Scope of Work <br /> <br />3.1 Basic Research Study by CSU Team <br /> <br />The proposed basic research study involves the following tasks: <br /> <br />1) Set up RAMS with a fine grid having 3-km grid spacing over the Denver <br />Water Department program's catchment area and over the locations of the <br />ground-based seeding generators. <br />2) Implement algorithms simulating cloud seeding generators as sources of IFN <br />at specific ground-based sites. <br />3) Perform simulations of Lagrangian transport of seeding materials on selected <br />days covering a range of wind and stability regimes. <br />4) Perform forecasts for seeded and non-seeded days. <br />5) Perform evaluations of model predictions of precipitation using MRBP. <br />6) Research study supervision and preparation of quarterly and annual reports. <br /> <br />Scope for Task #1: Set up RAMS <br /> <br />This task is fairly routine for the CSU team and will require only 0.5 month for Ray <br />McAnelly to set up and test out the model for the Denver Water Department program <br />area. The only difficulty may be with the placement of the grids so that particular <br />problems are not encountered with the fine grid boundaries over this complex terrain. <br /> <br />Scope for Task #2: Implement algorithms <br /> <br />This task requires modifying the RAMS source code to include specific seeding generator <br />locations and operational periods, and a translation of generator mass production rates <br />into model forecast variables for IFN concentrations. Gustavo Carrio will perform this <br />task and it will require 1.0 month. <br /> <br />Scope for Task #3: Perform simulations <br /> <br />This task first involves selecting certain meteorological regimes that impact the transport <br />and dispersion of seeding material and then identify case study days that represent those <br />regimes. Then perform Lagrangian trajectory analyses using model output data to <br />examine the predicted trajectories and the extent to which they interact with clouds in the <br />area. We expect that 6 to 12 days will be required. Ray McAnelly will spend 1.5 months <br />on this task. <br /> <br />Scope of Task #4: Perform forecasts <br /> <br />The operation of the forecast model is fully automated. But, on occasion data transfers <br />from NCEP and computer hardware downtime will require reruns of the model and <br />overall overseeing of the model. The 24-h precipitation accumulations estimated by the <br />model for selected observation sites will be automatically posted on the CSU Web site. <br /> <br />11-17 <br />
