[Met-jobs] Research Associate in Carbon Cycle Science - Dept of Meteorology - PennState University

Date Mon, 6 Apr 2015 18:41:52 -0400 (EDT)

Research Associate position in Carbon Cycle Science - Dept of Meteorology - 
PennState University


One or more research associate positions are available in the study of the 
fluxes and transport of greenhouse gases. The positions will focus on analyses 
of airborne measurements intended to quantify and reduce uncertainty in 
atmospheric inversions caused by atmospheric transport, and improve 
quantification of regional-scale CO2 and CH4 emissions. The successful 
candidates will analyze aircraft data with an ensemble numerical modeling 
system incorporating uncertainties in both atmospheric transport and greenhouse 
gas fluxes and boundary conditions. The work will contribute to the Atmospheric 
Carbon and Transport – America (ACT-America) study, a 5-year, NASA-funded Earth 
Venture Suborbital mission led by Profs. Kenneth Davis and Thomas Lauvaux. 
Research flights are scheduled to begin in the Winter of 2016. The successful 
candidates should have a strong background in one or more of the following 
areas: numerical weather modeling and data assimilation, statistics, inverse 
methods, carbon cycle science, boundary layer meteorology and aircraft data 
analyses. Strong communications skills, a Ph.D. in atmospheric sciences or a 
related field, and at least 2 years of postdoctoral research experience are 
required. The ability to contribute to research and data management, and to 
assist project graduate students and postdoctoral fellows is beneficial. This 
is a fixed-term appointment for one year from date of hire with strong 
potential for continued support. The positions are available beginning July 
2015, and will remain open until filled. The salaries will be commensurate with 
experience, and will comply with The Pennsylvania State University guidelines. 

To apply, please upload a current CV, a cover letter, the names and addresses 
of three references, and a brief statement of research interests and long-term 
goals at:

Applications received by April 27, 2015 will receive full consideration.

The Atmospheric Carbon and Transport – America project

The ACT-America project focuses on 1) improving the atmospheric transport of 
greenhouse gases over North America; 2) improving regional-scale estimates of 
CO2 and CH4 fluxes using atmospheric inversion techniques; and 3) evaluating 
the sensitivity of the Orbiting Carbon Observatory (OCO-2) column CO2 
measurements to regional variability in tropospheric CO2. These goals define 
the baseline mission and address the three primary sources of uncertainty in 
atmospheric inversions: atmospheric transport, prior flux estimates, and sparse 
atmospheric CO2 and CH4 (hereafter C) data. ACT-America will achieve these 
goals by deploying airborne and ground-based platforms to obtain data that will 
be combined with data from existing measurement networks and integrated with an 
ensemble of atmospheric inversion systems. Aircraft instrumented with remote 
and in situ sensors will observe how midlatitude weather systems interact with 
C sources and sinks to create atmospheric C distributions. It will be the first 
mission ever to focus on improving atmospheric inversions via studying synoptic 
scale atmospheric transport, and will provide unique and direct evaluation of 
the high-resolution performance of OCO-2 observations. The ACT-America schedule 
includes a 1-year preparation and integration phase, five 6-week campaigns 
across four different seasons and 3 years, and one year dedicated to analyses. 
Each campaign will yield progress towards the three mission goals, and these 
results will be integrated to achieve the overall goal in the final year of the
