CLM Offline Simulation Descriptions
  • hyd_off_con3 (CAM3/CLM3 release code, started in 1948)
  • hydp2_off_communn_hk44 (hk44 community hydrology, initialized from hk43)
  • hydp2_off_communn_hk44_effp (same as hk44 but with eff_porosity fix)

    • CAM/CLM Simulation Descriptions - Eulerian core
  • hyd_con (CAM3/CLM3 release code with standard SSTs)
  • hyd_sst (same as hyd_con but with new SSTs [/HANNAY/AMIP/SST-1949_2004/amipbc_sst_T42_1949_2004.nc])
  • hydp2_communn_hk44c (hk44 community hydrology, initialized from end of hydp2_off_communn_hk44, climo SSTs)
  • hydp2_communn_hk44a (hk44 community hydrology, initialized from end of hydp2_off_communn_hk44a, AMIP SSTs)
  • clm350_cam3_4_10a (clm3.5 with cam3_4_10, initialized from end of hydp2_off_communn_hk44a, AMIP SSTs)

    • CAM/CLM Simulation Descriptions - FV core
  • cam3_3_fv_1.9x2.5 (AMIP SSTs, AMWG Control - cam3_3_17 tag: contains clm3_expa_66)
  • cam3_3_fv_con (AMIP SSTs, same as cam3_3_fv_1.9x2.5 but cam3_3_42 tag: contains clm3_expa_79)
  • cam3_3_fv_expa85 (Climate SSTs, same as cam3_3_fv_con but using clm3_expa_85 which has communnity hydrology (tags 80 and 81), water balance error fix (tag 82), snow age fix (tag 83), new smpso/smpsc (tag 84), top soil evaporation fix (tag 85), also includes fmax divide by 100 fix (tag 86))
  • cam3_3_fv_expa85a (AMIP SSTs, same as cam3_3_fv_expa85)
