Below is an example of information you can get about the MOC from a CCSM4 pop history file, $CASE.pop.h.$date.nc.
The actual values for transport_components and transport_regions are case- and resolution-dependent, so the example below may or may not match the information from your case. To get the information for your case, issue the following command on your $CASE.pop.h.$date.nc file:
ncdump -v MOC,moc_components,transport_components,transport_regions $CASE.pop.h.$date.nc
Here's an example of the output from this command:
float MOC(time, transport_reg, moc_comp, moc_z, lat_aux_grid) ;
MOC:long_name = "Meridional Overturning Circulation" ;
MOC:units = "Sverdrups" ;
MOC:coordinates = "lat_aux_grid moc_z moc_components transport_region time" ;
MOC:missing_value = 9.96921e+36f ;
char moc_components(moc_comp, nchar) ;
moc_components:long_name = "MOC component names" ;
moc_components:units = "" ;
char transport_components(transport_comp, nchar) ;
transport_components:long_name = "T,S transport components" ;
transport_components:units = "" ;
char transport_regions(transport_reg, nchar) ;
transport_regions:long_name = "regions for all transport diagnostics" ;
transport_regions:units = "" ;
moc_components =
"Eulerian Mean",
"Eddy-Induced (bolus)",
"Submeso" ;
transport_components =
"Total",
"Eulerian-Mean Advection",
"Eddy-Induced Advection (bolus) + Diffusion",
"Eddy-Induced (bolus) Advection",
"Submeso Advection" ;
transport_regions =
"Global Ocean - Marginal Seas",
"Atlantic Ocean + Mediterranean Sea + Labrador Sea + GIN Sea + Arctic Ocean + Hudson Bay" ;
