Monitoring

High quality observations are essential to process studies, model validations, data assimilation and ensemble forecasting. The DMI has at its disposal a number of observatories and observation networks that are used to keep a number of atmospheric conditions under surveillance. These observations contribute greatly to the information, research and counselling for stratospheric ozone depletion and climate change provided by the DMI and other users and some of the observations are part of the network for the detection of atmospheric compostion change (NDACC). DMI also developed expertise in the past decade on quantitative assessment and optimization of observational networks through a series of EU-projects.

Measurements of ozone layer thickness above Denmark and Greenland and UV radiation levels for Denmark and the rest of the world are presented daily on dmi.dk (in Danish) and at NDACC.

DMI is actively involved in marine data exchange in the Baltic Sea and North Sea region through the Baltic and the North West European Shelf Operational Oceanographic System (BOOS and NOOS) network. DMI is the host of BOOS and NOOS websites and water level exchange network. 

Monitoring the Ozone Layer and the Solar UV radiation in Greenland

link: DANCEA: Projektlister (mst.dk)

Project aims: To continue the monitoring that was started in the early 90'es in order to fulfill the danish obligations to the "Vienna Convention for the Protection of the Ozone Layer". Part of the network for the Detection of Atmospheric Compostion Change (NDACC).

DMI’s role: To measure the Ozone Layer and the solar UV radiation at three locations in Greenland, at Thule/Pituffik, Scoresbysund/Ittoqqortoormiut and Sondre Stromfjord/Kangerlussuaq.

Funding: Danish Environmental Protection Agency (DANCEA), Ministry of Environment.

Period: Jan 1st, 2014 –  Dec 2025 (current contract)

Participants from DMI: , Nis Jepsen, Helge Jønch-Sørensen

AC SAF (EUMETSAT Satellite Application Facility on Atmospheric Composition Monitoring)

Link: https://acsaf.org

Project aims: The Satellite Application Facility on Atmospheric Composition Monitoring (AC SAF)  produces, archives, validates and disseminates ozone and atmospheric chemistry products, to support the services of the EUMETSAT Member States in weather forecasting, as well as monitoring of ozone depletion, air quality and surface UV radiation.

DMI’s role: DMI is responsible for the production, validation and dissemination of  the Near Real Time UV index products. 

Funding: EUMETSAT.

Period: Mar 2012 – Feb 2017.   CDOP-3 :  Mar. 2017 - Feb. 2022

Collaborators: FMI, DLR, KNMI, DWD, RMI, AUTH, BIRA-IASB, LATMOS, ULB
