<br />'". .. <br /> <br />The operating area for the proposed research is relatively limited, <br /> <br />Seeding material releases will be from an aircraft flying in a tight circle <br /> <br />just upwind of the orographic cloud system. This will generally be <br /> <br />near Craig, Colorado. The purpose of the experiment <br /> <br />is to study the process of nucleation immediately after the seeding material <br /> <br />enters the cloud. The primary target area where an effect on snowfall might <br /> <br />occur and the total area of effect are shown on Attachment l. Specifically, <br /> <br />it includes the triangle formed by the towns of Craig, Kings Canyon, and <br /> <br />Tabernash. Seeding material release will be done only on those periods when <br /> <br />the wind flow is within l50 of 2~OO,_(westerly w~n~,~) _:~~1l0~ the research <br /> <br />aircraft to remain within the spec1f~ed ~arget area. <br />------ <br /> <br />c.

Weather Data Available <br /> <br />The data available at CSU include synoptic surface and upper <br /> <br />air charts, rawinsonde data from the NWS national network, daily <br /> <br />rawinsonde observations made at the project upper air station, Craig, <br /> <br />local weather observations, weather satellite pictures, forecast charts and <br /> <br />bulletins prepared by the National Weather Service. <br /> <br />Aircraft flight planning, winds, upper level temperature and landing <br /> <br />weather will be available from the Denver flight Service Station. <br />
