This position is for a Postdoctoral Associate with the Cooperative
Institute for Research in Environmental Sciences (CIRES) at the
University of Colorado in Boulder, Colorado, and the Carbon Cycle
and Greenhouse Gases (CCGG) division of NOAA Global Monitoring
Laboratory. We are seeking a post-doctoral candidate to implement
methane and its isotopologues, both δ¹³C-CH₄ and δD-CH₄, in a
global atmospheric model, with the end goals of (1) Improving our
understanding of the methane budget from atmospheric measurements
of CH₄, δ¹³C-CH₄ and δD-CH₄, and (2) Designing future atmospheric
measurement networks for these tracers.
The University of Colorado Boulder is committed to building a
culturally diverse community of faculty, staff, and students
dedicated to contributing to an inclusive campus environment. We
are an Equal Opportunity employer, including veterans and
individuals with disabilities.
Who We Are
is an internationally recognized
leader in innovative environmental science and research and is
located at the University of Colorado Boulder. At CIRES, more than
950 environmental science professionals work to understand the
dynamic Earth system, including people’s relationship with the
planet. CIRES has partnered with NOAA since 1967, and our areas of
expertise include weather and climate, changes at Earth’s poles,
air quality and atmospheric chemistry, water resources, solid Earth
sciences, and more. Our vision is to be instrumental in ensuring a
sustainable future environment by advancing scientific and societal
understanding of the Earth system.
NOAA Global Monitoring Laboratory
The Carbon Cycle and Greenhouse Gases (CCGG) division of NOAA
Global Monitoring Laboratory (GML) has been operating a cooperative
global network of atmospheric CH₄ measurements since 1983. These
measurements are the most fundamental means of tracking long-term
changes in global CH₄ abundance and emissions. A subset of the air
samples that provide these CH₄ measurements are also analyzed for
isotopologues of CH₄, namely δ¹³C-CH₄ and δD-CH₄, in collaboration
with the Institute of Arctic and Alpine Research (INSTAAR) at the
University of Colorado Boulder. These measurements are difficult
but provide additional information about methane sources that
traditional CH₄ measurements do not.
In previous work, GML scientists and collaborators implemented CH₄
and δ¹³C-CH₄ in the 3D tracer transport model TM5 to attribute the
post-2006 growth in atmospheric methane to different source
sectors. The post-doctoral candidate will incorporate δD-CH₄ in
this model to further investigate the role of atmospheric sinks,
and the relative contribution of natural versus anthropogenic
microbial emissions, to the post-2006 CH₄ growth. The candidate
will run OSSEs to determine the optimal sampling strategy for
making CH₄, δ¹³C-CH₄ and δD-CH₄ measurements in the future that
provide the best information to decipher the global methane
What Your Key Responsibilities Will Be
What You Should Know
- Carry out atmospheric transport simulations of methane and its
isotopologues under various emission scenarios to determine which
scenarios are consistent with atmospheric measurements over years
- Perform observing system simulation experiments (OSSEs) to
design a future sampling network that will maximize the information
derived from a limited number of methane and isotopologue
- Collaborate with scientists in NOAA, CIRES, INSTAAR (Institute
of Arctic and Alpine Research) and other partner organizations to
synthesize research results into meaningful scientific
