GCMresultat

GCMresultat is a term used in climate science to denote the output produced by a Global Climate Model (GCM) simulation. In languages such as Danish, Norwegian, or Swedish, the compound “GCMresultat” refers to the model’s projected climate state under a defined scenario. A GCMresultat typically comprises spatially distributed fields of climate variables—such as surface temperature, precipitation, humidity, wind, and sea level pressure—as well as derived indicators like extreme weather indices and regional climate patterns. Projections are usually produced for future periods, for example the mid- to late 21st century, under specified emission or socio-economic scenarios (such as RCPs and, in newer studies, SSPs).

GCMresultat often originates from multi-model ensembles (for example CMIP6) to capture the range of possible outcomes across different models. The raw outputs are commonly provided in standard data formats such as NetCDF and are accompanied by visualizations, summary statistics, and documentation. Researchers frequently apply post-processing steps, including downscaling and bias correction, to make the results more suitable for local or regional impact assessments.

Interpretation of a GCMresultat requires consideration of uncertainties. These arise from model structure and parameterizations, the chosen emission or socio-economic scenario, and natural internal climate variability. While GCMresults are essential for understanding potential future climate changes, they are not precise forecasts and are used in conjunction with risk analysis, scenario planning, and policy development to inform adaptation strategies.
