Subject: | SGP/SONDE/C1 - Surface pressure incorrect |
DataStreams: | sgpsondewnpnC1.b1 |
Description: | I think the operator inadvdertently typed an 89 instead of a 78 when entering the surface pressure value. The value entered is 989.9 hPa but the value shown in the raw data file at launch is 978.9. 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 - Surface pressure incorrect |
DataStreams: | sgpsondewnpnC1.b1 |
Description: | I think the operator inadvdertently mistyped a digit when entering the surface pressure value. The value entered is 975.6 hPa but the value shown in the raw data file at launch is 972.6. 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 - Mixed use of RS92-SGP and RS92-KL radiosondes |
DataStreams: | sgpsondewnpnC1.b1 |
Description: | Because of a manufacturer's production problem, we will be using both RS92-SGP (GPS windfinding and RS92-KL (Loran windfinding) radiosondes at the SGP/CF starting February 10, 2006. The radiosonde type used for the each sounding may be determined by looking the metadata variable "launch_status" in the netCDF data files. |

Subject: | SGP/SONDE/C1 - No Wind/Lat/Lon Data in Sonde Files |
DataStreams: | sgpsondewnpnC1.b1 |
Description: | The wind finding hardware failed so that no wind or latitude/longitude data was collected on the launches for these days. |

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. |
