Rainfall increases of seeded (s) clouds versus unseeded (ns) clouds are documented regularly in Texas. The ability to identify and track echoes and calculate their properties with time makes TITAN a potential tool for the evaluation of cloud seeding experiments. Such evaluations are fairly straightforward and compare fields like the lifetime, area, volume and rainfall mass of seeded clouds to clouds that were left unseeded, therefore acting as a control.  A control cloud is an unseeded cloud that lives in the same environment as its seeded partner, in similar synoptic conditions, at similar distance to the radar and from the same day.  The control cloud is than run through a model to give the selected control cloud the same initial condition as that of the seeded cloud.
