LACK OF FUTURE SURF DATA FOR CLM

Hello everyoneI was running CESM1.1.2 with FMOZ component, and would want to further investigate how would landuse change impact the climate.The futrue land use projection under scenario of RCP has been published (e.g. Hurtt, 2011), I also found many data sets in https://svn-ccsm-inputdata.cgd.ucar. edu/trunk/inputdata/lnd/clm2/. However, I wonder why the parameters of PCT_URBAN (urban land fraction) were the same in the three files below.fl1=surfdata.pftdyn_1.9x2.5_rcp8.5_simyr1850-2100_c121015.ncfl2= surfdata_1.9x2.5_simyr2000_c091005.ncfl3=surfdata_1.9x2.5_urb3den_simyr1850_c090316.ncI also checked the log file of  surfdata_0.23x0.31_rcp8.5_simyr2100_c110706.nc, and found the urban data was from /fs/cgd/csm/inputdata/lnd/clm2/rawdata/mksrf_urban_3den_0.5x0.5_simyr2000.c090223_v1.nc. How can I get the right land use data of RCP future projection? I would apperciate it if anyone do me a favor.
