A high-resolution gridded inventory of coal mine methane emissions for India and Australia

Coal mines are globally an important source of methane and also one of the largest point sources of methane. We present a high resolution 0.1° × 0.1° bottom-up gridded emission inventory for methane emissions from coal mines in India and Australia, which are among the top five coal producing countries in 2018. The aim is to reduce the...

Modelling ultrafine particle number concentrations at address resolution in Denmark from 1979-2018 – Part 1: Regional and urban scale modelling and evaluation

The integrated model system DEHM/UBM/AirGIS, developed at Aarhus University, Department of Environmental Science, has been extended with the dynamic aerosol module M7 to account for particle number concentrations of particles with diameters below 1 μm in the atmosphere. The aim of this development is to quantify the spatial and temporal...

Global anthropogenic CO2emissions and uncertainties as a prior for Earth system modelling and data assimilation

The growth in anthropogenic carbon dioxide (CO2) emissions acts as a major climate change driver, which has widespread implications across society, influencing the scientific, political, and public sectors. For an increased understanding of the CO2 emission sources, patterns, and trends, a link between the emission inventories and observed CO2...

Satellite observations reveal extreme methane leakage from a natural gas well blowout

Methane emissions due to accidents in the oil and natural gas sector are very challenging tomonitor, and hence are seldomconsidered in emission inventories and reporting. One of the main reasons is the lack of measurements during such events. Here we report the detection of large methane emissions from a gas well blowout in Ohio during February...

Evaluating cloud properties in an ensemble of regional online coupled models against satellite observations

Online coupled meteorology-chemistry models permit the description of the aerosol-radiation (ARI) and aerosol-cloud interactions (ACIs). The aim of this work is to assess the representation of several cloud properties in regional-scale coupled models when simulating the climate-chemistry-cloud-radiation system. The evaluated simulations are...

Evaluation of the performance of four chemical transport models in predicting the aerosol chemical composition in Europe in 2005

Four regional chemistry transport models were applied to simulate the concentration and composition of particulate matter (PM) in Europe for 2005 with horizontal resolution 20 km. The modelled concentrations were compared with the measurements of PM chemical composition by the European Monitoring and Evaluation Programme (EMEP) monitoring...

Insights into the deterministic skill of air quality ensembles from the analysis of AQMEII data

Simulations from chemical weather models are subject to uncertainties in the input data (e.g. emission inventory, initial and boundary conditions) as well as those intrinsic to the model (e.g. physical parameterization, chemical mechanism). Multi-model ensembles can improve the forecast skill, provided that certain mathematical conditions are...

Identification and cross-checking of large point source SO2 emissions in Europe using OMI retrievals

European SO2 emissions from large points sources (LPS) were cross-checked with satellite S2 measurements from the Ozone Monitoring Instrument (OMI) on NASA's EOS-Aura satellite, averaged over a period of several years. Coordinates of the top-100 individual LPS in Europe were taken from the TNO point source database and corresponding OMI S2 plots...

Evolution of anthropogenic and biomass burning emissions of air pollutants at global and regional scales during the 1980-2010 period

Several different inventories of global and regional anthropogenic and biomass burning emissions are assessed for the 1980-2010 period. The species considered in this study are carbon monoxide, nitrogen oxides, sulfur dioxide and black carbon. The inventories considered include the ACCMIP historical emissions developed in support of the...

Abatement strategies to reduce air pollution from transport in Germany

Large scale exceedances of PM₁₀ and N0₂ ambient air limit values will continue in Germany despite the implementation of national and international policies. An integrated approach has therefore been developed to assess different cost-effective mitigation strategies for all source groups on a national level. On-road and ofT...

Development of an integrated approach for the assessment of abatement strategies of Particulate Matter concentrations in Germany = Entwicklung Eines Integrierten Ansatzes für die Bewertung von Strategien zur Verminderung der Feinstaubbelastung in Deutschland

According to projected and modelled ambient air concentrations, large scale exceedances of PM10 limit values in Germany will continue despite implementation of current national and international legislation. Identification of the causes of these (current and projected) exceedances is crucial to develop successful mitigation options. Furthermore,...
