Sample MET Analysis Scripts

This page provides sample scripts that may be run on MET output files to analyze, summarize, and/or plot the data. Feel free to modify these sample scripts to perform the type of analysis you need.

Users are strongly encouraged to submit their own analysis scripts via met_help@ucar.edu to be posted on this page.

R Scripts

R is an extremely powerful statistical analysis and graphics package freely available for many platforms.

• The mode_summary.R script may be run to summarize the object statistics files from one or more MODE runs. The script keeps running sums of the counts and areas for the matched/unmatched forecast/observation objects. For each simple object identified, the script records its maximum interest value. It then dumps out the median value of those maximum interest values found.
  This sample output summarizes a single MODE run.
• The mode_quilt_plot.R script may be run to generate a quilt plot summarizing MODE output for several scales. A quilt plot may be generated when a single case is run using a variety of choices of convolution radii and thresholds. A quilt plot is an image where each box represents a summary measure of MODE for a given choice of radius and threshold.
  The quilt plots shown in this sample PDF file were generated by running the same case through MODE applying combinations of 29 different convolution radii and 30 different convolution thresholds.
