Figure 2,15. Example of Seed-Control simulated precipitation difference analysis.

To further investigate the unexpected simulated seed vs. no-seed
precipitation sensitivities before beginning the full set of control and seed
production runs, a series of sensitivity tests were performed. These tests
involved one or more of the following: the background IFN concentration;
constant background IFN concentration fields vs. initial concentrations that
could evolve through advection and diffusion; the number of IFN released per
gram of Agl burned; several rates of Agl activation based on a range of
empirically derived possibilities; and the inclusion of a second cloud water
mode, which along with the standard mode provided a bimodal cloud water
