Subject: | SGP/SONDE/C1 - Temperature/RH incorrect |
DataStreams: | sgplssondeC1.c1, sgpsondewnpnC1.b1 |
Description: | The temperature throughout this sounding is too high and as a result the RH values will be incorrect as well. I'm not sure what is wrong here but the operators noted reasonable values (18.1 degC, 87%) in the log before launch. Review of the raw data, however, shows the sonde reporting temperatures nearly 20 degC higher. I suppose it is possible that the operator entered into the log the reference temperature from the GC25 ground check set rather than the temperature reported by the sonde - I can't think of any other explanation - there is no doubt that the temperature sensor on this sonde was bad. |

Subject: | SGP/SONDE/C1 - Bad RH Data |
DataStreams: | sgpsondewnpnC1.b1 |
Description: | The RH values during this sounding oscillate between reasonable values and near-zero values. The oscillation is due to failure of the RH sensor heating process. |

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 - Soundings done as part of dual-sonde flights |
DataStreams: | sgpsondewnpnC1.b1 |
Description: | The following soundings done during the subject time period were flown in dual-sonde mode in which the standard ARM RS92 radiosonde was attached to the same balloon with a NASA ATR (atmospheric temperature reference) radiosonde. The radiosondes were separated by a 6' styrofoam bar. To accommodate the additional weight, we used 1200g balloons rather than 350g balloons. Accordingly, we want to alert users that these soundings may reach higher altitudes than normal for ARM soundings and that the ascent rate may be somewhat higher. The following soundings are affected: Sequence Date UTC launch time 1 2/22 0530 2 2/22 1730 3 2/22 2330 <---- No data: launch failure 4 2/23 0230 5 2/23 0530 6 2/23 1730 7 2/23 2030 8 2/23 2330 9 2/24 2330 10 2/25 0215 11 2/25 0509 12 2/25 1730 13 2/25 1930 14 2/25 2300 |

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. |
