| 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. |

| Subject: | SGP/SONDE/C1 - Sonde RH values incorrect |
| DataStreams: | sgpsondewnpnC1.b1 |
| Description: | RH values for all sondes launched during this time were incorrect due to a faulty Ground Check set which damaged or conditioned the RH sensor improperly. |

| Subject: | SGP/SONDE/C1 - Increased precision for alt, dp, pres, rh, tdry |
| DataStreams: | sgpsondewnpnC1.b1 |
| Description: | The output precision of the following variables was increased 20060928 alt changed from 1m to 0.1m dp changed from 0.1degC to 0.01degC pres changed from 0.1 hPa to 0.01 hPa RH changed from 1%RH to 0.01%RH tdry changed from .1degC to 0.01degC Note that the increase in precision does not necessarily imply an increase in accuracy. Users are cautioned to continue to use their best scientific judgement when using these or any other data. |
