Research Interests:

  • The impact of atmospheric aerosol on clouds and climate.
  • Satellite estimates of aerosol radiative properties.
  • Radiative forcing of the climate system.

Research Projects:

  • Copernicus Atmosphere Monitoring Service (CAMS) : I am part of the CAMS74 team producing quantitative estimates of radiative forcing (RF) with respect to pre-industrial times (PI) using PI concentrations provided in the Fifth Assessment Report (AR5) of the Intergovernmental Panel on Climate Change (IPCC) from year 1750. The production chain being developed will use a CAMS global reanalysis dataset which will include data assimilated from recent satellite launches such as Sentinel-3 in order to produce improved RF estimates. CAMS consolidates previous research such as MACC and so the CAMS production chain is being prototyped using MACC reanalysis data.
  • South American Biomass Burning Analysis (SAMBBA) : The intentional burning of rainforest in the Amazon region produces dense clouds of smoke particles (also called biomass burning aerosols). These aerosols can affect local visibility and vegetation, but can also affect the passage of the sun's radiation through the atmosphere and the reflectiveness of clouds, which can ultimately affect global climate. In particular, particles that contain a lot of black carbon can burn off clouds, although the mechanism by which this occurs is poorly understood. I am investigating these effects using data collected by an airborne measurement campaign during 2012 and a large eddy simulation model.
