| Subject: | Pressure jump after launch |
| DataStreams: | sgpsondeB1.a1 |
| Description: | The first pressure value recorded by the sonde after launch (945.6 hPa) is considerably lower than the surface value (963.3). This implies that either the pressure sensor was jarred at launch or that the system mis-identified the start time for the sounding. In either event, the ascent rate during the first thirty seconds and all altitude values are suspect. |
