Full-column Greenhouse Gas Sampling 2012-2014

13 January 2012 - 28 February 2014

Lead Scientist: Marc Fischer

Observatory: SGP (Southern Great Plains)

ARM-SGP has become a de facto focal point for evaluation of new remote sensing instruments that determine GHG mixing ratios from the ground, airborne, and satellite platforms. These activities all require validation against in situ measurements of the vertical profiles of GHG mixing ratios. For example, ARM Aerial Facility (AAF) measurements have been used to evaluate measurements made by the Cal Tech Fourier Transform Spectormeter (FTS) as part of the TCCON network (Wunch et al, 2010), NASA Tropospheric Emission Sounder (TES) CO2 retrievals (Kulawik et al,., 2010), prototype Lidar instruments for the NASA Accends mission (Abshire et al., 2010), and is expected to play a key role in future evaluations of both Japanese GOSAT retrievals of CO2 and CH4, and NASA Orbiting Carbon Observatory data (launch expected in February, 2013). Hence, this IOP will directly support both carbon cycle science being conducted by the DOE ARM/LBNL Carbon Project and a large component of the other major GHG remote sensing missions concerned with accurate assessment of the radiative forcing derived from atmospheric GHGs.
