CH4 and DMS for RCP4.5 after 2005

Dear CESM experts, 1) CH4I'm trying to run B compset with super fast chemistry to predict climate in the future with RCP4.5. I found that CH4 used a file_list to read in inputfiles for each decade (1840-2009) in /trunk/inputdata/atm/cam/chem/methane, but I don't find any CH4 setting files for the future. Is there any CH4 inputfile offered by CESM for the RCP4.5 future case? If there's not, is there any guideline to show me how to generate a inputfile by myself?  2) DMS, ISOP, volc_SO2I'm using emission files from this directory: /trunk/inputdata/atm/cam/chem/2000-2100_RCP45. Based on the setting in 2000_cam4_super_fast_llnl.xml, DMS, ISOP, volcano SO2 and SO4 are also required, which did not shown in RCP45 directory. Where are these files? Or how do I figure out which inputfile I actually need? 3) Difference of emission RCP45I found two directory that includes emission under the RCP45 senario: /trunk/inputdata/atm/cam/chem/2000-2100_RCP45 and /trunk/inputdata/atm/cam/chem/emis/rcp45_mz4_2000_2100. What's the diference between these inputfiles? Thank you so much,Pei
