Make PLD temperature dependent

My modelling domain has a large latitutidal gradient and therefire I'd like to specify PLD (i.e. The duration of larval transport) a function of temperature using some kind of a decay curve or a function based on empirical data. Would this be possible and how would one go about this? 
Thanks

Hi Joe

I am not sure to undertand your question. What does PLD mean?

Hi Nicolas,
PLD = The duration of larval transport
~J

Sorry, I did not see you explained that in your first mail. So far, PLD is fixed all over the simulation and for all particles.

What you would like is that for a given particle, its transport duration depends on the temperature at the release location?

Hi Nicolas,

Precisely,

Hi Joe.

Nothing like this exists in the current version of the code. However, it seems that Lysel Garavelli has already done something like this. We will contact her to know if she can help us to answer your question.

In the time mean, you can still run Ichthyop with the highest larval duration stage and post-process your data to take into account the PLD as a function of temperature, depending on the release position.

Hi Joe

I have checked, and seemingly the only thing that is possible is to use lethal temperatures, which will kill your particules if it's too hot or too cold.

To do it, go in the "Advanced --> Biology --> Lethal temperature" setting page. Then check the "Enable" and "Show hidden parameters". 

You will be able to see the java class that handles this kind of mortality. You can eventually work out a new class based on this one.

makes sense, though it is not exactly the functionality I am after but should do.  Thanks heaps!
