confused about the cases' names of CCSM

[lixz@ieecas_cn]

I want to download some cases from CCSM. But I don't know the actual informations of these cases such as: b30.020.ES02, b30.030a, etc. Where can I find the introduction of them.
What's the meaning of character "ES" or "ES01", “030b", "030b.ES01". I am waiting for your help.
