PRTRval: a software tool for the validation of E-PRTR emissions data

International Journal of Environment and Pollution (2014)

M. Dios Marta Morán Fabio Carrera Cesar Pombo J.A. Souto

The European pollutant release and transfer register (E-PRTR) is the Europe-wide emissions register that provides accessible environmental information about industrial facilities. Reporting of E-PRTR data to the European Commission requires that the member states assess the quality of their data. The errors and omissions in these data should be detected during the review process and corrected, claiming accurate and additional information to the industrial sources. In order to validate E-PRTR data, PRTRval software tool was developed and applied to the Galician industrial facilities. It provides a systematic procedure for the validation of emissions, based on a bottom-up approach to obtain a reference inventory that combines both standard and specific emission factors, and the activity factors yearly reported. The application of this validation procedure to the air pollutants 2010 E-PRTR dataset in Galicia shows that 54% of the emissions need correction or complementary information. The lack of information represented 24% of the errors.

An evaluation of road traffic emissions around Galician cities

WIT transactions on ecology and the environment (2010)

M. Dios Mark S. Castro J.A. Souto Juan J. Giner‐Casares

Road transport emissions have straightforward effects on air quality requirements, at local, regional and even global scales.Nowadays, almost all of motor vehicles use fossil fuels that, within their use, produce emissions of a same range of pollutants, although the amount and ratio are different according to the fuel, type of vehicle and combustion conditions.This fact is especially important in saturated roads, because vehicles caught in traffic jams are at the most polluting scenario, in comparison with regular use of a vehicle.Due to the importance of these emissions and trying to enforce legal specifications, technological improvements are installed on vehicles, which allow one to reduce emissions, as well as fuel consumption.These aspects are thought as the main issue in sustainable development in road transport around cities.The main aim of this work is to calculate and analyze contributions of the Atlantic Highway within Galicia, NW of Spain, to the road traffic pollution in the cities connected by it.The highway considered, covers more than 220 km from the NW to the SW of the region, and connects several major cities in Galicia.A standard methodology for estimation of road traffic was applied, based on EMEP/CORINAIR (Emission Inventory Guidebook 2007 Technical Report No. 16/2007.European Environment Agency EEA, 2007).To guarantee consistence and comparability of the results obtained, COPERT 4 (Computer Programme to Calculate Emissions from Road Traffic) was chosen.The pollutants considered were CO, NO x , NMVOC, SO x , NH 3 , GHG and particles, and the reference year is 2006.To assess the importance of highway emissions, it was necessary to calculate emissions from regular traffic in neighbouring areas.For comparison purposes, the present work focus on EMEP grid cells crossed by the highway.Cells are (49,14), (49,15), (49,16), (49,17), (50,13) and (50,14).Evaluation of EMEP cells www.witpress.com,

Evaluation of the E-PRTR emissions inventory: The Galician case

WIT transactions on ecology and the environment (2012)

M. Dios Marta Morán Fabio Carrera J.A. Souto Juan J. Giner‐Casares

Since 2008, E-PRTR is the European Emissions and Transfer Register of Pollutants, which was set to accomplish the UNECE Aarhus Convention about the information, public participation in decisions and access to the judgement in environmental issues.This pollutants emissions inventory follows a methodology based in the imperative declaration of emissions into the atmosphere and to water by the potential sources, included in the Directive 96/61/CE.As a consequence, the accuracy of this inventory depends on the information declared by the sources.In this work, a systematic methodology to validate the declared emissions was designed and applied to the Galician region.This methodology is based in a data structure of plant/activity-process-sourcepollutant, that is, a flowsheeting analysis of every plant was developed in order to associate each process to each source (i.e.chimney) at the same plant; with this approach, estimation of the pollutants emissions from every source is obtained by the calculation of emissions by process, based in different emissions factors.Of course, complementary data from the processes (i.e.fuel consumption, energy production, ...) is required.Results of the E-PRTR for 2008 and 2010 years at Galicia show significant differences between the emissions distribution by sector, depending on the pollutant; this can be explained by changes in the processes technologies and performance.About the validation, in a first stage less than 50% of the sources provided acceptable emissions with the complementary information for validation; some of them complete this information upon request.

H14-187 AIR QUALITY SIMULATIONS FOR NORTH AMERICA WITHIN AQMEII INITIATIVE

Joana Ferreira Ángel Rodríguez A. Monteiro Ana Isabel Miranda M. Dios

In the scope of the Air Quality Model Evaluation International Initiative (AQMEII), the air quality modelling system MM5- CAMx was applied to the North American (NA) domain for calendar year 2006. The simulation domain was defined according to the spatial resolution of the emission databases provided and the common grid required by AQMEII for ensemble analysis. A Lambert Conformal Projection grid of around 5500 km by 3580 km with 24x24 km 2 horizontal resolution was defined. Meteorological inputs were developed by the application of the meteorological model MM5, run for the whole year of 2006. A spatial and temporal analysis of results based on the 2D surface fields and time series for regional monitoring stations was performed for the main gaseous pollutants. A detailed statistical analysis and evaluation against observations was carried out, considering three different sub-domains over North America, in order to comprehend the differences between the East, West and Central part. Results have shown a good agreement between observed and modelled concentrations of O3 (especially regarding peaks) and NO2 and a weaker performance of the air quality model for CO and SO2. However, the model tends to underestimate O3 and overestimate NO2 and CO at night as a consequence of meteorology (weak vertical mixing due to underestimation of the Planetary Boundary Layer (PBL) height). This work intends to be a valuable contribution to the overall AQMEII exercise since it aims to evaluate the performance of individual models to be used in the ensemble approach for the areas of interest.

A mixed top-down and bottom-up methodology in spatial segregation of emissions based on GIS tools

WIT transactions on ecology and the environment (2012)

M. Dios J.A. Souto Juan J. Giner‐Casares N. Gallego A. Sáez

Gridded chemical transport models are often used for the assessment of air quality.For European continental scale the EMEP emissions inventory with a low 50x50 km 2 resolution is yearly available.However, current air quality models are usually applied with higher spatial resolution, in order to obtain representative results, especially in regional domains; therefore, a simple topdown approach based in the spatial interpolation of EMEP emissions is not appropriate.On the other hand, a bottom-up approach requires a huge amount of data to estimate the emissions source-by-source, which are not always justified for all the sources.The aim of this work is the development and application of a mixed top-down and bottom-up methodology for high resolution emissions inventories, based on EMEP emission data and other emissions data source (PRTR, UNFCCC and LRTAP).The emissions of the main industrial and road traffic sources (>50000 inhabitants cities, motorways) were obtained by a bottom-up approach, with industrial emissions considered from point sources.Other emissions from sparse sources are estimated following a top-down approach, based on the EMEP inventory, following a spatial segregation methodology which considers different geographical parameters, which are dependent on the source type.Data processing was performed using ArcMap GIS, following the CORINAIR structure [3].Therefore, results are easily updatable and they can be ,

Air pollutants emissions from cattle in Galicia, Spain

WIT transactions on ecology and the environment (2014)

Marta Morán D. J. González M. Dios

Cattle production has a significant contribution to the total GHGs emissions, particularly, CH 4 and N 2 O. Also, other air pollutants, as NH 3 and NMVOC, are emitted.As a European region with significant dairy and beef farms, Galicia (NW of Spain) is suitable to assess the contribution of cattle production to the regional livestock air pollutants emissions (namely, EMEP S10 in SNAP classification), considering up to date activity data.Therefore, the objective of this study is to update the annual emissions by dairy and beef cattle in Galicia, according to the different bottom-up methodologies: IPCC (Tier 1 and Tier 2) and EMEP/CORINAIR.This inventory is compared to both EMEP and E-PRTR emissions inventories: NH 3 cattle emissions are around half of EMEP S10, taking into account that EMEP S10 also includes other agriculture sources.NMVOCs cattle emissions are strongly higher than EMEP S10 emissions; moreover, there is no agreement in this region between S10 EMEP emissions and cattle farms geographical distributions.Besides E-PRTR does not include cattle farms emissions, CH 4 and NH 3 cattle emissions are 900 and 8 times higher than total current E-PRTR declared emissions at the same region: to add cattle farms in E-PRTR activities is highly recommended.

PRESAXIO regional air quality modelling system: validation and applications

International Journal of Environment and Pollution (2014)

J.A. Souto Santiago Saavedra Ángel Rodríguez M. Dios Javier López

Different operational air quality forecasts (ESSEM Cost Action 0602) are currently available in Europe. However, most of them are not suitable for regional application and, also, their coarse outputs do not fit well with air quality management needs. In this work, PRESAXIO regional air quality modelling system is validated and applied over Galicia (NW of Spain), including WRF and CHIMERE models. WRF validation is done by comparison with surface meteorological measurements; CHIMERE validation applies DELTA tool with AirBase data. PRESAXIO applications include an operational air quality forecast, design of a regional air quality monitoring network, and impact assessment of EMEP emissions changes in regional O 3 peaks.
