Postdoctoral Research Associate - Atmospheric Sciences

Job ID 2893 Date posted 11/04/2021

Brookhaven National Laboratory ( delivers discovery science and transformative technology to power and secure the nation’s future. Brookhaven Lab is a multidisciplinary laboratory with seven Nobel Prize-winning discoveries, 37 R&D 100 Awards, and more than 70 years of pioneering research. The Lab is primarily supported by the U.S. Department of Energy’s (DOE) Office of Science. Brookhaven Science Associates (BSA) operates and manages the Laboratory for DOE. BSA is a partnership between Battelle and The Research Foundation for the State University of New York on behalf of Stony Brook University. BSA salutes our veterans and active military members with careers that leverage the skills and unique experience they gained while serving our country. Our organization fully supports service members transitioning from active duty to civilian life and pledge’s our commitment to actively hire veterans of the U.S. Armed Forces. Military personnel who have been formally trained or have relevant experience obtained while in service may meet educational requirements and are encouraged to apply for job opportunities at BSA.

Organizational Overview

The Environmental & Climate Sciences Department ( at Brookhaven National Laboratory focuses on a wide range of theoretical, experimental, and field studies in support of the U.S. Department of Energy's climate and energy research agendas. Work is supported by the Atmospheric Radiation Measurement (ARM) User Facility (, an observations-based program that measures aerosols, clouds, precipitation, radiation, and atmospheric dynamics; the Atmospheric Systems Research Program (; and the Terrestrial Ecosystems Science Program ( This work is pursued with the ultimate goal of improving predictability and reducing the uncertainty in global and regional climate models. The department research portfolio also includes development of environmental technologies and applications for renewable energies, urban science, and national security.

The Environmental & Climate Sciences Department (ECSD) seeks to gain improved understanding--through remote sensing, process-level theory and analysis, and modeling studies--of the microphysical and dynamical processes that impact the lifecycle of clouds to improve their representation in climate models and increase our ability to understand and project global change. We are also interested in the development of novel instrumentation to address existing shortcomings of our surface-based observatories. Some of these shortcomings are related to the need for higher resolution measurements at the cloudy-clear air interface using state-of-the-art radar and lidar sensors with sub-meter to a few cm resolutions. In addition, we are interested in evaluating these technologies in a controlled environment such as a cloud chamber.  

Position Description
The Environmental & Climate Sciences Department (ECSD) has an opening for a Postdoctoral Research Associate. In this role you will work with a team of scientists in the Environmental & Climate Sciences Department, the Center for Multiscale Applied Sensing ( and the Radar Science group at Stony Brook University ( on the research, development and deployment of novel, ultra-high resolution sensors for aerosol-cloud-precipitation studies in the real atmosphere and in controlled environment (i.e. cloud chamber). A successful candidate will have a strong interest in the use of observational datasets for the study of cloud microphysics and dynamics and their interaction with the free atmosphere. This position has a high level of interaction with an international and multicultural scientific community.

Essential Duties and Responsibilities:

  • Examine the microphysical and dynamical processes that affect boundary layer clouds using observations and/or modeling.
  • Design high-resolution remote sensing techniques for chamber and atmosphere observations.
  • Publish and present research results at national and international venues.

Position Requirements
Required Knowledge, Skills, and Abilities:

  • Ph.D. in meteorology, atmospheric science, or a closely related field
  • Demonstrated experience in understanding processes that control clouds and/or aerosol-cloud interactions
  • Clear and concise verbal and written communication and collaboration skills

Preferred Knowledge, Skills, and Abilities:

  • Experience with remote sensing instrumentation for clouds and precipitation (e.g., cloud radar, passive or active satellite sensors)
  • Experience with instrument simulators
  • Experience with machine learning techniques
  • Experience with atmospheric modeling at LES or cloud-resolving scales
  • Strong programming skills, such as a familiarity with data analysis software (e.g., Python, IDL, MATLAB, FORTRAN)


  • BNL policy requires that after obtaining a PhD, eligible candidates for research associate appointments may not exceed a combined total of 5 years of relevant work experience as a post-doc and/or in an R&D position, excluding time associated with family planning, military service, illness or other life-changing events.
  • Review of applications begins immediately. Applications will be accepted until the position is filled.
  • The initial term appointment will be one year, subject to renewal contingent on funding and performance.
  • Research will be under the direction of Dr. Pavlos Kollias.

At Brookhaven National Laboratory we believe that a comprehensive employee benefits program is an important and meaningful part of the compensation employees receive. Our benefits program includes, but is not limited to:

  • Medical, Dental, and Vision Care Plans
  • Flexible Spending Accounts
  • Paid Time-off and Leave Programs (vacation, holidays, sick leave, paid parental leave)
