The Copernicus Arctic Regional Reanalysis (CARRA) is a high resolution (2.5 km) reanalysis system for two domains of the European part of the Arctic (Figure 1). The CARRA dataset covers the period from September, 1990 and onward (timely updates are planned to be provided until June 2025). CARRA adds value to the ERA5 global reanalysis with the use of more (local) observations, with the focus on the representation of important local processes like cold surfaces and with its higher spatial horizontal resolution which allows for more details. The CARRA system is described in its Full System Documentation, while some key points of the configuration of the system is compared to ERA5 in Table 1.
