| Subject: | SGP/SONDE Pressure jump at launch |
| DataStreams: | sgpsondewrpnB4.00, sgpsondewrpnB4.a0, sgpsondewrpnB4.a1 |
| Description: | Sonde pressure before launch was 947.7, first sample after launch had pressure value of 940.8. THWAPS read 946.6. Either pressure sensor was jarred or the system failed to detect launch properly. Absolute altitudes for this sounding will be incorrect as will the ascent rate during the first 30 seconds of flight. |
