Deputy Science Leader, Atmospheric Scientist: VC
I am deputy science leader of the Atmosphere, Ice and Climate team and an atmospheric physicist. I work within the Climate Processes group (part of AIC). I have worked at BAS since 2006 and my main area of research is the study of atmospheric gravity waves as a dynamical vertical coupling mechanism in the polar regions. I am also interested in space weather effects on middle atmosphere circulation.
I am a Co-I on the NERC funded DRAGON-WEX grant (led by colleagues at Bath University) which will investigate the role of gravity waves around 60S in driving atmospheric circulation in this region (https://www.bas.ac.uk/project/dragon-wex/)
I am on the science committee for the ANtarctic Gravity Wave Instrument Network (ANGWIN) which is a SCAR action group looking to study gravity waves across Antarctica using international collaborations (https://www.bas.ac.uk/project/angwin/)
I am joint PI (with Prof. Taylor of Utah State University) of two all-sky airglow imagers currently located at Rothera.
I am PI for 2 airglow spectrometers and a ship-borne airglow imager system.
These instruments all observe airglow perturbations caused by gravity waves at around 90km altitude. I also use radiosonde data, gathered routinely by our meteorologists, to study gravity wave activity in the lower stratosphere.
I am also a joint PI for a meteor radar located at King Edward Point, South Georgia. This radar measures wind speeds in the middle atmosphere and can be used to study atmospheric tides and gravity waves.
