<br />e <br /> <br />e <br /> <br />- <br /> <br />.. <br /> <br />averaging windows equal does not interfere with getting necessary data <br />for the calculation of response variab11~s. <br /> <br />4. The choice of primary aircraft response variables for SCPP-l con- <br />tinue good. One additional aircraft response variable has been added at <br />10 minutes at the -11 Oc altitude in the hopes of documenting initi a1 <br />precipitation growth in the treated clouds. However, the effect from <br />SCPP-1 appears to occur and be confined during the first 60 minutes <br />after seeding. The radar response v clri ab 1 es st ill are quest ionab 1e. <br />Therefore, a" new response variate at 15 minutes after seeding \lIas added <br />to see the expected effect of earlie,' precipitation formation. The <br />radar response v ari ab 1 e at 60 minutes ,after seeding was made secondary <br />rather than primary. <br /> <br />5. There are strong indications that evaluating IICII and "011 class <br />clouds during SCPP-1 conditions are impossible with current observation <br />_ systems. Therefore, it has been decided to del ete these c1 asses from <br />the SCPP-l randomi zed experiment. <br /> <br />.6. There are indications that certain portions of orographic/area-wide <br />precipitation events are more seedab1e. <br /> <br />7. The radiometer has proved to be a useful tool in situations where <br />the temperature at the site is below frE!ezing. However, with precipita- <br />tion above freezing, degradation of the liquid and vapor information is <br />apparent. <br /> <br />It has been decided to move the radiometer to a higher site within about <br />5 km of the crest to minimize these situations.
