~ ~l <br />Task 140 - TSTooI Enhancements <br />Objective: <br />Enhance TSTooI to support SPDSS modeling activities. <br />Background: <br />TSTooI and StateDMI are the primary da1;a processing tools used to prepare data sets for <br />StateCU and StateMod. Whereas StateDMI focuses on specific model data files, TSTooI <br />focuses on time series data in general, writing to StateMod file formats as the last step in <br />processing. TSTooI has been. in place for several years and the enhancements that are <br />identified here address specific needs. <br />Approach: <br />140.1 Implement Mixed Station Model Features. Implement 100% of the required <br />features of the Mixed Station Model, specifically: <br />• Enhance the f i 11Regre s s i on () command to allow multiple independent <br />stations for a single independent station and include parameters to indicate <br />when to use the best fit or specific stations, for combinations of months, <br />annual data, and linear/log transformation. <br />• Provide a general tool to analy;~e multiple stations, in order to indicate the best <br />combination of stations and pa~~ameters, for use with the above command <br />where specific stations are to bye indicated. <br />• Provide a command or tool to fill StateMod baseflow time series, using an <br />automated approach, to streamline data filling. This tool will offer the <br />features of the previous items. <br />• Streamline creation of filled data in new time series to simplify the filling <br />process. For example, make the newTimeSeries O command easier to <br />use and allow filled data to be automatically transferred to the new time series. <br />• Streamline creation of a residual graph comparing predicted value minus <br />observed value. <br />• In the regression results, list an annual RMSE for monthly regressions, which <br />can then be compared against the annual RMSE when monthly regressions are <br />not performed. <br />• Add the ability to create a time series and graph of the filled data <br />• Implement a tool to compute the wet/dry/average characteristics of time <br />series. This input is then used with the existing f i 11 Pa t t e rn () command. <br />Command parameters will be available to control the thresholds used to <br />determine wet, dry, and average conditions. <br />Communications and/or meetings will be held with State of Colorado staff, <br />Leonard Rice staff, and, if necessary the author of the Mixed Station Model, in <br />9 <br />
