SUMMARY:Steps towards understanding tropospheric composition variability -
  Dr Apostolos Voulgarakis (Imperial College)
DTSTART:20150209T141500Z

CONTACT:Dr Amanda Maycock
DESCRIPTION:The composition of the troposphere varies strongly both in spa
 ce and in time\, especially when considering short-lived constituents such
  as oxidants (e.g. hydroxyl radicals and ozone)\, ozone precursors (nitrog
 en oxides\, carbon monoxide etc)\, and aerosols. Several aspects of this v
 ariability are not well understood. In this talk\, previous and ongoing wo
 rk that explores such aspects is going to be discussed. The primary focus 
 will be on interannual variations of the constituents mentioned above. The
  role of possible drivers of variability is going to be discussed\, with a
 n emphasis on biomass burning\, meteorology\, and cloud-related effects. E
 xamples of how satellite information can be used in conjunction with globa
 l modelling to understand the variability of tropospheric constituents and
  their radiative forcing are going to be demonstrated.
