It doesn’t really work like that. For instance, imagine you have a simulation with billions of particles in it. To construct reduced data you may need to use many fields (position, temperature, composition) of all particles over many outputs (usually at different times).
In that case you shouldn’t need to ship the data at all. Just include the code for the simulation and let the rescuers run it to generate the data themselves.
Sorry I'm a bit late to this, but those simulations take 10s - 100s of millions of Cpu hours (i.e. costs of millions - 10s of millions of dollars), so that's not practical.
