HYSPLIT Forum: hysplitbbs.arl.noaa.gov

Hi All,
I have tried to convert the cdump to ascii using to ways
(1) Hyspliyt GUI :
I had selected the following options (as shown in the attached picture ) on GUI window while converting cdump to Ascii format. The cdump.txt file which get created had file size of (290MB).

(2) When I use the following command (./con2asc -scmtv cdump) from the Unix terminal; the cdump.txt file created have size of 3.5MB.

I don't understand why there is such a huge difference between the sizes ?

I would like to create the file of same size as Hysplit GUI.

Could you please help me to resolve this issue ?

Thank You,

You are forgetting the additional dashes in the command line.

Looking at the conc_asc.tcl script in the guicode subdirectory, using the switches you set in the GUI should run the following command:

con2asc.exe -i./cdump -s -m -z -x -u1.0 -U1.0

Try this on the UNIX side. Note however, by turning on the "zeroes" you are making a much larger file.
