journals.

Knowledge, Skills, and Abilities
Expertise in some of the following areas:

  • Climate dynamics, in particular on drought related processes and land-atmosphere interactions.
  • Earth System Modeling, in particular the modeling of land surface processes and the coupling between the land surface and the atmosphere.
  • Working with large geophysical datasets, including Earth System Model output.
  • Diagnostic interpretation of climate-related processes.
  • Statistical analysis of large geophysical datasets.

Also Desirable:

  • Strong written and oral communication skills, especially for scientific publications and presentations.
  • Ability to work both independently and as part of a collaborative team.
