Acknowledgment: This project took advantage of netCDF software developed by UCAR/Unidata (www.unidata.ucar.edu/software/netcdf/).

Short Description of Functionality

The application taylordiagram allows to visualize the quantities that describe the model performance calculated by NCDELTA as a Taylor-Diagram and to list them as a table.

In the Taylor-Diagram standard deviation, correlation as well as pattern root mean square error (PRMSE) between model and observation are graphically displayed.

Figure GUI of the application taylordiagram.

Input-Files

  1. NCDELTA-Output files format (cf-netcdf.nc).

Output-Files

  1. (optional) Taylor-Diagram as bitmap (*.JPG,*.PNG), as a vector graphic (*.PDF,*.EPS) or as a MATLAB figure file (*.FIG).
  2. (optional) Table of the model performance quantities (*.CSV,*.DAT)

Methodology

Visualization of the model performance in a Taylor-Diagram after Taylor (2001).
The table lists

  • Root Mean Square Error (RMSE)
  • Taylor Skill 4 (Equation 4 in Taylor (2001))
  • Taylor Skill 5 (Equation 5 in Taylor (2001))
  • Pattern Root Mean Square Error (PRMS)
  • Bias (Difference of the Means)
  • Means of the respective model quantity and observational quantity
  • Standard deviations of the respective model quantity and observational quantity
  • Correlation between the respective model quantity and observational quantity
  • Positional attributes of the quantity (GK-Coordinates, latitude and longitude, depth, position name) compared by NCDELTA
  • Filename of the NCDELTA-Output file
  • Number of data points used for the comparison
