[MITgcm-support] Values about adjoint ADJ* results

[Peng Zhan]

Dear all,

I am doing the adjoint sensitivity analysis, but get confused about the
values' physical meaning in the ADJ* results.

For instance, the cost function J is defined using daily average SST over a
box, the ADJ* results are about 10^-7 to 10^-6 in magnitude.

1. Is the surface ADJtheta the sensitivity to SST it self?
2. If yes, the sum of ADJtheta over the box right before the target day
should be close to 1?


Thanks in advance, Peng
