Dear list,
I have a question regarding the use of the standard names of the form
ocean_mixed_layer_thickness_defined_by_*
the definition from the official standard name table is:
"The ocean mixed layer is the upper part of the ocean, regarded as being
well-mixed. The base of the mixed layer defined by temperature, sigma or
sigma_theta is the level at which the quantity indicated differs from its
surface value by a certain amount."
From what I understand, in the case of
ocean_mixed_layer_thickness_defined_by_temperature, I should specify some
quantity as a scalar (Z axis), but it is actually a temperature difference that
I need to encode, not a plain temperature : temp_surf - temp_base_level =
temp_delta_defining_mixed_layer_thickness
if it was simply a temperature I would maybe use:
float swpt ;
swpt:standard_name = "sea_water_potential_temperature" ;
swpt:units = "degC" ;
swpt:axis = "Z" ;
swpt:positive = "down" ;
but what I really want to encode is a temperature difference. How can I specify
that? Is "sea_water_potential_temperature" the correct standard name to use?
same question for ocean_mixed_layer_thickness_defined_by_sigma_theta, how do I
encode a "difference" in sigma_theta?
thanks,
