Dear Jonathan,

Yes, it should be 0C, not 0K.


I don't think the approach you suggest will work because what we need is the 
depth of the first 0C isotherm assuming surface temperature above 0C. We don't 
want the depth of the 0C isotherm in regions where the surface temperature is < 
0C. I can't see any way to include these conditions in existing CF attributes, 
can you?


regards,

Martin

Dear Martin

All the change_over_time ones look fine to me, thanks.

Could we use the standard_name of depth for this, with a coordinate
variable of soil_temperature=0degC?
(I think 0degC is intended above, not absolute zero)

Best wishes

Jonathan
