Remote Sensing and Satellite Applications

Utilising specialist expertise from the EUMETSAT member states, Satellite Application Facilities (SAFs) are dedicated centres of excellence for processing satellite data and forming an integral part of the distributed EUMETSAT Application Ground Segment.

The eight EUMETSAT SAF's provide operational data and software products, each one for a dedicated user community and application area. DMI’s major involvements are OSISAF (Ocean and Sea Ice), ROMSAF (Radio Occultation Meteorology) and O3MSAF (Ozone and Atmospheric Chemistry Monitoring).

DMI’s remote sensing research covers atmosphere, ocean and cryosphere applications with focus on radar image processing, radio occultation, ozone and UV-radiation, SST, sea ice, iceberg, ice surface temperature and ice drift.

Defrost (Link:

Project aims: The aim of DEFROST (Impact of a changing cryosphere - Depicting ecosystem-climate feedbacks from permafrost, snow and ice) is to understand how climate change induced changes in the cryosphere influence the ecosystem/geosphere processes which directly affect climate. We will focus on key terrestrial, lacustrine and marine cryospheric components that have the potential for giving rise to substantial changes in climate feedback mechanisms both in terms of surface-atmosphere energy exchange and exchanges of greenhouse gases. DEFROST seeks to bridge existing gaps between climate modeling, cryospheric science, and Arctic ecosystem science.

DMI’s role: Improved parameterisation of permafrost, snow and ice related processes is being incorporated in the existing Regional Climate Models RCA (Sweden), HIRHAM (Denmark) and later in HARMONIE (International). The impact on changes in regional cryospheric/climate scenarios is investigated, beneficial also to the DEFROST user community and in terms of impacts and adaptation, by a provision of more elaborated regional scenarios. A novel element is the implementation of a sub-sea permafrost model in the HIRHAM-HYCOM coupled system for the Arctic based on the GIPL permafrost model develop in UAF in Alaska

eSurge (Link:

Project aims: To increase the use of satellite observations for storm surge applications. The project is assessing ocean model nowcasting and forecasting skills for storm surges in a test area (the North Sea and Baltic Sea) by combining a number of real time data sets, such as altimeter data and tide gauge data, with ocean forecast models to provide best estimates using data-assimilation techniques and best forecasts. 

DMI’s role: DMI has developed a new method of blending sea level observations from altimetry and tide gauges. This combines the high temporal resolution and real-time availability of tide gauges with the spatial cover of satellite altimetry, providing a nowcast of sea level based on observations. This product is then assimilated into DMI's ocean model covering the North Sea and the Baltic Sea. The model nowcast and forecast skills of the assimilated runs are compared to the non-assimilated runs. The impact of the assimilation will be assessed and disseminated in a report.

Project aims: GMES-PURE project defines and implements a transparent process for user involvement in the definition of long-term requirements for the Copernicus Marine and Atmosphere Services. The process covers the definition of user requirements, but also the derivation of service specifications, service data requirements and technical requirements on the observation infrastructure.

The project is based on a user-driven method, which consists of two main features:

1. continuous and broad user involvement, and

2. consensus seeking at all stages.

The process was successfully applied by EUMETSAT to its future satellite programmes, and an extension is sought to address the additional complexity of the Copernicus Marine and Atmospheric user communities.

The project will further develop the results of the previously organized EC user consultation meetings for the GMES M&A Services (GMES Implementation Groups, etc.). In particular, these results will be further consolidated through specific user workshops and domain expert reviews, for the EC final approval involving the GMES User Forum.

The project is led by EUMETSAT, providing project coordination and the process for requirements engineering from the identification of needs to the requirement validation.

DMI’s role: 
DMI works on the service gap analysis and service data specification. In the service gap analysis, DMI will compare the user requirement documents for Copernicus Marine Service and MyOcean2 Service catalogue, to identify gaps in mid- and long-term on parameters, resolution, temporal and spatial scales and quality etc. Based on gap analysis, more detailed service data requirements will be specified and documented.     

Funding: GMES-PURE is a FP7 project with about 2 million euro funding from EC.

S3vt-fa (Link:

Project aims: In situ Sea Surface Temperature measurements are very scarce at high latitude where satellite SST retrievals are particularly challenging. This project will provide detailed SST cal/val results for high latitudes during the Sentinel-3/SLSTR cal/val phase. This will be achieved through development and exploitation of a dedicated Sentinel-3/SLSTR MatchUp DB.

DMI’s role: 
Provide collocated Thermal-InfraRed radiometer data from the DMI-ISAR radiometer instrument operating on a Royal Arctic Lines vessel between Denmark and Greenland. The matched-Up DMI-ISAR and S3/SLSTR SST measurements will subsequently be exploited. The cal/val results will hereafter constitute a reference SLSTR matchup data set for high latitude SST due to the unique quality of the DMI-ISAR measurements.
