Release passive tracers at a certain time instead of begining

#1 Unread post by auroralin »

Hi, all.

I would like to release tracers at a certain time after model initialization (just like to release floats at Ft0 after initialization), but I dont know how to do that. Would there be a way to realize that?

Welcome to any thoughts and ideas, thanks ;)

The only way to do this is to stop the model, add the passive dye to the last history file, and restart with the modified file as initial conditions.

Hi,

I had a similar issue some time ago, releasing a passive tracer into operational simulations at t = t0 + 1 day. I solved this by modifying some code in step3d_t.F, following the suggestions given in https://www.myroms.org/forum/viewtopic. ... 969#p22969.

Best regards,

Marc

Depending on what you're trying to achieve, passive tracers can also be introduced via rivers. And you can adjust their concentration to only release at a certain time.
