<div dir="ltr"><div><span style="font-size:12.8px">Overview:</span></div><div><span style="font-size:12.8px">The primary responsibility of the Aircraft Program is to maintain a core set of sampling sites spread over North America using flasks carried in small aircraft. Samples taken from 8 km to the surface are measured for a variety of greenhouse gases and hydro- and halocarbons. Over the last decade the Aircraft Program has moved in many directions, which has allowed us not only to improve our ability to sample the atmosphere but also to focus on specific regions where there is a need for higher spatial and temporal resolution. This expansion in focus includes the development of a new technique for sampling the atmosphere using an AirCore (</span><a href="http://www.esrl.noaa.gov/gmd/ccgg/aircore/" target="_blank" style="font-size:12.8px">www.esrl.noaa.gov/gmd/ccgg/aircore/</a><span style="font-size:12.8px">), as well as instrumentation that will allow autonomous measurements of CO2, CH4 and CO on commercial aircraft. The Aircraft Program also continues to play a major role in regional studies focused on CH4 and CO2 emissions including studies in urban areas, oil and gas producing regions and the Arctic tundra. At the postdoc level, we are looking for someone who is interested in working with data and instruments to help move projects like the AirCore from the experimental stage to one that will allow regular sampling. At the research scientist level, we are looking for someone who is willing to share a variety of responsibilities in the group and to lead some of the efforts such as the regional studies, AirCore research and/or commercial aircraft development.</span><br></div><div><br></div><div>The Position:</div><div>The Cooperative Institute for Research in Environmental Sciences (CIRES) is seeking a Research Scientist and/or Postdoctoral Research Scientist (depending on experience) to support the NOAA/ESRL/GMD/CCGG Aircraft Program. This program, is part of the larger Global Greenhouse Gas Reference Network, which is an international effort to measure greenhouse gases that includes regular, discrete samples from the NOAA/ESRL/GMD baseline observatories, cooperative fixed sites, and commercial ships. The CCGG Aircraft Program’s current focus is on understanding the North American continent’s carbon budget and identifying and understanding carbon sources and sinks on regional and continental scales.</div><div><br></div><div>Duties may include:</div><div>* Support the ongoing acquisition and quality control of in-situ and flask measurements from a network of airborne platforms in North America.</div><div>* Improve techniques, procedures, and instrumentation used in the network, in particular with in-situ measurements of the atmospheric CO2, CH4, CO and possibly other species.</div><div>* Implement field campaigns on behalf of CCGG Aircraft Program within the framework of the North American Carbon Program.</div><div>* Interpret the airborne atmospheric data over North America and the surrounding marine regions to improve understanding of the North American carbon budget and the carbon cycle on regional to global scales.</div><div>* Lead CCGG Aircraft Program’s effort to development of new instrumentation and measurement techniques for use on regularly-scheduled commercial aircraft or development of balloon borne high-altitude sampling system know as the “AirCore”.</div><div>* Publish papers in peer-reviewed journals and present results at scientific conferences.<br></div><div><br></div><div>Preferred Qualifications:</div><div>* PhD in atmospheric physics or chemistry, oceanography, or a related physical science or engineering discipline</div><div>* Demonstrated experience making high-accuracy measurements of trace gases </div><div>* Basic understanding of atmospheric dynamics, particularly boundary layer processes<br></div><div>* Experience with scientific programming <br></div><div>* Demonstrated ability to analyze and interpret atmospheric observational data <br></div><div>* Demonstrated ability to communicate results in a clear fashion to the scientific community via peer-reviewed publications and presentations at scientific meetings</div><div>* Willing and able to fly on research aircraft</div><div>* Demonstrated ability to work in a collaborative environment</div><div><br></div><div>To apply, send a CV and cover letter to <a href="mailto:esrl.gmd.jobs@noaa.gov">esrl.gmd.jobs@noaa.gov</a> for consideration.
