Description

Hey! Not sure if this was the right place to ask, but I just have a quick question regarding units when saving data for NetCDF.

For things like precipitation, I understand that the default CF convention is in m s-1, but sometimes it would make sense to save in terms of mm s-1 or even mm hr-1. Is it really of utmost necessity to follow the units listed on the CF Standard Names page in http://cfconventions.org/Data/cf-standard-names/70/build/cf-standard-name-table.html or are we allowed some degree of flexibility for units?
