| Summary: | We present an overview of the coordinated global numerical modelling
experiments performed during 2012–2016 by the Task Force on Hemispheric
Transport of Air Pollution (TF HTAP), the regional experiments by the Air
Quality Model Evaluation International Initiative (AQMEII) over Europe and
North America, and the Model Intercomparison Study for Asia (MICS-Asia). To
improve model estimates of the impacts of intercontinental transport of air
pollution on climate, ecosystems, and human health and to answer a set of
policy-relevant questions, these three initiatives performed emission
perturbation modelling experiments consistent across the global, hemispheric,
and continental/regional scales. In all three initiatives, model results are
extensively compared against monitoring data for a range of variables
(meteorological, trace gas concentrations, and aerosol mass and composition)
from different measurement platforms (ground measurements, vertical profiles,
airborne measurements) collected from a number of sources. Approximately 10
to 25 modelling groups have contributed to each initiative, and model results
have been managed centrally through three data hubs maintained by each
initiative. Given the organizational complexity of bringing together these
three initiatives to address a common set of policy-relevant questions, this
publication provides the motivation for the modelling activity, the rationale
for specific choices made in the model experiments, and an overview of the
organizational structures for both the modelling and the measurements used
and analysed in a number of modelling studies in this special issue. |
