csim4_8_15 was used in CCSM versions ccsm3_0_beta08 and earlier.
csim4_8_16 was used in CCSM versions ccsm3_0_beta09 and later.

Note that in the vector version of the ice model, the method of indexing the conversion factors has been replaced by a less error prone method. This is in versions csim5_0_0 and later.

Here are the variables affected and the factors needed to correct the fields:

Index Number	Variable Name	Erroneous Conversion Factor	Correct Factor
35	Qref	mps_to_cmpdy/dt	kg_to_g
36	growb	mps_to_cmpdy/rhoi	mps_to_cmpdy/dt
37	frazil	mps_to_cmpdy/dt	mps_to_cmpdy/rhoi
41	meltl	secday	mps_to_cmpdy/dt
43	Fsalt_aice	mps_to_cmpdy/rhofresh	secday
45	Fresh_aice	1	mps_to_cmpdy/rhofresh
58	strength	secday*c100	1
61	opening	1	secday*c100
63	sig2	mps_to_cmpdy	1
65	dvidtd	secday*c100	mps_to_cmpdy
67	daidtd	1	secday*c100

To correct the field, multiply the bad field by the correct factor and divide by the erroneous factor.
