Dear all,
as stated in the general guidelines for the construction of standard
names, a quantity is assumed to apply to the whole area of a
horizontal grid box. Sea-ice usually covers just a part of a grid
cell, so a variable with the standard name "sea_ice_thickness" would
actually describe the average sea-ice thickness in a grid cell. Or,
if c_i is the fraction of a grid cell and h_i is the thickness of
sea-ice, then a variable with standard name sea_ice_thickness would be
c_i * h_i
At least, thats how I interpret the general guidelines. In many
cases, we are interested in the quantity h_i, a standard name for
that would be sea_ice_thickness_where_sea_ice. I would like to
propose this and some other names with the qualifier
"where_sea_ice", which only applies to the fraction of the surface
covered by sea-ice. The names I would like to suggest are
sea_ice_x_velocity_where_sea_ice
sea_ice_y_velocity_where_sea_ice
sea_ice_eastward_velocity_where_sea_ice
sea_ice_northward_velocity_where_sea_ice
sea_ice_thickness_where_sea_ice
The velocities with units of m/s, the thickness with units of m.
Best Regards,
Knut A. Lis?ter
