CIRES/ NOAA NCEI Post-Doc in Geomagnetism Research

Requisition Number:



Boulder, Colorado

Employment Type:

Research Faculty



Job Summary

The Cooperative Institute for Research in Environmental Sciences (CIRES) at the University of Colorado in Boulder, Colorado is seeking a Post-doctoral research scientist to work in the NOAA National Centers for Environmental Information (NCEI) Geomagnetism group. The goal of this research project is to better separate rapid magnetic field variations originating in the Earth’s outer core from effects of external magnetic sources.

The successful applicant will collaborate with scientists from NCEI Geomagnetism on developing a new data-based model of the magnetospheric magnetic field near the Earth’s surface, from a combination of low Earth orbit satellite (including the European Space Agency Swarm tri-satellite mission) and ground observatory data. The obtained model will then be used to extract rapid core field variations from both satellite and observatory records, and investigate their spatio-temporal characteristics over several decades. Improved observations and models of rapid core field variations are expected to better constrain physics-based models of the geodynamo and further our understanding of deep Earth dynamics. 

Who We Are

At CIRES, the Cooperative Institute for Research in Environmental Sciences, more than 800 environmental scientists work to understand the dynamic Earth system, including people’s relationship with the planet. CIRES is a partnership of NOAA and the University of Colorado Boulder, and our areas of expertise include weather and climate, changes at the Earth’s poles, air quality and atmospheric chemistry, water resources, and solid Earth sciences. Our vision is to be instrumental in ensuring a sustainable future environment by advancing scientific and societal understanding of the Earth system.

What Your Key Responsibilities Will Be

  • Develop and implement a strategy to model the Earth’s magnetospheric field near the Earth’s surface, including the time-varying longitudinal asymmetry.
  • Invert satellite and observatory datasets for source parameters representing the geomagnetic magnetospheric and core fields.
  • Investigate rapid core field variations in satellite and observatory records.

What You Should Know

This position will be rostered in CIRES at the University of Colorado Boulder, but will be physically situated in the David Skaggs Research Center, 325 Broadway, Boulder, CO 80305.  If you are the selected finalist you will be required to pass a federal laboratory background clearance for site access.
