Target Area Rawinsonde - KVlRB Upper Air Station Extra-Area Stom Surveillance - NWS Radar, Telefacsiroile repeater Operating Area Stom Data - Project Radar 5.4 Seedability Forecasts - Daily Operating recisions Each day seedability forecasts will be prepared by the Project Director, using the infonnation available fran the sources shown in paragraFh 5. 3. '.!he criteria described in paragraFhs 5.1 and 5.2 will serve as a guide in making the seed, ro-seed decision. Nonnally by 10:30 a.m. (cur) sufficient weather data is available to give a good indication of the cloud ronditions that will affect the project area for the ensuing 24 hours. At this tine the seeding plans for the day will be issued to air crews and maintenance personnel. If seedable ronditions are expected, the crews will be given details about standby status, seeding strategy, seeding rates and expected duration of the cloud system. If no seedable clouds are expected, the crews will be placed on appropriate standby status for recall in the event unpredicted stonns threaten the project area. Figure 2 is a flCMchart of events which take place on a typical day. '.!he initial daily operating decisions are made on the basis of forecast infonnation and cloud nodel calculations. While the data inputs are very useful in ~rking out crfM sc.~edules and seeding strategy, they are not the only factors for making final seeding decisions. For ~rking out the final seeding strategy, the Project Director will also use real-tine observations obtained fran the project radar and pilot reports. 5.5 Coordination lvith Other Projects Plans published by the Bureau of Reclamation indicate a rontinuation of HIPlEX research in Northwest Kansas. Every effort will be made to cooperate with them in their research activities. Procedures will be established to ensure a minimum of interference with the HIPlEX project. 'Ihese will include notifica- tion of seeding activity which may affect the research operation. l'l'nen operating in that portion of the Muddy Road project area which overlaps the HIPlEX experimental area, aircraft will establish radio rontact with the radar facility at G:xxlland and operate their trans- ponders at the identification rode requested by the rontroller. Surrm3.1:Y reports of Muddy Road seeding locations and anounts will be forwarded to the HIPLEX group on a rronthly basis.
