My PhD Thesis was "Satellite Observations of C2H2 and C2H6 in the Upper Troposphere", where I developed retrievals for these biomass-burning emitted species from the MIPAS satellite instrument (Parker, 2010 (Thesis), Parker et al., 2011). These data showed the distinctive nature of C2H2 distributions, confirmed in greater detail than previously possible features of hydrocarbon enhancements in the upper troposphere and highlighted the future use of MIPAS hydrocarbon data for testing model transport and OH decay regimes in the middle to upper troposphere.

My career since has focused extensively on developing retrievals for the remote sensing of greenhouse gases from satellite instrumentation and their use in improving our understanding of the carbon cycle. In particular, I have developed retrievals for  the Japanese GOSAT satellite (Parker et al, 2011, Parker et al, 2015). These GOSAT retrievals of CO2 and CH4 are now routinely delivered to the ESA GHG-CCI project and the Copernicus Climate Change Service.

I have held an ESA-CCI Living Planet Fellowship (2015-2017) focused on ExpLoring thE Global cArbon CyclE through atmospheric GreenHouse Gas variability (ELEGANCE-GHG). This involved studying the GHG emissions over Indonesia during the 2015 El Nino event (Parker et al., 2016) and evaluating the year-to-year anomalies in tropical CH4 emissions (Parker et al, 2018).

My current work involves evaluating and analysing carbon cycle processes in Earth System Models, working as part of the UK Earth System Model Core Group, led by NCAS/Met Office.
