“…Several studies have applied inverse modelling techniques to the optimisation of CO emissions using observations from surface networks (Petron et al, 2004) as well as observations from the MOPITT and IASI satellite instruments. Most of these studies using satellite data have concluded that the a priori anthropogenic emissions of CO might be underestimated as indicated in Fig.…”

Abstract. Ozone holds a certain fascination in atmospheric science. It is ubiquitous in the atmosphere, central to tropospheric oxidation chemistry, yet harmful to human and ecosystem health as well as being an important greenhouse gas. It is not emitted into the atmosphere but is a byproduct of the very oxidation chemistry it largely initiates. Much effort is focused on the reduction of surface levels of ozone owing to its health and vegetation impacts, but recent efforts to achieve reductions in exposure at a country scale have proved difficult to achieve owing to increases in background ozone at the zonal hemispheric scale. There is also a growing realisation that the role of ozone as a short-lived climate pollutant could be important in integrated air quality climate change mitigation. This review examines current understanding of the processes regulating tropospheric ozone at global to local scales from both measurements and models. It takes the view that knowledge across the scales is important for dealing with air quality and climate change in a synergistic manner. The review shows that there remain a number of clear challenges for ozone such as explaining surface trends, incorporating new chemical understanding, ozone-climate coupling, and a better assessment of impacts. There is a clear and present need to treat ozone across the range of scales, a transboundary issue, but with an emphasis on the hemispheric scales. New observational opportunities are offered both by satellites and small sensors that bridge the scales.

“…Duncan et al [68] showed a 25% uncertainty remains for fossil fuel CO despite rigorous and extensive bottom-up estimates. The inconsistency of source estimates from the previous inversion analyses shown in Figure 1 also indicates that the uncertainty of each source is at least 20% for anthropogenic, 50% for biomass burning, 100% for biogenic hydrocarbon oxidation, and 15% for CH4 oxidation [14,[16][17][18][19][20][21]. Previous studies also carefully started inversion analyses using weak constraints: 50% of a priori source strength estimates [20,21,68,69,75].…”

“…Carbon monoxide emissions from fossil fuel and biofuel use are taken from [17]. They derived CO source strengths from April 2000 to March 2001 using MOPITT (Measurement of the Pollution in the Troposphere) satellite observations and updated the inventory monthly for 15 regions.…”

“…Most previous CO source strength estimates have used only concentration information [14,[16][17][18][19][20][21][22][23]. Regardless of the origin of concentration data sets (satellite, aircraft, or surface measurement), there were discrepancies of up to 30% in total CO inventory estimates as well as large variations among the source types of 15%-100% ( Figure 1).…”

Most previous top-down global carbon monoxide (CO) budget estimates have used only concentration information and shown large differences in individual source estimates. Since CO from certain sources has a specific isotopic signature, coupling the concentration and isotope fraction information can provide a better constraint on CO source strength estimates. We simulate both CO concentration and its oxygen isotopologue C O implies that more accurate source strengths are estimated. Thus, we confirmed that the observation of CO isotopes provide further substantial information for estimating a global CO budget. OPEN ACCESSAtmosphere 2015, 6 548

Air Pollution Modeling and Its Application XIX

Air quality prediction plays an important role in the management of our environment. Computational power and efficiencies have advanced to the point where chemical transport models can predict pollution in an urban air shed with spatial resolution less than a kilometer, and cover the globe with a horizontal resolution of less than 50 km. Predicting air quality remains a challenge due to the complexity of the governing processes and the strong coupling across scales. While air quality prediction is closely aligned with weather prediction, there are important differences, including the role of pollution emissions and their associated large uncertainties. As more atmospheric chemical observations become available chemical data assimilation is expected to play an essential role in air quality forecasting. In this paper the current status of air quality forecasting is discussed and illustrated by comparison of predictions with observations. The future directions are also discussed, with an emphasis on data assimilation. Applications of the four dimensional variational method (4D-Var) and the ensemble Kalman filter (EnKF) approach are presented and discussed.
