    How to add additional auxinput streams?

    Hi all, I would like to add some new variable inputs into WRF. For example, I need to input 10 variables, all of which are dynamically changing, and each variable has its own distinct timestep. I understand that auxinput5 can handle dynamic inputs(SST,LAI,etc), but I have more than one variable...
