Tco1279 ensemble initial conditions derived from ERA5 and IFS Cycle 48R1 for the PREDDYCT project

Title Tco1279 ensemble initial conditions derived from ERA5 and IFS Cycle 48R1 for the PREDDYCT project
Description The step=0 data from these experiments provides Tco1279 initial conditions derived from ERA5 and IFS CY48R1.1. The type=pf members include perturbations from the ERA5 EDA and singular vectors calculated using IFS CY48R1.1.
