New rules for Colorado’s cloud-seeding program →

Bob Berwyn, reporting over at the Summit County Citizens Voice:

As part of the state-authorized weather modification plan, operators of cloud-seeding operations are required to complete annual “target versus control” analyses, comparing snowfall in target areas against similar non-targeted control areas. Over time, the data from those evaluations may help determine if cloud seeding really does boost snowfall by up to 15 percent, as claimed by the operators.

I’m really interested to learn more about the effectiveness of these cloud seeding programs (do we get more snow and water?) and it sounds like this control analyses will help get us better data. Unfortunately, as he points out later, there was only one opportunity to seed in November. Yikes…
