Black carbon emitted by incomplete combustion of fossil fuels and biomass has a net warming effect in the atmosphere and reduces the albedo when deposited on ice and snow; accurate knowledge of past emissions is essential to quantify and model associated global climate forcing. Although bottom-up inventories provide historical Black Carbon emission estimates that are widely used in Earth System Models, they are poorly constrained by observations prior to the late 20th century. Here we use an objective inversion technique based on detailed atmospheric transport and deposition modeling to reconstruct 1850 to 2000 emissions from thirteen Northern Hemisphere ice-core records. We find substantial discrepancies between reconstructed Black Carbon emissions and existing bottom-up inventories which do not fully capture the complex spatial-temporal emission patterns. Our findings imply changes to existing historical Black Carbon radiative forcing estimates are necessary, with potential implications for observation-constrained climate sensitivity.

Review of the Assessment of Industrial Emissions with Mosses
På oppdrag fra Miljødirektoratet har NILU - Norsk institutt for luftforskning, gjort en litteraturstudie innenfor temaet
«Vurdering av industriutslipp ved bruk av mose». Hensikten er å framskaffe en oversikt over hva som er publisert av kunnskap om eventuelle sammenhenger mellom metallkonsentrasjoner målt i mose og utslippsmengder, luftkvalitet, opptak i andre
organismer og betydning for miljø og helse. Det er i tillegg etterspurt informasjon om hvorvidt andre land benytter
moseundersøkelse rundt industri og eventuelt hvordan disse resultatene blir brukt av myndigheter. Litteratursøket resulterte i 51 relevante publikasjoner hvor de fleste er fra perioden 2016-2019. Resultatene fra disse publikasjonene viser at mose er en god passiv prøvetaket for luftforurensinger og kan gi verdifull informasjon om kjemisk signatur og deposisjon av metaller. Det er ikke funnet noen studier som relaterer konsentrasjon i mose med luftkvalitet eller mengde utslipp fra utvalgte industrier. En enkelt studie forsøker å sette mosekonsentrasjoner i sammenheng med helseeffekter. En spørreundersøkelse blant deltakerland i ICP-Vegetation viser at resultater fra moseundersøkelser så langt ikke er benyttet av myndigheter i reguleringssammenheng eller lovgivning.

Review of methods that can be used in the assessment of atmospheric deposition
There are three main approaches for estimating the atmospheric deposition: 1) From measurements of air and precipitation chemistry combined with statistical interpolation, 2) Chemical transport models, 3) Combined observations and atmospheric model calculations. This report reviews these different approaches and come with some general recommendations on the different strategies and the way forward for Poland.
The report was made for the project "Strengthening of atmospheric deposition assessment in Poland based on Norwegian experience" under the program "Environment, Energy and Climate Change", financed by the European Economic Area Financial Mechanism 2014-2021".

Review of Interpreting Gaseous Pollution Data Regarding Heritage Objects
Pollutant gases pose a significant risk to some cultural heritage objects, and surveys have shown that the professionals involved consider themselves to lack knowledge to fully assess risk. Three approaches towards risk assessment, research results, standards and damage functions have been considered. An assessment tool has been developed, collating over 4000 research reports into a scheme for the impact on 22 materials of acetic and formic acids, nitrogen dioxide, ozone and reduced sulphur gases. The application of doses or concentrations has been considered, the impact of measurement time compared to annual exposure investigated and a simple tool derived.

Review of assessment of existing CAS/DAS, review of technical specification for CAS/DAS. NILU OR
NILU and GIOS, Poland, are implementing the project "Strengthening the air quality assessment system in Poland, based on Norwegian experience" as part of the programme "Improving Environmental Monitoring and Inspection" within the framework of the European Economic Area 2009-2014.
This report is a NILU review of two assessment reports covering Iséo and CSMS data management systems in use in Poland and the draft technical tender for purchasing a new data management system to replace the Iséo systems.
GIOS has, as part of the preparation for tendering, assessed the existing systems in the 16 VIEPs and compiled their findings in two reports. The VIEPs currently have 3 different systems. In the draft tender GIOS asks for a replacement of the existing XR systems from Iséo used in 8 VIEPs.
NILU has reviewed the documents provided by GIOS. However, due to the limited time available for this review, NILU has not carried out any technical testing of the current operational acquisition system, for verification of the documents claim's.
The assessment reports give a good overview of the DAS and CAS systems used in the VIEPs regarding both technical issues and user experiences. The information in the reports feeds into report no. 3 on tender specifications.

Review of ambient air quality monitoring programme in Poland. NILU OR
The Norwegian Institute for Air Research - NILU and the Chief Inspectorate of Environmental Protection - GIO¿ are implementing the project : 'Strengthening the air quality assessment system in Poland, based on Norwegian experience' as part of the programme ¿Improving Environmental Monitoring and Inspection¿ within the framework of the European Economic Area 2009-2014.
A part of this project is to review the existing ambient air quality monitoring programme in operation in Poland based upon the report prepared by GIOS: ¿Information on monitoring equipment used in Voivodeship networks within the National Environmental Monitoring and supplementary data providing grounds for network equipment analyses¿.
The NILU assessment confirms the needs described by GIOS to carry out an intensive monitoring of air quality, especially as regards PM10, PM2.5, benzo(a)pyrene and ozone. NILU advices GIOS to include the modelling results when evaluating the needs for expanding the network for ozone.NILU recommends to evaluate the needs for further stations in relation to securing the data capture rate as requested by the EU Directive.
In general, NILU advices GIOS towards having a more robust network that meets the Directive requirements regarding data coverage and ensures enough information for the WIOSs to do assessment and planning.

Reviderte beregninger av luftkvalitet ved Bjørnheimveien 26
NILU har blitt engasjert av Prem Partners II A/S for å vurdere utbredelse av luftsoner for dagens situasjon og en framtidig situasjon med foreslått boligblokk i Bjørnheimveien 26. Det er anvendt en Gaussisk spredningsmodell for linjekilder (Hiway-2). Når det tas hensyn til lokal topografi ved det aktuelle området, viser beregningene at den nye bygningen i hovedsak faller utenfor rød luftsone på bakkenivå, med unntak av det sørøstre hjørnet av bygningen som beregningene indikerer at ligger innenfor. Videre viser beregningene at skjermingseffekten for eksisterende bebyggelse av en ny bygning er marginal. Rapporten er en revisjon av NILU-rapport 15/2021.
