Student Plotting Exercise

This directory contains a set of data which can be used by students to plot a standard surface map for analysis. A blank basemap showing selected station identifiers with cloud cover symbol location is provided. Decoded surface observations in text format for first order stations are provided.

  • basemap (8.5x11" postscript)
  • basemap (11x17" postscript)
  • basemap (gif format)
  • Surface parameter text file for 12Z Nov 10, 1998
