“…They found consistent and significant negative trends mostly in areas of anthropogenic sources over Western Europe and isolated and scattered positive trends in Eastern Europe, which is in agreement with many other studies, such as for example, Schneider and van der A (2012). Castellanos and Boersma (2012) Curier et al (2014) studied trends in NO x emissions over Europe. Similarly to other studies they found significant negative trends of 5-6 % yr −1 in highly industrialized regions of Europe, with the strongest reductions in northern Spain and the Po Valley.…”

Abstract. Trends in tropospheric nitrogen dioxide (NO 2 ) columns over 66 large urban agglomerations worldwide have been computed using data from the SCanning Imaging Absorption spectroMeter for Atmospheric CHartographY (SCIAMACHY) instrument onboard the Envisat platform for the period August 2002 to March 2012. A seasonal model including a linear trend was fitted to the satellite-based time series over each site. The results indicate distinct spatial patterns in trends. While agglomerations in Europe, North America, and some locations in East Asia/Oceania show decreasing tropospheric NO 2 levels on the order of −5 % yr −1 , rapidly increasing levels of tropospheric NO 2 are found for agglomerations in large parts of Asia, Africa, and South America. The site with the most rapidly increasing absolute levels of tropospheric NO 2 was found to be Tianjin in China with a trend of 3.04(±0.47) × 10 15 molecules cm −2 yr −1 , whereas the site with the most rapidly increasing relative trend was Kabul in Afghanistan with 14.3(±2.2) % yr −1 . In total, 34 sites exhibited increasing trends of tropospheric NO 2 throughout the study period, 24 of which were found to be statistically significant. A total of 32 sites showed decreasing levels of tropospheric NO 2 during the study period, of which 20 sites did so at statistically significant magnitudes. Overall, going beyond the relatively small set of megacities investigated previously, this study provides the first consistent analysis of recent changes in tropospheric NO 2 levels over most large urban agglomerations worldwide, and indicates that changes in urban NO 2 levels are subject to substantial regional differences as well as influenced by economic and demographic factors.

“…Among other applications, this module was used to study the origin of particulate matter in the Netherlands , changing source receptor relations for energy scenarios in Europe (Hendriks et al, 2015) and particulate matter sources in Chinese cities and regions . Another application was to investigate the sensitivity of the OMI instrument to NO x emission sources in Europe Curier et al, 2014). The module was also recently used on a high-resolution application for the Netherlands to determine the influence of several source sectors (e.g.…”

Curriculum vitae of the LOTOS–EUROS (v2.0) chemistry transport model

et al. 2017

View full text Add to dashboard Cite

Abstract. The development and application of chemistry transport models has a long tradition. Within the Netherlands the LOTOS-EUROS model has been developed by a consortium of institutes, after combining its independently developed predecessors in 2005. Recently, version 2.0 of the model was released as an open-source version. This paper presents the curriculum vitae of the model system, describing the model's history, model philosophy, basic features and a validation with EMEP stations for the new benchmark year 2012, and presents cases with the model's most recent and key developments. By setting the model developments in context and providing an outlook for directions for further development, the paper goes beyond the common model description.With an origin in ozone and sulfur modelling for the models LOTOS and EUROS, the application areas were gradually extended with persistent organic pollutants, reactive nitrogen, and primary and secondary particulate matter. After the combination of the models to LOTOS-EUROS in 2005, the model was further developed to include new source parametrizations (e.g. road resuspension, desert dust, wildfires), applied for operational smog forecasts in the Netherlands and Europe, and has been used for emission scenarios, source apportionment, and long-term hindcast and climate change scenarios. LOTOS-EUROS has been a front-runner in data assimilation of ground-based and satellite observations and has participated in many model intercomparison studies. The model is no longer confined to applications over Europe but is also applied to other regions of the world, e.g. China. The increasing interaction with emission experts has also contributed to the improvement of the model's performance. The philosophy for model development has always been to use knowledge that is state of the art and proven, to keep a good balance in the level of detail of process description and accuracy of input and output, and to keep a good record on the effect of model changes using benchmarking and validation. The performance of v2.0 with respect to EMEP observations is good, with spatial correlations around 0.8 or higher for concentrations and wet deposition. Temporal correlations are around 0.5 or higher. Recent innovative applications include source apportionment and data assimilation, particle number modelling, and energy transition scenarios including corresponding land use changes as well as Saharan dust forecasting. Future developments would enable more flexibility with respect to model horizontal and vertical resolution and further detailing of model input data.Published by Copernicus Publications on behalf of the European Geosciences Union.

The version 3 OMI NO<sub>2</sub> standard product

Abstract. We describe the new version 3.0 NASA Ozone Monitoring Instrument (OMI) standard nitrogen dioxide (NO 2 ) products (SPv3). The products and documentation are publicly available from the NASA Goddard Earth Sciences Data and Information Services Center (https://disc. gsfc.nasa.gov/datasets/OMNO2_V003/summary/). The major improvements include (1) a new spectral fitting algorithm for NO 2 slant column density (SCD) retrieval and (2) higherresolution (1 • latitude and 1.25 • longitude) a priori NO 2 and temperature profiles from the Global Modeling Initiative (GMI) chemistry-transport model with yearly varying emissions to calculate air mass factors (AMFs) required to convert SCDs into vertical column densities (VCDs). The new SCDs are systematically lower (by ∼ 10-40 %) than previous, version 2, estimates. Most of this reduction in SCDs is propagated into stratospheric VCDs. Tropospheric NO 2 VCDs are also reduced over polluted areas, especially over western Europe, the eastern US, and eastern China. Initial evaluation over unpolluted areas shows that the new SPv3 products agree better with independent satellite-and ground-based Fourier transform infrared (FTIR) measurements. However, further evaluation of tropospheric VCDs is needed over polluted areas, where the increased spatial resolution and more refined AMF estimates may lead to better characterization of pollution hot spots.
