n1850.ne30_tn14.hybrid.20240829

[mvertens]

Purpose:
Exactly like n1850.ne30_tn14.hybrid.20240822 EXCEPT

• fix for restart problems across year boundaries
• addition of aerocom diagnostics
• NOTE: a memory leak is present in the run and hits agains the node limit when running past 11 years.
  See memory leak in n1850 case NorESM#550
• NOTE: the goal is to run 20 years. When that is done - the code will be moved to /nird/datalake.
