ACTRIS-IT is closely monitoring air composition during COVID-10 lockdown.

Date: 30.03.2020

ACTRIS-Italy is collecting parallel measurements of atmospheric composition at different altitudes and urbanization contexts in Northern Italy.

According to first analyses, surface concentration of NO2 have decreased in north Italy of about 10% per week during the last four or five weeks4,5. The concentrations of another major air pollutant, the particulate matter (PM10 and PM2.5), have declined too but with large day-to-day variations: after two weeks of lockdown and large reductions in traffic activity in north Italy, PM10 levels above the threshold of 50 mg m-3 are still recorded in several cities of the Po Valley.

The main facility operative within ACTRIS in Northern Italy is “Monte Cimone – Po Valley observatory” (CMN-PV). It is a distributed infrastructure including the GAW and ICOS stations of Monte Cimone (http://www.isac.cnr.it/cimone/) in the northern Apennines, and the two stations of San Pietro Capofiume and Bologna in the south sector of the Po Valley. It is a unique observatory for providing parallel measurements of atmospheric composition at different altitudes and urbanization contexts in the same geographical area. Preliminary measurements at Monte Cimone (2165 m a. s. l.) show reduced submicron aerosol concentrations compared to 2019 (Fig. 1). If confirmed, a negative anomaly with respect to the climatology will proof that the abatement of anthropogenic emissions caused by the lockdown are affecting the composition of the background atmosphere in this region of the world.

At the low altitude sites of the observatory (Bologna and San Pietro Capofume), advanced aerosol measurements are set up during intensive observation periods. Currently, a state-of-the-art high-resolution aerosol time-of-flight mass spectrometer (HR-ToF-AMS) is being operated in Bologna (Fig. 2). The instrument provides real-time submicron aerosol chemical composition measurements providing unparalleled detail on the time-resolved PM source contributions including traffic, residential combustion and secondary formation. First observations during the lockdown show that the concentrations of several particulate anthropogenic pollutants – like ammonium nitrate – are still very dynamic in the Po Valley, with a large variability induced by meteorological factors. Accounting for such effects provides baseline knowledge for quantifying the impact of emission changes on PM concentration levels. Probing the complexity of the meteorological and chemical processes linking emissions to concentrations is one of the targets of ACTRIS.

International scientific networks and collaborations are of great importance for the empowerment of regional monitoring networks for priority scientific objectives. Further advanced aerosol observations, including multichannel aerosol size and mobility distributions measurements, are being set up in collaboration with the University of Modena, Helsinki and of Eastern Finland. 

The established scientific collaborations between CNR and other partners with the EU institutions responsible for satellite Earth observations (EUMETSAT, ASI) will enable to benchmark remote-sensed air quality parameters with the advanced in situ ground measurements carried out by ACTRIS for a more quantitative assessment of the impact of emissions on concentrations and exposure.

In these extraordinary times, scientific research must take a pro-active role to achieve quantitative information on the human impact on the environment, as such information will be key for governance in the upcoming years.

ACTRIS response to air quality observation at the time of SARS-CoV-2.

Date: 24.03.2020, Last update: 27.03.2020

 

Air quality has changed across Europe, and in particularly in Northern Italy, in conjunction with the lockdown implemented in many countries to fight against the outbreak of SARS-CoV-2.

Data from Copernicus Sentinel-5P satellite1 and from the Copernicus Atmosphere Monitoring Service (CAMS) reanalysis2 have revealed that nitrogen dioxide (NO2) emissions drastically diminished in the Po Valley as the lockdown halts most of the traffic and industrial activities. Additionally, reductions in particulate matter (PM10) concentrations and low variability have been observed in different regions of Europe.

 

ACTRIS supports rapid, high-quality data to observe atmospheric composition changes during global health crises.

Researches are interested in obtaining accurate and highly reliable data on air quality which can help understanding  if and how aerosol can be linked with the transport of SARS-CoV-2. 

ACTRIS is currently gathering atmospheric composition measurements from ACTRIS platforms across different areas in Europe which will directly impact the reliability of air quality studies by providing crucial information on aerosol and trace gases variables during the SARS-CoV-2 pandemics.

The Italian component of the distributed research infrastructure ACTRIS (ACTRIS-IT) is based on a number of different facilities distributed throughout the national territory including observational sites with multiparameter instrumentation, laboratories and experimental simulation chambers. ACTRIS-IT is collecting parallel measurements of atmospheric composition at different altitudes and urbanization contexts in the Po Valley.

ACTRIS will also prepare specific, user-friendly data sets of the atmospheric observations for various user groups when the lockdown situation is over for further detailed studies and analyse the environmental and societal impacts of the COVID-19 and the closing down of several sectors of society (e.g. transport, industry, services).

 

ACTRIS actively engages with the wider community of Research Infrastructures in Europe to support joint activities for SARS-CoV-2 research.

ACTRIS is collaborating with the European Strategy Forum on Research Infrastructures (ESFRI) and the Association of European-Level Research Infrastructures Facilities (ERF-AISBL)4 to create dedicated spaces favoring the uptake of services offered by RIs in support of scientists conducting research related to SARS-CoV-2.

ACTRIS is developing towards becoming an ERIC

ACTRIS is developing towards becoming a European Research Infrastructure Consortium (ERIC).

On 23rd of January 2019, the Interim ACTRIS Council (IAC) has mandated Finland to submit ACTRIS ERIC Step 1 documents to the European Commission.

ACTRIS ERIC provides the governance of ACTRIS. ACTRIS ERIC establishes and operates the research infrastructure and coordinates the strategic and financial development and eventual long-term operation of ACTRIS.

ACTRIS is an European Research Infrastructure for short-lived atmospheric constituents increasing the excellence in Earth system observation and research and providing information and knowledge for developing sustainable solutions to societal needs.

 

ACTRIS ERIC statutory seat will be hosted by Finland and the ACTRIS Head Office operated by Finland and Italy. 

For more information contact ACTRIS Office.

Finland to host ACTRIS ERIC Statutory seat

On 8th of June 2018, the Interim ACTRIS Council (IAC) approved the Finnish offer to host ACTRIS ERIC (European Research Infrastructure Consortium). Finland expressed its willingness to host the statutory seat for ACTRIS ERIC in 2015 in the proposal to ESFRI 2016 Roadmap. In May 2018 the Finnish Committee confirmed the commitment and the readiness to lead and coordinate the ACTRIS ERIC application process.

ACTRIS will be coordinated by the legal entity ACTRIS ERIC. The task of ACTRIS ERIC is to establish and operate a distributed research infrastructure, which shares high-quality datasets and provides services tailored for scientific and public usage in the area of atmospheric sciences. ACTRIS ERIC provides the governance of ACTRIS, and coordinates the strategic development in order to secure the long-term operation of ACTRIS.

The preparations for ACTRIS as a research infrastructure started back in 2014 and currently there are 18 European countries involved at ministry level. ACTRIS plans to be fully operational by 2025 and will offer its services for at least 20 years.
