| Subject: | SGP/SONDE/C1 - Surface pressure incorrect |
| DataStreams: | sgpsondewnpnC1.b1 |
| Description: | I think the operator inadvdertently entered an incorrect surface pressure value. The value entered is 988.8 hPa but the value shown in the raw data file at launch is 968.8. As a result, the absolute altitudes in this sounding will be slightly incorrect as will be the ascent rate during the first 30 seconds of flight. |
| Suggestions: | Recalculate altitudes from corrected pressure at surface. |
