| Subject: | Pressure jump at launch |
| DataStreams: | sgpsondewrpnB4.a0, sgpsondewrpnB4.a1 |
| Description: | The difference between the first pressure value reported by the sonde after launch (944.9) and the surface pressure (949.8) is larger than expected. The absolute altitude for the entire sounding and the ascent rate for the first 30 seconds will be questionable. |
