Data Variables

What is a climate indicator?

Climate Indicators (CI) are: Summaries of past and projected climate change, observed and projected  changes affecting nature and society; Condensed climate information for climate impact assessment so users do not have…

What is CMIP and CORDEX?

Climate Indicators (CI) are available in the two tools of Climate Information; the Site-Specific report and the Data Access platform. The CI are calculated from ensembles of Global and Regional Climate…

What do different RCPs mean?

Future greenhouse gas emissions and concentrations are difficult to predict and depend on future developments such as future population growth, economic growth, energy use, uptake of renewable energy, technological change,…

What is a climate model and projections?

A climate model is a set of numerical simulations of important physical process involving the land, atmosphere, ocean, and ice-covered regions around the globe. Climate models are used to simulate…

Data Production and Tailoring

How to produce climate indicators?

Climate Indicators are calculated from two well trusted and globally known climate scientific communities: Global Climate Models (GCM) used in the Coupled Model Intercomparison project Phase 5 (CMIP5) Coordinated Regional…

What is Statistical and Dynamical downscaling?

Global Climate Models (GCMs) are important tools to assess the impact of future greenhouse gas concentration on changes in temperature, precipitation and wind speed. However GCMs are run at a very coarse…

Why is there a spread of values in the Ensembles?

The estimates of climate-change impact include large uncertainties, therefore an ensemble of projections is presented. The ensembles contain a spread of values that reflect the lack of knowledge, for instance…

Why use a model ensemble?

A climate model is a numerical representation of the climate system, and thus not a perfect description of the system. The description of the physical laws governing the climate system…

Confidence and Robustness

How to interpret ensemble value range?

The ensemble value range (interquartile range) is a confidence measure that provides information about the ensemble spread of the projected climate change signals. The ensemble value range indicates the range…

How to explore confidence in the data?

The data and results are based on state of the art modelling systems combining widely used regional climate models and three different large scale hydrological models. The indicator data presented in the…
