Flux Transects

The flux comparison tool is provided to assist the user in calibration mass flux or flow across a user defined line. From Model Control form, the Vertical Profile sub-tab contains the options that Define Calibration Series, View Plots and Calculate Error Statistics.  The user must first configure these comparisons with the Define Calibration Series option which is described below.

Flux Transects Comparisons Definition

The form used to configure the flux transects definitions is shown in Figure 1. This form provides the user with options of defining the number of time series to be compared in the # of Comps text box in the top left corner. The user should define an ID (usually a station name), and set the path to the predefined flux line as well as the data file corresponding to that flux line. Note that the key CTRL+H can be used to search and replace text in the case where the path to the data files is incorrect.

The following five columns are used to set the Parameter (based on the parameter codes shown in Figure 3). The Filter column is used to filter the data with a moving average. The Mult column is used as multiplier and Use will activate or deactivate for these comparisons by checking or unchecking the checkbox. Users can configure these definition settings by directly typing in the Flux Line Time Series Comparisons table in Figure 1 or RMC on the cells to obtain the Station Information form to set input options as shown in Figure 2.

Flux Transects Comparisons Plot

The following graphic shows the toolbar functions avaialbe when the user selects Plot . These functions are the same as time series calibration plot functions.

An example of Flux Transects Comparison plot is shown in Figure 4.
