I am looking to increase the number of vertical levels near the surface in my runs.
I want to achieve 2 in the lowest 100m and then around 20 in the first 1/1.5km.
What would be the best way to achieve this, other than just increasing the number of vertical levels?
Could eta_levels be defined to achieve this?
Alternatively how would the dzbot and dzstretch_s and dzstretch_u be used to increase levels near the surface.

Thanks!
 
Hi,
Yes, you would use eta_levels to specify the levels you want. The other variables aren't used for namelist specification. They were added as global attributes. If you're interested, you can take a look at the commit information for the code modification for those particular variables:
