ECMWF Integrated Forecasting System (IFS) CY45R1 deployed on ECMWF computing facilities using allocation for ECMWF special project spgbleac.

This involved running a series of experiments set up and run on the ECMWF system alongside use of operational forecast run data and subsequent hindcast data products. Model runs were run globally, though output were taken on both global and and European area domains for archiving. EU domain has more comprehensive range of parameters archived.

For details of the model runs see Leach et al. (2021) in the linked documentation on this record.
