Production of real time predictions (updated for November 2021)

1. Atmospheric ICs:

• Download all the ICs until the 31st October ICs when available (3-4 week daly for real time data/not the final) → This is done extending the autosubmit experiment (a2k7)

Performing the predictions Ocean/Sea Ice ICs: Download the latest ORAS5 and EN4 data up to October/November? 2021 (what’s the delay in publishing the data?) → to check with PA what’s available Regridding/reformatting some of the 3D fields (cdo/sosie) → EN4 Vladimir, ORAS5 Juan (Juan’s method/script was used for the earlier part of the reconstruction) to process the 2021 files already available Downloading the atmospheric forcing files from ERA5 real time dataset up to October (3-4 weeks delay) → Etienne to launch the downloading of the files available Post-process the atmospheric forcing files (which should also correct the precipitation values) → Vladimir will post-process them Applying the random perturbations to the forcings to generate 5 different files → Juan to apply the perturbations when forcing files have been post-processed Producing the ocean-sea ice reconstruction

tests? Putting all scripts in the CPG repository and document it on the wiki (we should also update the respective gitlab issue add issue number)
