[MITgcm-support] adjoint example

[BIN ZHAO]

Hi all,
  I just begin working on the adjoint of the MITgcm.
  As a first step, I tried the example in c51/verification/global_ocean.90x40x15.
  I compiled and ran the adjoint model for a short period of time(7 days) with only ALLOW_COST_ATLANTIC_HEAT, and I got reasonal sensitivities. But when I ran it for 1 year, the sensitivity values just went crazy(10^54?). Can anyone tell me what is wrong here?
Thanks,
Bin Zhao
