1. Access to reanalyses
ERA-CLIM2 reanalyses can be accessed from dedicated data portals:
2. Access to observations rescued and reprocessed within the ERA-CLIM2 project
The ERA-CLIM2 observations feed into existing repositories and are already used in other projects (see Brönnimann et al, 2018, BAMS, in press). By submitting data to existing repositories (from where they are retrieved for reanalyses projects), they become part of their update cycles. This guarantees that version numbers are unique and that older versions remain available.
