Full-Time Close All Job SummaryThe 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 project is to investigate the feasibility of calculating accurate models of Earth’s core geomagnetic field from fluxgate magnetometer data collected onboard current satellite platforms, including the Iridium satellite constellation. Global core field models are used in various scientific fields (e.g., geomagnetism, deep Earth research, and space physics) and technological applications (e.g., magnetic field-based navigation). Examples of such models include the World Magnetic Model and the International Geomagnetic Reference Field. The successful applicant will collaborate with scientists from NCEI Geomagnetism and Johns Hopkins University Applied Physics Laboratory (APL) to determine and apply temperature corrections to the magnetic data, investigate and mitigate noise sources such as spacecraft fields, determine satellite attitude from other onboard sensors such as star cameras, calibrate the magnetic data, and finally build models of Earth’s core field from the calibrated data. Modeling improvements will be explored by using data from multiple satellites and possibly incorporating additional data from ground-based observatories. The position is located in Boulder, Colorado. Salary will be commensurate with experience.Who We AreAt 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.
NOAA's National Center for Environmental Information (NCEI) is responsible for preserving, monitoring, assessing, and providing public access to the Nation's treasure of geophysical data and information. Your Key Responsibilities Will Be
  • Characterize noise sources in satellite magnetic field data and develop strategies to model and mitigate these noise sources.
  • Perform calibrations of satellite magnetic field data.
  • Invert calibrated datasets for source parameters representing the geomagnetic core field.
What You Should KnowCIRES commits to inclusive excellence by advancing equity and diversity in all that we do. We are an Affirmative Action/Equal Opportunity employer, and particularly encourage applications from members of historically underrepresented racial/ethnic groups, women, individuals with disabilities, veterans, LGBTQ community members, and others who demonstrate the ability to help us achieve our vision of a diverse and inclusive community.
This position is rostered in CIRES at the University of Colorado Boulder, but will physically work in the David Skaggs Research Center (NOAA), 325 Broadway, Boulder, CO, 80305, a Federal facility. You must be able to pass a federal security check to be granted access to the building.
Travel is required for this position at 1-2 trips per year.
