adjoint sensitivity data of the Gulf Stream Index variability

The data include:1) EOF weights of the definition of GSI (gsi_maskC_v06r4unadjv42). The objective function is defined by summing the product of the weights and ocean temperature at 200 m.2) Weekly adjoint sensitivity data of GSI to surface wind stress, net heat flux, and E-P-runoff. The sensitivity results contain the adjoint sensitivity results to the objective function at 12 months of the year 2002, by defining the period of the objective function as these months from January to December. Each of the gsi_m[01-12]_y2002_adxx.tar.gz contains 4 adxx files with the adjoint sensitivity to tauu, tauv, Qnet and EmPmR. The file can be read by gcmfaces tool (https://github.com/MITgcm/gcmfaces).
