 Dear Dennis,Thank you so much for your nice reply.The software related to the brand of radiosonde, save sounded data in TEMP format. I found below link showing an example of TEMP data for OIII/40754/Tehran-Mehrabad (Iran) station.Display sond

If I remember correctly, TTAA and TTCC are related to mandatory levels data (1000, 925, 850, 700, 500, 400, 300, 250, 200, 150, 100 mb), and TTBB and TTDD are related to significant levels data (70, 50, 30, 20, 10 mb). Sounded data (temperature, wind and humidity) for each level are coded in these files. I'm not much familiar with these codes, however, each TTXX (TTAA, ..., TTDD) has different sections. For example one section starts with 99, another one starts with 88, ..., 44. Also 31313, 41414, 51515 are related to different sections.However, TEMP format is a standard format, like synop ( SYNOP - Wikipedia),

to report observed data in GTS (Global Telecommunication System).Pardon me for any ambiguity in my sentences.

 re: "decode TEMP data"
This is VERY ambiguous.
Well what format is it?  Text?  Some meteorological code?

Hope you are doing well.I would like to decode TEMP data (sounding data), then plot skew-t. I found https://www.ncl.ucar.edu/Applications/Scripts/skewt_2.ncl, but what about decoding TEMP data. It could be a PyNGL or python script.I'll be thankful for any help.
