Abstract
Representation of atmospheric transport is a major source of error in the estimation of greenhouse gas sources and sinks by inverse modelling. Here we assess the impact
on trace gas mole fractions of the new physical parameterizations
recently implemented in the atmospheric global climate
model LMDz to improve vertical diffusion, mesoscale
mixing by thermal plumes in the planetary boundary layer
(PBL), and deep convection in the troposphere. At the same
time, the horizontal and vertical resolution of the model used
in the inverse system has been increased. The aim of this paper
is to evaluate the impact of these developments on the
representation of trace gas transport and chemistry, and to
anticipate the implications for inversions of greenhouse gas
emissions using such an updated model. © Author(s, 2015.
