	50	!! Introduction : \|
	51	!! -------------- \|
	52	!! Every ice-covered grid cell is characterized by a series of state \|
	53	!! variables. To account for unresolved spatial variability in ice \|
	54	!! thickness, the ice cover in divided in ice thickness categories. \|
	55	!! \|
	56	!! Sea ice state variables depend on the ice thickness category \|
	57	!! \|
	58	!! Those variables are divided into two groups \|
	59	!! * Extensive (or global) variables. \|
	60	!! These are the variables that are transported by all means \|
	61	!! * Intensive (or equivalent) variables. \|
	62	!! These are the variables that are either physically more \|
	63	!! meaningful and/or used in ice thermodynamics \|
	64	!! \|
	65	!! Routines in limvar.F90 perform conversions \|
	66	!! - lim_var_glo2eqv : from global to equivalent variables \|
	67	!! - lim_var_eqv2glo : from equivalent to global variables \|
	68	!! \|
	69	!! For various purposes, the sea ice state variables have sometimes \|
	70	!! to be aggregated over all ice thickness categories. This operation \|
	71	!! is done in : \|
	72	!! - lim_var_agg \|
	73	!! \|
	74	!! in icestp.F90, the routines that compute the changes in the ice \|
	75	!! state variables are called \|
[8407]	76	!! - ice_rhg : ice dynamics \|
[8409]	77	!! - ice_adv : ice advection \|
	78	!! - ice_rdgrft : ice ridging and rafting \|
[834]	79	!! - lim_thd : ice halo-thermodynamics \|
	80	!! - lim_itd_th : thermodynamic changes in ice thickness distribution \|
	81	!! and creation of new ice \|
	82	!! \|
	83	!! See the associated routines for more information \|
