[MITgcm-support] Time-Varying Ptracer Concentration

[Weiyang Bao]

Dear MITgcm users,

I’m trying to introduce two passive tracers at a selected region of my coastal model domain. In order to estimate the “age” (time elapsed) of the tracer since it was introduced, one of the tracers need to have a steady input with a concentration say 1, the other tracer should have a concentration that grows at a known rate, say 1, 2, 3,… at time 1, 2, 3,… and the ratio of these two tracers can be used to estimate. I’ve figured out using the RBCS package to relax the first tracer and maintain a continuous concentration of unity, but not sure how to generate the time-varying (or linearly increasing) concentration for the second tracer. It will be much appreciated if you could share some ideas.

Thanks for your time,

Weiyang
