The ERA5 re-analysis data, from 1978 until 2019, went live in January 2019. Resolution is 31km compared to 80km for ERA-Interim. Late in 2019 ERA5 re-analysis data from 1950-1978 will also be released. Re-forecasts, which currently use ERA-Interim analyses as the basis for their initialisation, will start using ERA5 analyses for this purpose with cycle 46r1. (ERA5 versus ERA-Interim)
- Can 1 year of re-forecasts be made available immediately with each new cycle ?
