14. Exhibit N: "Aerosols, Climate and the Hydrological Cycle ", Ramanathan, Crutzen, Kiehl, and <br />Rosenfeld, Science Magazine, Volume 294, December 7, 2001, submitted via email by Brad <br />Udall, Director, Western Water Assessment, NOAA Earth Systems Research Laboratory in <br />Boulder, Colorado. "Human activities are releasing tiny particles (aerosols) into the atmosphere. <br />These human -made aerosols enhance scattering and absorption of solar radiation. They also <br />produce brighter clouds that are less efficient at releasing precipitation. These in turn lead to large <br />reductions in the amount of solar irradiance reaching Earth's surface, a corresponding increase in <br />solar heating of the atmosphere, changes in the atmospheric temperature structure, suppression o <br />rainfall, and less efficient removal of pollutants. These aerosol effects can lead to a weaker <br />hydrological cycle, which connects directly to the availability and quality of fresh water, a major <br />environmental issue of the 21St century." <br />15. Exhibit O: Climate Change in Colorado fact sheet stating that Colorado has warmed 2 degrees <br />Fahrenheit between 1977 and 2006. The full report can be found at http://cwcb.state.co.us/public- <br />information/publications/ Documents /R portsStudies /ClimateChangeReportFull.pdf <br />16. Exhibit P: Flyer from rain observer training sessions and sign in sheets previous meetings. The <br />CWCB has made attempts to develop observations outside of the target area that may need to <br />become an automated network of rain measurements. The issue for hail observations will be more <br />complex as there is no automated way to collect hail pads. SCF will need to continue to collect <br />rain and hail data on the farm and the CWCB will continue to develop rain and hail data <br />observations out of target area. The CWCB may require a minimum of five automated tipping <br />bucket rain gauges with data loggers to be deployed: 1) upwind, 2) in target area, 3) downwind, <br />4) crosswind (north of the hail cannon network, and 5) crosswind (south of the hail cannon <br />network. <br />17. Exhibit Q: "The importance of acoustic cavitation in the sonocrystallisation of ice — high speed <br />observations of a single acoustic bubble ", by Rachel Chow et. al, 2003 IEEE Ultrasonics <br />Symposium. This study was provided to Colorado by the Texas Department of Licensing and <br />Regulation in 2006 and was part of a hail cannon public hearing in Texas. <br />18. Exhibit R: "High -Speed Observations of the Nucleation of Ice by Power Ultrasound ", by Rachel <br />Chow et. al. Exhibits GG and HH were sent to the CWCB for this hearing by George Bomar, <br />Texas Department of Licensing and Regulations. He is a meteorologist and the regulatory and <br />permitting officer for weather modification for the state of Texas.. This study was provided to <br />Colorado by the Texas Department of Licensing and Regulation in 2006 and was part of a hail <br />cannon public hearing in Texas. Although these two studies do not relate directly to the cause and <br />effect relationships of hail cannons on hailstorms they are relevant because they are evidence that <br />sound vibrations have an effect on ice crystal formulation <br />19. Exhibit S: May 18, 1999 letter and attached paper to government officials in Argentina from <br />Brant Foote of the National Center for Atmospheric Research in Boulder, Colorado stating, "In <br />short, there is no evidence whatsoever that the shooting of cannons from the ground has any <br />effect on clouds, on rain, or on hail." <br />20. Public hearing statements from Mike Jones of Southern Colorado Farms. This is the fourth five <br />year permitting period and most of the same people were here were at those hearings in 2001 and <br />2006. Same number of cannons in Saguache County northeast of Center with ten cannons. We <br />2 <br />
