Header sectionSonde # 991515151 1754 UTC 13 Sep 99 The first field is sonde identification serial number followed by the time of launch (HHMM format) in Universal Time Code (UTC) and the date (day month year). This is a special HRD header in the transmitted message file for each sonde released, inserted by the Editsonde software. It is a non-standard WMO/NWS format line that is stripped before it is received by the National Weather Service Telecommunication Gateway (NWSTG).
