The European Commission Atmospheric Observatory : 2017 report( )

3 editions published between 2019 and 2021 in English and held by 3 WorldCat member libraries worldwide

Following the set-up of the greenhouse gas measurements in November 2016, the equipment for measuring short-lived pollutants and climate forcers was moved to the Atmospheric Observatory at the site of the historical EMEP-GAW site of the JRC in Ispra by July 1997. A comprehensive set of essential atmospheric variables have since then been measured at this single site to continue the assessment of the impact of European policies and international conventions on air pollution and climate forcing that started in 1985. The variables we measure at the Atmospheric Observatory in Ispra include greenhouse gas concentrations (CO2, CH4, N2O, SF6), radon (222Rn) activity concentration, short-lived gaseous and particulate pollutant (CO, SO2, NO, NO2, O3, PM2.5 and its main ionic and carbonaceous constituents) concentrations, atmospheric particle micro-physical characteristics (number concentration and size distribution) and optical properties (light scattering and absorption in-situ, light scattering and extinction vertical profiles remotely), eutrophying and acidifying species (SO42-, NO3-, NH4+) wet deposition. On-line measurements data are available in real time at Vegetation D atmosphere exchanges (CO2, O3, H2O and heat) are measured at our Mediterranean Forest Flux Station of San Rossore, backed up by meteorological and pedological measurements. All measurements are performed under international projects and programmes including ICOS (Integrated Carbon Observation System), ACTRIS (Aerosols, Clouds and Trace gases Research Infra-Structure), EMEP (co-operative Programme for Monitoring and Evaluation of the long range transmission of air pollutants in Europe) and GAW (Global Atmosphere Watch), each of which requires the use of standard methods and scales, and the participation in quality assurance activities. The JRC has a leading role in ACTRIS and EMEP regarding the quality assurance for carbonaceous aerosol measurements. Data obtained at Atmospheric Observatory are submitted to international open data bases (,,, ACTRIS Data Portal) and can be freely downloaded from these web sites. The data we produce are used in European wide assessments, for model inputs and validation, and for calibrating satellite airborne sensors. The European Commission Atmospheric Observatory 2017 report presents the data produced during the past year in the context of the previous years of measurements. All the essential in-situ and remote sensing measurements scheduled for 2017 were regularly performed across the year, except for short periods needed for moving, calibrating, and maintaining the equipment. Greenhouse gas (GHG) measurements have been performed at the JRC Ispra site since October 2007. Minimum values of CH4, N2O and SF6 measured in Ispra under clean air conditions are close to marine background values, while CO2 mixing ratios can even be lower than the Mace Head baseline due to the continental biospheric CO2 sink. Deviations from baseline concentrations provide information about regional and larger scale European greenhouse gas sources. From our daytime measurements, we derived increasing trends in CO2 (+0.5% yr-1) and CH4 (+0.4% yr-1) between 2008 and 2017, and in N2O (+0.3% yr-1) between 2001 and 2017. ICOS-compliant GHG measurements from the 100 m high tower of our new Atmospheric Observatory in Ispra started in December 2016. While CO concentrations slightly decreased (-2%) in 2017 compared to 2016, the concentrations of other short-lived pollutants monitored at the Atmospheric Observatory (NO2, O3, atmospheric particulate matter) have all increased by about 5 to 15%. In contrast, NH4+, NO3-, and SO42- wet deposition decreased (between -15 and -30%), but the number of acid rain events jumped from 3 in 2016 to 8 in 2017. These observations can be at least in part explained by the weather conditions, 2017 being exceptionally dry compared both to 2016 and to the decadal 1990-2000 average. In general, 2017 did not break the general decreasing trend in atmospheric pollution observed in Ispra since 1986. A noticeable exception regards ozone (O3), whose concentrations have remained relatively high in 2017. The indicators for health and ecosystem safeguard have deteriorated since 2012 (2014 excluded) compared to the 2000's. It would be worth studying the geographical extent of this tendency across Europe to understand its origin. The long time series in O3 indices and PM related variables (particle light scattering, particle number and wintertime mass concentrations, ...) suggest that a break in the decreasing trend in air pollution observed over the past 3 decades occurred around year 2014. This was particularly dramatic for O3, whose indicators for vegetation and human safeguard reached levels barely or never observed at the JRC-Ispra site in the past. Regarding particulate pollution, increased mass and number concentrations could have adverse effects on health. However, the increase in visible light scattering seen over the recent years is not accompanied by a similar increase in light absorption. This "lightening" of the atmospheric aerosol means that the negative radiative forcing (climate cooling) potential of the atmospheric particles encountered in our area has started to increase again. These observed changes in the long-term trends of particulate and O3 pollution would of course need to be confirmed over several more years and at other observatories to have a wider scientific and policy-relevant significance. The atmosphere D vegetation exchange measurements at our Mediterranean forest flux station of San Rossore show that the pine tree forest is a net sink for CO2 (510 gC/m² absorbed in 2017). The sequence of alternate wet and dry years since 2013 (when the measurement site was moved 600 m inland) allows us to observe that the total annual precipitation amount is not a key factor for determining the annual carbon sequestration by this Mediterranean
Particulate matter and health in 2020 are we on the right track? : policy advice and research directions : COST Action 633( Book )

1 edition published in 2008 in English and held by 2 WorldCat member libraries worldwide

The revised EU air quality directive is now on track after numerous legislative and implementation efforts during the last few years. During the revision and discussion of this directive, several important issues especially related to particulate matter (PM) were taken up within the Clean Air for Europe (CAFE) Programme. Not all issues could be tackled in the revision process due to lack of scientific data. There are still major uncertainties and serious gaps in the present scientific knowledge that need handling by the next evaluation of the air quality directive in 2013. The changing PM pollution in Europe leads to further information needs by stakeholders, policy-makers and decision-makers. Much more emphasis should be put on the role of PM in health impact and climate change. It is widely accepted that PM is an indicator for a complex mixture of air pollutants and that PM is highly correlated to many gaseous pollution components. Yet, for targeted abatement strategies, new information is needed on the most toxic emissions and conditions. Given that PM includes harmless as well as harmful material, indicators that are better linked with biological effects were discussed for their additional use in standard setting. The COST action 633 brought together experts in the field of particle measurements, transformation of atmospheric aerosols, exposure, epidemiology, toxicology and modeling of aerosol sources, atmospheric processing, and other fields and provided a genuinely interdisciplinary platform to formulate questions, discuss possible answers and identify research that needs to be performed in the near future and beyond. In a two-day meeting (Brussels, March 13 - 14, 2008) COST action 633 members gathered information and provided guidance for dealing with current heterogeneities and future changes in Europe-wide PM levels and characteristics, as well as the health implications due to air pollution and climate change mitigation policies.

Long-term trends in black carbon from biomass and fossil fuel combustion detected at the JRC atmospheric observatory in Ispra( Book )

1 edition published in 2018 in English and held by 1 WorldCat member library worldwide

The concentrations of equivalent black carbon deriving from biomass burning [eBC]bb and fossil fuel combustion [eBC]ff have been estimated from measurements of aerosol light attenuation at several wavelengths (from infrared to ultraviolet) performed at the atmospheric observatory of the Joint Research Centre located in Ispra (Northern Italy). The data show repeated seasonal cycles from 2004 to 2016, which suggests that winter time wood burning for domestic heating is the main biomass burning activity in this area. The [eBC]bb/[eBC]ff ratio has increased on average by +5%/yr over the 2007 – 2016 period. We compared these measurement-derived data with CO2 emissions estimated from EDGAR relative to biomass burning for domestic heating and fossil fuel combustion for transport (Diesel) and residential heating (coal + oil) in the 0.4°x0.4° area centred on Ispra. The data shows an increase in CO2 emissions from biomass burning compared to fossil fuel combustion from 2004 to 2008, and a rather constant ratio since then. There is no obvious correlation between the concentrations of [eBC] and the statistics on CO2 emissions from biofuel and fossil fuel combustion over the studied period. The impact of the economic crisis of 2009 on the use of biofuels for domestic heating cannot be rigorously demonstrated, neither from the measurement data nor from the emission inventory
Literature review for ODS (Ozone Depleting Substances) measurements methods and data( )

1 edition published in 2015 in English and held by 1 WorldCat member library worldwide

Stratospheric ozone absorbs most of the sun's harmful UV radiation. The increased use of human-produced gases such as chlorofluorocarbons (CFCs) has led to a magnified springtime depletion of the protective ozone layer at both Earth's poles, especially over Antarctica, a phenomenon well known as the ozone hole. The Montreal protocol [1] deals with substances that deplete the ozone layer (ODS) and how to reduce them (Montreal protocol, 1987 and amendments/adjustments). It covers substances with a high ozone depleting potential, CFCs and the 1st generation of CFC replacements (HCFCs). The success of the implementation of the Montreal protocol and amendments has to be demonstrated by the parties (including EU and its Member States [2]), and supported by high quality atmospheric measurements of relevant compounds.^Several atmospheric data-sets are available from open-access international data bases, including 7 stations across Europe: (1) Zeppelin, Ny-Ålesund, Norway, (2) Summit, Greenland, Denmark, (3) Mace Head, Ireland, (4) Tacolneston, UK, (5) Jungfraujoch, Switzerland, (6) Monte Cimone, Italy, and (7) Lampedusa (LMP), Italy, but data quality may in some cases be unknown or questionable. High-quality long-term ambient air data are mainly coming from the AGAGE Network ( [3]) and NOAA (National Oceanic and Atmospheric Administration). Ref. [3] comprising also European stations from e.g. (I) Ireland (first Agrigole (1978-1983), then Mace Head (from 1987 to present), (II) Switzerland (Jungfraujoch), from 2000 to present, (III) Norway (Ny Ålesund), from 2000 to present, and (IV) Italy (Monte Cimone) from 2002 to present.^The trends in ODS concentrations measured in-situ at ground level in Europe are consistent and, similar to the trends observed in the rest of the world (see ref. [4] containing in-situ ground level measurements, flask sampling and satellite observations), especially the downwards trend of CFCs, indicating the success of the Montreal Protocol, in limiting the atmospheric abundances of ODSs [4]. The UNEP/WMO Scientific Assessment of Ozone Depletion from 2014 states [4]: "The success of the Montreal Protocol in limiting the atmospheric abundances of ODSs is now well documented". This is confirmed by the AGAGE measurement network [3]: "International compliance with the Montreal Protocol is so far resulting in CFC and chlorocarbons abundances comparable to the target level so the Protocol is working". In contrast, it is of concern that the concentrations of HCFCs and N2O, where the latter one being currently the single most important gas that depletes stratospheric ozone (see e.g.^ref. Ravishankara et al., 2009 [15], and discussions in this report), are still increasing
