[MITgcm-support] [EXTERNAL] How to start from given initial conditions without restarting the simulation

[Shevchenko, Igor]

That's right, I can do it. In fact, this is what I do to start the model from given initial conditions.
What I can't figure out, where there is a possability to specify, say 4 initial conditions, and pick them up at different moments in time (say t=0, 5, 10, 15 as in the example below) without stopping the simulation? 

&PARM05
 bathyFile       = 'bathy.bin',
 hydrogThetaFile = 'Theta.0',
 hydrogSaltFile  = 'Salt.0',
 uVelInitFile    = 'Uvel.0',
 vVelInitFile    = 'Vvel.0',
 pSurfInitFile   = 'Eta.0',

 bathyFile       = 'bathy.bin',
 hydrogThetaFile = 'Theta.5',
 hydrogSaltFile  = 'Salt.5',
 uVelInitFile    = 'Uvel.5,
 vVelInitFile    = 'Vvel.5',
 pSurfInitFile   = 'Eta.5',

 bathyFile       = 'bathy.bin',
 hydrogThetaFile = 'Theta.10',
 hydrogSaltFile  = 'Salt.10',
 uVelInitFile    = 'Uvel.10,
 vVelInitFile    = 'Vvel.10',
 pSurfInitFile   = 'Eta.10',

 bathyFile       = 'bathy.bin',
 hydrogThetaFile = 'Theta.15',
 hydrogSaltFile  = 'Salt.15',
 uVelInitFile    = 'Uvel.15,
 vVelInitFile    = 'Vvel.15',
 pSurfInitFile   = 'Eta.15',

you can specify these fields in data PARM05 directly, e.g.,

# Input datasets
 &PARM05
 bathyFile       = 'bathy.bin',
 hydrogThetaFile = 'Theta.0005184000',
 hydrogSaltFile  = 'Salt.0005184000',
 uVelInitFile    = 'Uvel.0005184000',
 vVelInitFile    = 'Vvel.0005184000',
 pSurfInitFile   = 'Eta.0005184000',
 /

then MITgcm will initialize the other fields automatically

Surely, I can do it, but the problem is that the new initial condition is just a set of fields for U, V, T, S, and Eta, while the pickup file requires much more than that.
