transform operator for adjoint sensitivity

#1 Unread post by xiaocongM »

Dear ROMS users,
The sensitivity to state variable or initial variables is simply the output of adjoint model. As I know, the sensitivity to wind stress is not straightforward and requires operator P which transforms forcing to its representation on the state vector. Could anyone give me more details about the elements of P so that I can construct it more reasonably. Thank you very much!
The reference paper related to adjoint sensitivity is in this paper, but I feel confused about that. "A central California coastal ocean modeling study: 2. Adjoint sensitivities to local and remote forcing mechanisms"VENEZIANI(2009).
