Working with models and data

Computer models are one of the main tools of climate research. They assist in predicting, for example, how climate changes according to different scenarios of economic and social development. Moreover, reconstructing past climates is unimaginable without sophisticated models and statistical methods. The reliability of outputs from model simulations can only be determined once they have been compared with measured data. Researchers obtain this data from natural climatic archives such as glaciers or growth rings of trees, as well as from historical documents. The NCCR Climate is adapting existing models, which are applicable on a global scale, for use on a regional level.
