5.3 Sensitivity of Air-Sea Exchange to Tracer Injection Site

The MITGCM has been adapted to enable AD using TAMC or TAF. The present description, therefore, is specific to the use of TAMC or TAF as AD tool. The following sections describe the steps which are necessary to generate a tangent linear or adjoint model of the MITGCM. We take as an example the sensitivity of carbon sequestration in the ocean. The AD-relevant hooks in the code are sketched in 5.2, 5.4.
