Norwegian greenhouse gas monitoring

Updated 2016-06-16

Continuous measurements of greenhouse gases and particles to monitor changes in the atmosphere. The programme is operated by Norwegian Institute of Air Research (NILU) on behalf of Norwegian Environment Agency. The Zeppelin Observatory is a major contributor of data on a global as well as a regional scale.The programme is decribed in the link.

This is not a National Implementation Plan (NIP) project

Data availability

Are data archived or planned to be archived at an AMAP Thematic Data Centre?
Data availability and access

All Norwegian data, including metadata are public after their release through annual reporting in Norwegian Environment Agency reports.

Samples/specimens archived in specimen banks?

Methods & Procedures

Procedures and methodology used for, e.g., sampling and sample storage, sample pretreatment, extraction and analysis, including which laboratories are involved, references to methods employed, etc.

The measurement programme includes 25 long lived greenhouse gases (CFCs, HCFCs, HFCs, halons, hydrogenated hydrocarbons SF6, CO, N2O, CH4, CO2 aerosol optical depth (AOD). These observations are partly included in the national monitoring programme, and partly activities financed and performed on the initiative of NILU. Also measurements of aerosol number and size distribution, light attenuation ("black carbon") , light scattering are performed at the observatory. These measurements are under the responsibility of ITM, University of Stockholm.

QA/QC Information (what QA/QC procedures are implemented, laboratories involvment in QA/QC activities, model verification/validation routines, etc.)

The halocarbon measurements are in accordance with AGAGE QA/QC procedures, the reactive trace gases and aerosol measurements are in accordance with ACTRIS QA/QC. The Zeppelin Observatory are in progress of being ICOS labelled for the CO2, CH4, CO.

Additional Information

Is this a bi- AND multi-lateral project (i.e. a project involving cooperation between different countries)?
Other institutes involved in the project

Is this project reporting to other organizations/programmes?

UNFCCC (UNFCCC), Advanced Global Atmospheric Gases Experiment (AGAGE), Montreal Protocol (Montreal Protocol). Aerosol data are reported to ACTRIS and EMEP, Zeppelin is in the process of beeing ICOS class 1 site.
