The
Latitude interval (for 0.14°) in data.exf is not equally spaced distributed. I
have not found the configuration for resolution 0.25°(<a href="https://github.com/MITgcm-contrib/llc_hires">https://github.com/MITgcm-contrib/llc_hires</a>
). So I set the latitude interval equally spaced(file attached).I want to know
if this configuration right. Or can anybody teach me how to set this(for 0.25)?
