Outline

Outline

  • Plot and analyze a hodograph

  • Create a precipitable water chart

  • Tell you where to get the tools


Hodograph

Hodograph

  • Get data – http://raob.fsl.noaa.gov; or radiosonde database on CD-ROMs

  • Run C program – hodo.c

    • Need UNIX/Linux

  • Plot in spreadsheet – Excel graph

    • Customize, analyze, print, save image

Precipitable water

Precipitable water

  • Get data – http://raob.fsl.noaa.gov; or radiosonde database on CD-ROMs

  • Run C program – pw.c

  • Plot in spreadsheet – Excel graph

    • Customize, analyze, print, save image

May have to concatenate several files; put 999 at end


Precipitable water pw c

Precipitable water – pw.c

  • Compile this program just like hodo.c

    • See comments within program


Precipitable water excel spreadsheet

Where do i get this

Where do I get this?

  • http://www.crh.noaa.gov/unr/?n=scm

  • convectM.c

    • Computes multiple sounding variables


Wrap up

Wrap-up

  • These programs provide opportunity for nice graphics and climatological studies

  • Garbage input soundings = garbage output variables

  • I don’t provide “official” support

  • New variables don’t get added quickly
