Why use ncol as dimension instead of lat,lon #71

Closed aperezvelasco closed 11 months ago

aperezvelasco commented 11 months ago

Hi,

Could somebody give me some background of why only one spatial dimension (ncol) is used to define the spatial structure instead of two spatial dimensions (lat, lon) as is done in the standard way?

What benefits are associated with it?

Thanks beforehand for your responses!

Hello @aperezvelasco! Apologies for the delayed response. The spatial dimension is ncol and not lat, lon because E3SM-MMF uses a spectral element grid.

Happy holidays!
