Hi Dennis,

thanks for the information found in RAOB. But what Im trying is different: I mean the original WMO soundings, (UWYO calls then *.raw). Im looking for an existing procedure to decode WMO soundings and then plot it with the mentioned NCL script. Attached I send an example of a raw sounding file.

Thanks in advance,

Luis

I found the following:

     http://www.raob.com/assets/downloads/rawformat.pdf

You can read an entire file (one sounding per file) as a 'string'

   raw = asciiread("raw_sounding", -1, "string")

then use the str* and "tofloat" to extract the information.

Good luck
