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.
Jerico (Link: www.jerico-fp7.eu)
Project aims: The project is aiming at providing a reliable valuation to the existing monitoring and observational systems for the European seas. The project is also purposed to form scientific guidance to optimize the existing monitoring and observational systems and to design additional new systems.
DMI’s role: DMI’s role: DMI is responsible for the Baltic Sea. We use data assimilation to evaluate how much the observational systems of T-S profiles and SST can improve the model products. We also evaluate how the new observational system of gliders should be applied in the Baltic Sea.
Monitoring the Ozone Layer and the Solar UV radiation in Greenland (link: danish (external))
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.
Project aims: The Satellite Application Facility on Ozone and Atmospheric Chemistry Monitoring (O3M 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 (uv-saf.dmi.dk).
Project aims: The polar portal communicates Arctic research and monitoring by Danish researchers to the public. Daily updated products on ice sheet, sea ice, permafrost and weather give easy and fast access to the newest knowledge.
DMI’s role: DMI contributes as project coordinator and with products on the Greenland Ice Sheet surface mass balance, the sea ice and Greenland permafrost. The technical development and hosting of the portal is done at DMI.
