ERA-Interim nudging data for CAM-Nor from recent years

[DirkOlivie]

We do not have nudging data to drive CAM-Nor for the latest years. On vilje I found data up to January 2017. Inger-Helene used to prepare those fields. Maybe we should try to prepare nudging fields for more recent years.

Hi! I have prepared some more years later and can also share the code: https://github.com/sarambl/ERA_interim2noresm
(Based on Inger Helenes code)

years 2014 and 2015 are also here (didn't have write access to the folders created by others):
/cluster/shared/noresm/inputdata/noresm-only/inputForNudging/SMB/ERA_f19_tn14_gte2014

Would be great if the wind etc files get co-located on one place. Current user wisdom is here:
https://noresm-docs.readthedocs.io/en/latest/configurations/nudged_simulations.html?highlight=nudge#meteorology

Is that still correct?
Maybe we should add the years which are available as preprocessed files, and Saras github to produce new years?

Nudging data should be included on central inputdata storage

Data up until October 2018 exist on Tetralith. Should be checked an possibly copied to Nird / Betzy

ERA interim and ERA5 data should be separated.

I have compared the nudging data on fram
/cluster/shared/noresm/inputdata/noresm-only/inputForNudging/ERA_f09f09_32L_days

with data uploaded by Anna from tetralith to fram
/cluster/shared/noresm/inputdata/noresm-only/inputForNudging/AL/ERA_f09f09_32L_days

The data is different (e.g., 1-2 Pa difference in surface pressure) for January 2016.

I assume that there is a Readme file or information in the files about ERA version?
