    Additional glacial sea ice/SST configurations
  • CLIMAP. CLIMAP SSTs/sea ice as used in PMIP-1
  • LGM*. SSTs/sea ice from CCSM3 b30.104 simulations
  • stadial. SSTs/sea ice from CCSM3 b30.104 simulation with extra sea ice in the Nordic Seas during winter ("NS" stands for Nordic Seas, "WAtl" stands for the western Atlantic sea ice tongue; the WAtl tongue exists in the b30.104 simulation)
  • stadial-. SSTs/sea ice from CCSM3 b30.104 simulation with (less) extra sea ice in the Nordic Seas during winter ("NS" stands for Nordic Seas, "WAtl" stands for the western Atlantic sea ice tongue; the WAtl tongue exists in the b30.104 simulation)
  • NS. SSTs/sea ice from CCSM3 b30.104 simulation with less sea ice in the Nordic Seas during winter (WAtl tongue is present as in the b30.104 simulation, December-June sea ice in NS has been adjusted to summertime ice line, SSTs have been warmed slightly)
  • WAtl. SSTs/sea ice from CCSM3 b30.104 simulation with less sea ice in the western Atlantic during winter (NS sea ice is present as in the b30.104 simulation, December-June sea ice in WAtl has been adjusted to summertime ice line, SSTs have been warmed slightly)
  • WAtl+NS. SSTs/sea ice from CCSM3 b30.104 simulation with less sea ice in the Nordic Seas and no WAtl tongue during winter
