Simulation settings

Control: main branch api 25

  • Site: CZ2
  • Meteorology: 1900-1999
  • Simulation length: 100 years
  • Nignitions: 0.25 km-1 yr-1
  • Case name: CZ2_I2000Clm51Fates_api25_main-branch_TEST.C17e2acb6a-Fe663a6e6.2023-01-19

Test: cwd_partitioning_branch

  • Same as control, but with new cwd_partitioning scheme
  • Case name: CZ2_I2000Clm51Fates_api25_main-branch_TEST.C17e2acb6a-Fe663a6e6.2023-01-19

Both use best param file (01-26-23) before:

  • Charlie’s additional oak params
  • cwd_partitioning
  • resprouting

Composition is affected

Composition is good for CZ2. Shrubs die out, likely because fires are not creating open-enough patches.

Control

Shrubs die out faster, likely due to more canopy closure, cedar does a little better

CWD-change

Pine, cedar, fir, oak, shrub
