| Subject: | Pressure jump at launch |
| DataStreams: | sgpsondewrpnB4.a0, sgpsondewrpnB4.a1 |
| Description: | The first pressure value reported by the sonde (941.7) is much smaller than the surface value (949.9) indicating that the sonde was either jarred on launch, or that the system failed to properly identify the start time. The absolute altitude for the sounding and ascent rates for the first 30 seconds will be incorrect. |
