| Subject: | Pressure jump at launch |
| DataStreams: | sgpsondewrpnB4.a0, sgpsondewrpnB4.a1 |
| Description: | The first pressure value reported by the sonde after launch (939.1) is much lower than that reported at the surface (946.1). This may result from jarring at launch, failure of the system to detect launch, or other problem. The absolute altitude for this sounding and ascent rates for the first 30 seconds will be incorrect. |
