North Unit Irrigation District

Award Purpose: the Recipient Shall Investigate the Feasibility of Cloud Seeding as a Means to Balance Climate Variability and Water Management in the Region. This Study Will Be Done Using Highresolution Numerical Weather Model Running the Latest Subfreezing Cloud Physics Package. the Model Will Run Over Multiple Winters (novapril for 510 Years). This Model Output Will Then Be Used to Count Up the Number of Seedable Hours and the Seedable Cloud Altitudes Over All the Mountain in the Area to Determine Feasibility of Using Cloud Seeding to Augment Snowpack in Oregons Deschutes Basin That Covers Several Counties Including Jefferson, Deschutes, Crook, and Klamath Counties.activities to Be Performed: Task 1: Development of Cloud Seeding Model. This Task Includes the Following: a Qualified Contractor Will Develop a Highresolution Weather Model That Can Produce Three Dimensional Results on an Hourly Timestep. the Model Will Output Clouds, Temperature, and Wind Data. Inputs of the Model Will Include Regional Weather Data From the NWS and Other Publicly Available Sources. the Contractor Will Produce Multiple Winters of Simulations That Will Be Used for Task Two.task 2: Evaluation of Model Results for Feasibility of Cloud Seeding. This Task Includes the Following: a Qualified Contractor Will Take the Modeling Results and Determine the Seedability of Storms by Analyzing Temperature, Vertical and Horizontal Wind Components, and Atmospheric Stability. the Model Needs to Show the Storms Deschutes Basin Cloud Seeding Feasibility Investigation 8 Simulated Are Cold Enough That Seeding Materials Can Reach an Activation Temperature and Wind Direction Needs to Ensure Materials Can Be Dispersed. Results Will Be Documented in a Report Reviewed by Regional Experts at the 30% Draft Report, 60% Draft Report, 90% Draft Report, and Final Report. Task 3: Report Review Process. This Task Includes the Following: North Unit Irrigation District Will Contract With Regional and National Experts to Review and Comment on the Initial Results and Associated Documentation and Review and Comment on the 60% Draft Report, and 90% Draft Report. Webinar Presentation. Reclamation May Request the Recipient to Participate in a Reclamation-sponsored Webinar to Discuss Application of Deliverables to Management Questions. the Presentation Should Inform Reclamation About Project Accomplishments, the Final Results of the Identified Tasks, and Any Lessons Learned.expected Deliverables or Outcomes: for the Feasibility of Cloud Seeding as a Means to Balance Climate Variability and Water Management in Other Regions for Snow Pack to Have Water.intended Beneficiaries: Public, Anyone Interested in the Data and Methods for Cloud Seedingsubrecipient Activities (if Known or Specified at Time of Award): Na
