WebThe 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). WebJun 17, 2024 · The ECMWF coupled model represents the complex interactions and feedback mechanisms between atmosphere, land, ocean, sea ice, and waves, with a dedicated DA system used to initialise each component. Coupled DA is about exchanging information between these different DA systems.
WebBy now, the scope has expanded to include more components of the Earth system, such as the land surface, the ocean and the chemical composition of the atmosphere. Copernicus ECMWF provides three types of reanalyses data sets: Global reanalysis gives full global coverage in the horizontal, whereas regional reanalysis only covers a specific ...
