Beregning av korrosjonsklasse fra miljøparametere i Fitjar. Lokasjon (59°56’11.5″N 5°19’58.4″Ø)

Grøntoft, Terje

Korrosjonsklasse ble beregnet på lokasjon (59°56'11.5"N 5°19'58.4"Ø) i Fitjar, Vestland, Norge, fra årsgjennomsnitt for miljøparametere etter ISO 9223 og ISO 12944-2. Det ble funnet at korrosjonsklassen med høy sannsynlighet er C3 og at dette i hovedsak er bestemt av våt-tiden på omtrent 4500 timer/år, som gjennomsnitt i perioden 2007-2022. Dette er godt innenfor grensene for C3 når saltavsetningen er < 60 mg Cl-/m2døgn og SO2 konsentrasjonen i luft < 30 µg/m3. Disse betingelsene synes med stor sannsynlighet oppfylt på lokasjonen i Fitjar som årsgjennomsnitt i normalår.

Tiltaksutredning for lokal luftkvalitet i Levanger. Del 1: Kartlegging.

Weydahl, Torleif; Teigland, Even Kristian

Tiltaksutredningen for lokal luftkvalitet i Levanger, del 1 Kartlegging, skal gjøre rede for forurensningssituasjonen og mulige tiltak for å redusere nivået av luftforurensning innenfor kravene i forurensningsforskriften. Tiltaksutredningen omfatter en kartlegging med utslipps- og spredningsberegninger for alle relevante kilder til PM10 og PM2,5 i 2017 og 2019. I tillegg er det utført målinger av disse komponentene gjennom hele 2021 ved en målestasjon (Kirkegata) i Levanger sentrum. Basert på resultatene fra kartleggingen, er det foreslått en handlingsplan med fire hovedpunkter som kan bidra til å redusere forurensningsnivåene i Levanger.

Status report of air quality in Europe for year 2020, using validated data

Targa, Jaume; Ripoll, Anna; Banyuls, Lorena; Ortiz, Alberto González; Soares, Joana

This report presents summarised information on the status of air quality in Europe in 2020, based on validated air quality monitoring data officially reported by the member and cooperating countries of the EEA. It aims at informing on the status of ambient air quality in Europe in 2019 and on the progress towards meeting the European air quality standards for the protection of health, as well as the new WHO air quality guidelines. The report also compares the air quality status in 2020 with the previous three years. The pollutants covered in this report are particulate matter (PM10 and PM2.5), O3, NO2, benzo(a)pyrene (BaP), SO2, CO, benzene and toxic metals (As, Cd, Ni, Pb). Measured concentrations above the European air quality standards for PM10, PM2.5, O3, NO2 were reported by 20, 6, 21, and 8 European countries for 2020, respectively. Exceedances of the air quality standards for BaP, SO2, CO, and benzene were measured in, respectively, 11, 19, 2, and 0 European countries in 2020. Exceedances of European standards for toxic metals were reported by 7 stations for As, 0 for PB, 1 for Cd and 2 for Ni.

Status report of air quality in Europe for year 2021, using validated and up-to-date data

Targa, Jaume; Ripoll, Anna; Banyuls, Lorena; Ortiz, Alberto González; Soares, Joana

This report presents summarised information on the status of air quality in Europe in 2021, based on Up-To-Date (i.e. prior to final quality control) and validated air quality monitoring data reported by the member and cooperating countries of the EEA. It aims at giving more timely and preliminary information on the status of ambient air quality in Europe in 2021 for five key air pollutants (PM10, PM2.5, O3, NO2 and SO2). The report also gives a preliminary assessment of the progress towards meeting the European air quality standards for the protection of health and the new World Health Organization air quality guidelines, and compares the air quality status in 2021 with the previous three years. The preliminary data reported for 2021 shows that more than 11% and 9% of the monitoring stations exceeded the EU standards for PM10 and O3, respectively. The WHO AQG for PM2.5, PM10, O3 and SO2 were exceeded by 94%, 66%, 92% and 4%, respectively. Exceedances of the NO2 limit value still occur in 8 reporting countries and WHO AQG still occur in 35 reporting countries.

Synergistic exploitation of the methane product from Sentinel-SP for applications in the Arctic (STEPS)

Stebel, Kerstin; Kylling, Arve; Schneider, Philipp; Ytre-Eide, Martin

The main goal of this feasibility study was to evaluate the potential of adding value to the Sentinel 5P TROPOMI methane product over Norway and the Arctic through the synergistic use of relevant observations from other Sentinel satellites and machine learning. We assessed the data availability of ESA operational and research-based WFMD XCH4 products over the Northern hemisphere, the Nordic countries and the Arctic/Northern latitudes. ESA’s XCH4 data have poor coverage over Norway. Seeing the two datasets as complementary, seems to be the most reasonable approach for utilization them. Furthermore, we investigated potential synergies between satellite products from different platforms. A random forest (RF) machine learning algorithm was implemented. It shows the importance of daytime land surface temperature (LST) as predictor variable for CH4. Our results indicate that the RF-model has a very good capability of filling small gaps in the data.

The Covid-19 pandemic and environmental stressors in Europe: synergies and interplays

Bartonova, Alena (eds.) Colette, Augustin; Zhang, Holly; Fons, Jaume; Liu, Hai-Ying; Brzezina, Jachym; Chantreux, Adrien; Couvidat, Florian; Guerreiro, Cristina; Guevara, Marc; Kuenen, Jeroen J.P.; Solberg, Sverre; Super, Ingrid; Szanto, Courtney; Tarrasón, Leonor; Thornton, Annie; Ortiz, Alberto González

This report provides an overview of the potential impacts of Covid-19 restrictions, in particular, focusing on review and assessment of Covid-19 impacts on air quality, for the year 2020. Complementary analyses address compliance with the National Emission reductions Commitments (NEC) Directive and noise. This expands the initial analysis of impacts of the pandemic-related restrictions on air quality based on data for the first months of 2020, presented in the EEA Air quality report for 2020. The results show a clear decline in NO2 short-term levels and annual average throughout Europe. Results for other pollutants are less uniform, and mostly do not show significant changes in annual average or other relevant metrics . The results regarding air quality are robust, obtained by a wealth of methods and consistent also with literature findings. The noise analysis shows a general decline in noise levels related to road traffic, though some areas show an increase. An analysis of policies and measures reported by Member States in 2021 for base year 2019 shows that additional measures related to emissions of NH3 are expected to be negatively impacted to the greatest extent by the Covid-19 related restrictions.
