Ridge ratio will look like

double si_ridge_ratio(time, y, x) ;
	si_ridge_ratio:_FillValue = -100000000376832. ;
	si_ridge_ratio:standard_name = "sea_ice_volume_fraction_of_ridged_ice" ;
	si_ridge_ratio:long_name = "Sea Ice Volume Fraction of Ridged Ice" ;
	si_ridge_ratio:units = "1" ;
	si_ridge_ratio:cell_methods = "time: mean (interval: 1 hours) area: mean where sea_ice" ;
	si_ridge_ratio:grid_mapping = "stereographic" ;

Sea ice age will look like

double siage(time, y, x) ;
	siage:_FillValue = -100000000376832. ;
	siage:standard_name = "age_of_sea_ice" ;
	siage:long_name = "Age of Sea Ice" ;
	siage:units = "years" ;
	siage:cell_methods = "time: mean (interval: 1 hours) area: mean where sea_ice" ;
	siage:grid_mapping = "stereographic" ;

• note I will change units of moorings outputs to years
• will also change units of siage_det (detectable siage) to years.

Young ice will look like

double siconc_young(time, y, x) ;
	siconc_young:_FillValue = -100000000376832. ;
	siconc_young:standard_name = "sea_ice_classification" ;
	siconc_young:long_name = "Sea Ice Area Fraction of Young Ice" ;
	siconc_young:units = "1" ;
	siconc_young:cell_methods = "time: mean (interval: 1 hours) area: mean" ;
	siconc_young:grid_mapping = "stereographic" ;
