ABC4CDE: Assuring Best practiCes for Climate model Data Evaluation

Project aims: There are four core requirements for climate data provision: integrity, transparency, humility (in the sense of not presenting information as more than it is, nor less than it is), and collaboration; A well-designed framework for metadata and data structure helps approaching these goals. Data should be transparently obtainable and visible and the degree of quality indicated. Thus, the evaluation and quality control (EQC) framework aiming to fulfill this goal is essential for both the scientific and public audience. ABC4CDE targets assessments of user requirements, science and gaps in climate model data delivery concerning CMIP and Euro-CORDEX data. It focuses strongly on user requirements, data inventory and scientific assessment and gap analysis to formulate user-friendly and fit-for-purpose indicators, tools and services to be recommended for the C3S EQC framework.

DMI’s role: DMI will contribute to all aspects of the project. The main efforts are within the tasks associated with the scientific assessment and gap analysis. Here a particular focus is on defining basic tests of the suitability of impacts methods and models, a review of different approaches will be performed and emerging commonalities and recommendations will be extracted as an integral part of the EQC.

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.

EUCLEIA: European climate and weather events: Interpretation and attribution (link: english (external)

Project aims: Climate change is expected to impact extreme weather in Europe. There is therefore a clear need to adapt effectively to climate change, particularly in Europe, where recent heatwaves, floods and droughts have demonstrated the vulnerability of European citizens to extreme weather. However, scientifically robust information about the extent to which recent extreme weather can be linked to climate variability and change is often lacking.  EUCLEIA will provide well verified assessments of the extent to which such weather-related risks have changed due to human influences on climate and identify those types of weather events where the science is still too uncertain to make a robust assessment of attributable risk.

DMI’s role: Identify key-processes related to  sea-ice extent and the stratospheric vortex driving extreme events in particular cold spells.

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.

HydroCast – Hydrological Forecasting and Data Assimilation: (Link: english (external))

Project aims: HydroCast is a joint research project undertaken by a project team of fifteen research scientists, three PhD students and three end-users across ten institutions. In the HydroCast project new forecasting and data assimilation tools are developed and tested that combine different on-line data sources with meteorological and hydrological modelling for provision of probabilistic hydrological forecasts, covering short-range, medium-range and seasonal forecasting.  The tools are tested on three test cases but they will be generic and applicable in a wide range of cases. 

DMI’s role: 
DMI is involved  in two work packages  and  a test study.  In the first work package a quantitative precipitation forecast  system that combines weather radar and high-resolution short-range NWP modelling is  developed. Assimilation of weather radar is based on a nudging scheme that is implemented in the NWP model. The project will develop more effective quality control algorithms for state-of-the-art dual polarisation radars. In particular, major improvement is expected in identifying and removing false echoes in the weather radar data.  In the second work package DMI contributes to probabilistic precipitation forecasts using DMI’s atmospheric ensemble prediction system for precipitation.  DMI’s forecasts are used in a test study for an area around the new Silkeborg highway.

ice2ice (Link: coming up. See introduction video)

Project aims: ice2ice is the first concerted effort to the tackle question of the cause and future implications of past abrupt climate change in Greenland, the main hypothesis being that the Arctic and sub-Arctic sea ice cover excerts important controls on past and future Greenland temperature and ice sheet variations. In ice2ice this will be done by:

  • describing the nature, timing and wxtent of abrupt events across climate archives,
  • resolving mechanisms behind the sudden demise of sea ice cover,
  • identifying the risk that the ongoing rapid diminution of Arctic sea ice cover could give abrupt GIS changes in the future,
  • determining the impacts of such changes for the GIS and Arctic and global climate.

DMI's role: To further develop and apply global and regional Earth system models to be able to conduct experiments addressing the central question of the project. This involves, high resolution atmosphere modeling, a coupled high resolution regional climate model for the Arctic and using the global EC-Earth model. In most cases with an interactive ice sheet model (PISM) being part of the system. 3 PhD positions will form a central contribution to the project, but substantial funding is allocated to permanent staff at DMI.

MESO (MEteorological uncertainty of ShOrt-range dispersion)

Project aims: As shown by the recently completed NKS-B projects MUD and FAUNA, the influence of meteorological uncertainties on long-range atmospheric dispersion calculations can be large, e.g. up to an order of magnitude depending on the weather situation, with significant implications for nuclear emergency preparedness and decision making. The question that the MESO project is going to answer is to what extent this also applies to short-range (mesoscale) dispersion models employed for nuclear emergency preparedness up to about two hundred kilometres from the source.

The assessment of such uncertainties is facilitated by recent developments in numerical weather prediction (NWP) modelling through the use of ensemble methodology. The computer resource demanding procedures are now being, or are planned to be, implemented at a number of national weather services. This development enables operational quantitative calculation of uncertainties of the concentration and deposition patterns from accidental releases of radionuclides to be used by nuclear decision-support systems (DSSs), which thereby provide a more comprehensive basis for the decision making.

Short-range atmospheric dispersion models differ from long-range models not only by the use of finer resolution terrain and land-use data, but also by the fact that short-range models may utilize weather radar data for simulation of wet deposition of radionuclides. Obviously, observational data, e.g. from radars, can be used for hindcasting, but these data, which are expected to represent the precipitation intensity more accurately than NWP model data, are useful for nuclear emergency preparedness in the period of time until radiological monitoring data have become available. However, there are a number of uncertainties associated with such use of weather radar data. These include the use of parameterization of the precipitation rate depending on the attenuation of the reflected radar signal, filtering of false radar echoes arising from e.g. clutter or flocks of birds, precipitation from low clouds not being registered by the radar beam, and precipitation evaporating before reaching ground. A new possobility is facilitated by the next-generation dual-pole Doppler radars, namely observed distinction between rain and snow which can have important consequences for short-range modelling since deposition of radionuclides differs substantially between rain and snow.

Thus, the MESO project has two work packages: one devoted to the study of uncertainties of short-range atmospheric dispersion forecasting involving the use of NWP model data only, the other focusing on hindcasting including the combined use of NWP model data and weather radar data.

DMI's role: Coordination, ensemble-statistical application of the RIMPUFF short-range dispersion model, generation of precipitation intensity from weather radar data and description og uncertainties and potential errors.

MODEXTREME: Agriculture facing extreme climatic events (link: english (external))

Project aims: MODEXTREME has the overarching goal to help the European and non-European agriculture face extreme climatic events by improving the capability of biophysical models simulating vegetation responses to integrate climatic variability and extremes. MODEXTREME seeks to identify and integrate into simulation models the responses of main crop and grassland systems to environmental conditions associated with extreme climatic events. MODEXTREME will improve yield monitoring and forecasting systems via multiple observational constraints to be assimilated into process-based models across different climate conditions. MODEXTREME will also estimate possible trajectories of agricultural productivity in the short (during current season) to medium time horizons and associated uncertainties. This involves taking into account the genetic progress and its effects on responses to extreme environmental conditions.

Project aims: The North Atlantic Ocean is one of the most important drivers for the global ocean circulation and its variability on time scales beyond inter-annual. Global climate variability is to a large extent triggered by changes in the North Atlantic sea surface state. The quality and skill of climate predictions depends crucially on a good knowledge of the northern sea surface temperatures (SST) and sea ice distributions. On a regional scale, these parameters strongly impact on weather and climate in Europe, determining precipitation patterns and strengths as well as changes in temperature and wind patterns. NACLIM aims at investigating and quantifying the predictability on interannual to decadal time scales of the climate in the North Atlantic/European sector related to North Atlantic/Arctic Ocean surface state (SST and sea ice) variability and change.

ORCA - Oceanic Response, Controls and Attribution: west Greenland fjord circulation and accelerating glacier discharge

Project aims: In this project we propose to investigate the hydrography and circulation in the double-fjord system into which the outlet glaciers Rink and the Kangerdlugsupp Sermerssua terminate. These two tidal glaciers have shown very different dynamical response during recent years while they have been subject to the same atmospheric and far-field oceanic forcing. We hypothesize that oceanic processes on the fjord scale and smaller must play a role in controlling these glaciers' dynamics. The exchange between the two fjords and the open ocean, and hence heat and freshwater flux, are expected to be different due to the distinct geometries of the two fjords.

SAMAR - Short and long term ablation modelling based on Automatic Weather Station data and Regional Climate Model 

Project aims: The overall goal of the project SAMAR is to improve predictive capabilities of surface energy balance (SEB) models both on short time scales (days and weeks), that are useful for example for operation of hydroelectric power plants and for making flood warnings, and on century time scale for improved projections of the contribution of glaciers to sea level rise. To achieve this overall goal we will take advantage of the wealth of data available in Iceland at IES, and three types of ablation models with various spatial extent and resolution. An SEB model that has been applied for points will be extended to a distributed surface module in HIRHAM5. To include the response of the glacier to the changes in the SEB, HIRHAM5 is coupled to the dynamic ice sheet model PISM for future projections. The objectives of the project are defined as follows:

Objective 1: Develop a distributed SEB model for Icelandic glaciers

Objective 2: Assess the sensitivity of the modelled ablation to variation in albedo and other energy balance components in the model

Objective 3: Validate the SEB module of HIRHAM5 with available observations from AWS and contribute to further development of this module

Objective 4: Validate and apply the coupled HIRHAM5-PISM model on Icelandic glaciers on both short and long time scales as well as with different spatial model resolutions

DMI’s role: Improved parameterisation of SEB in HIRHAM and apply the model to Icelandic glaciers using the PISM Ice Sheet model coupled to HIRHAM

SolarPACES Guidelines for creation of meteorological data sets for CSP performance simulations

Project aims: Proper knowledge of the availability and variability of solar irradiance - in particularly solar direct normal irradiance (DNI) - is the single most important thing for estimating the performance of planned concentrating solar power (CSP) systems. Classically, such performance simulations have been based on some form of typical meteorological year (TMY) data set that includes 12 typical months of data taken from a longer data series of quality controlled meteorological measurements. This approach, however, is lacking in the sense that the typical meteorological months in the data series do not accurately represent the variability of the solar irradiance. By utilizing multi-year data sets, probabilistic modeling can be performed that accounts for the full variability in a longer data series. Best practices for making and utilizing such data sets are needed. Making such guidelines will be the focus of this project.

DMI's role: Project management and investigation of the future variability in the solar resources with a particular focus on the risk of major volcanic eruptions.
