Re: [ferret_users] query regarding the calculation of zonally averaged ocean heat content in joules rather than joules/m^2

Saurabh,

i hope the land values are automatically taken care by the ferret while making zonal/meridional/box averages. is it so?

It is.  Missing datapoints are regarded as non-existent.  When average is computed, instead of

   (dx1*a1 + dx2*a2 + missing + dx4*a4) / (dx1+dx2+dx3+dx4),

ferret computes

   (dx1*a1 + dx2*a2 + dx4*a4)/(dx1+dx2+dx4).

For integral, it computes

   dx1*a1 + dx2*a2 + dx4*a4,

ignoring the third gridpoint.
