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 http://abc-is.jrc.ec.europa.eu/. 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 (www.europe-fluxdata.eu, fluxnet.ornl.gov, www.ingos-infrastructure.eu, 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
JRC - Ispra atmosphere - biosphere - climate integrated monitoring station : 2011 report( )

1 edition published in 2013 in English and held by 2 WorldCat member libraries worldwide

The Institute for Environment and Sustainability provide long-term observations of the atmosphere within international programs and research projects. These observations are performed from the research infrastructure named ABC-IS: Atmosphere – Biosphere – Climate Integrated monitoring station. Most measurements are performed at the JRC-Ispra site. Observations are also carried out from two other platforms: the forest station in San Rossore, and a ship cruising in the Western Mediterranean sea. This document reports about measurement programs, the equipment which is deployed, and the data quality assessment for each site. Our observations are presented, compared to each other, as well as to historical data obtained over the past 25 years at the Ispra site

Field evaluation of NanoEnvi microsensors for O3 monitoring( )

1 edition published in 2012 in English and held by 1 WorldCat member library worldwide

Previous studies have showed that microsensors can successfully measure ozone in ambient air for a limited period of time after on-site calibration by comparison to ultraviolet photometry. This method is generally more successful than the calibration in exposure chambers under controlled conditions because of the difference between laboratory and fields air matrixes. To expand this result, we carried out an experiment at two sampling sites. At the first site, the microsensors were calibrated during a few days. Subsequently, the calibrated microsensors were taken to another sampling site where the effectiveness of the calibration function of the first site was evaluated. The trend of the differences between UV photometry and microsensors were analyzed to evidence possible drift of the microsensors over time. The correlation of these differences with meteorological data was investigated to evidence possible interference and to propose new calibration methods

Evaluation of EDXRF for the determination of elements in PM10 filters( )

1 edition published in 2011 in English and held by 1 WorldCat member library worldwide

Energy Dispersive X-ray Fluorescence (EDXRF) was compared to Inductively Coupled Plasma Mass Spectrometer (ICP-MS) for the measurements of elements in particulate matter (PM10). Lead (Pb), arsenic (As), nickel (Ni) and cadmium (Cd)) and the ones included in the EMEP programme, namely copper, chromium and zinc were tested. Other elements such as magnesium, aluminium, silicon, sulphur, chloride, potassium, calcium, titanium, vanadium, iron, cobalt, manganese, bromide, strontium, molybdenum, tin and antimony, which are essential for source apportionment studies, were also tested. PM10 samples collected at different sites on several types of filter were analyzed using both EDXRF and ICP-MS. As the overall result of this study, EDXRF can be considered as an alternative method to ICP-MS for measurements of PM-bound elements, particularly on Teflon filters. The European legislative requirements of Pb could be met for whatever filters type. The European legislative requirements of Ni and As are likely be met, but, it is unknown for Cd. The EMEP requirements can be met for Cu and Zn, but not for Cr. EDXRF can also be used to measure elements for source apportionment purposes

Evaluation of lead (Pb), cadmium (Cd), arsenic (As), nickel (Ni) field comparison 2018 in Ispra (IT)( )

1 edition published in 2020 in English and held by 1 WorldCat member library worldwide

Within the quality assurance programme for air quality monitoring in Europe the JRC European Reference Laboratory for Air Pollution (ERLAP) organises Inter-Laboratory Comparison Exercises (ILC) for EU national air quality reference laboratories. An ILC for the determination of PM (particulate matter) mass concentration (PM10 and PM2.5) and metals (lead, cadmium, arsenic, nickel) was organised at European level in 2018. Such an ILC comprises the comparison between the PM samplers, the subsequent weighing procedures and further analysis of sampled filters used by the various participants. Samplers are therefore co-located for several days so that the number of test samples is large enough for statistical analyses. Thanks to the interest for this type of ILC and to the commitment from the AQUILA Network members, 27 Laboratories plus the European Reference Laboratory for Air Pollution deployed their instruments at a single place inside the premises of the Joint Research Centre in Ispra (Italy) during the same period of time (18 January - 14 March 2018). 28 samplers and one automatic analyser for PM10 and 23 samplers and one automatic analyser for PM2.5 collected ambient aerosol samples during a period of eight weeks. During this PM sampling campaign 13 laboratories agreed on performing subsequent metal analysis to verify the performance of their analytical method for the determination of metal concentration in ambient air. The samples for this analysis were collected from February 15th until the March 14th 2018. The scope of this inter-laboratory comparison was to assess the robustness of the measurement process and to determine the performance of the participants' procedures. For this ILC a simplified statistical analysis is reported. The assigned daily values were calculated as the robust average of all participants. The statistical evaluation included the reproducibility calculation, straggler and outlier identification. The exercise offered a unique opportunity to compare, between the participants, the whole analytical process from sampling to measurement step. All As. Cd, Ni, Pb concentrations were far below any limit or target value concentration. Despite the fact that the metals concentrations were very low the performance of all laboratories can be considered as excellent

Review of sensors for air quality monitoring( )

1 edition published in 2019 in English and held by 1 WorldCat member library worldwide

A growing number of companies started commercialising low-cost sensors (LCS) that are said to be able to monitor air pollution in outdoor air. One benefit of the use of LCS is the increased spatial coverage when monitoring air quality in cities and remote locations. Today, there are hundreds of LCSs commercially available on the market with a cost ranging from a few hundred to a few thousand euro. At the same time, the scientific literature currently reports independent information about the performance of sensor systems against reference measurements for about 110 sensor systems. In fact, the data quality of low-cost sensors is often questionable. It is affected by atmospheric conditions, pollutant concentration levels and therefore by the site location where the measurements are carried out. This report presents the collected results of quantitative studies of the performance of low-cost sensors against reference measurements. The information collected was an attempt to assess the following issues: · Agreement between sensor and reference measurements; · Availability of raw data, transparency of data treatment and possibility of a-posteriori calibration; · Capability to measure multiple pollutants; · Affordability of sensor systems taking into consideration the number of provided sensors. This information gathered in this report comes from research institutes having a LCS testing programme in place, e.g. the California Board - Air Quality Sensor Performance Evaluation Center (AQ-SPEC), the European Union Joint Research Centre (EU JRC) and the United States Environmental Protection Agency (US EPA). Other information was drawn from peer-reviewed journals that tested different types of sensors in research studies. Finally, this information has been linked with scripts able to perform a statistical analysis in the form of an electronic report. This work represents an important review to classify commercial sensors based on their agreement with reference systems. There are only a few available commercial sensor systems that are consistent with all issues mentioned above that show a good agreement with reference measurements (coefficient of determination, R², higher than 0.75 and slope of regression line within 1±0.5) and total price lower than 3 k€. The conclusion from this market analysis is that the only sensor system satisfying the requirements of multipollutant, availability of raw data, transparency of all applied data treatment, availability of evaluation of the performance of sensor system in literature with high coefficient of determination (>0.85) has been found to be the AirSensEUR v.2
