DataStreams: | sgpsondeC1.00, sgpsondewnpnC1.00, sgpsondewnpnC1.a1, sgpsondewnpnC1.b1 |
Description: | It looks as though the temperature sensor was damaged on launch. The recorded temp goes from 16.4 at the surface to -42.6 at 2 seconds into the flight. The temperature never exceeds -42 though the RH and pressure look reasonable, but probably should be considered questionable. |

The temperature series is 9.9, 10.8, 11.3, 1.5, 11.6, 11.6, 11.6, -32.2 and remains below -30 degC. I don't know why this occurred, but it clearly is incorrect. The pressure data looks OK as does the RH, though the RH data are missing (probably sensor failure) above roughly 3.5 km. |

Subject: | SGP/SONDE/C1 - Incorrect Surface Pressure |
DataStreams: | sgpsondewnpnC1.a1, sgpsondewnpnC1.b1 |
Description: | It appears that the operator made a typographical error when entering the surface pressure. The file has 987.0 hPa and it probably should be 978.0 which would be consistent with the first sample provided by the radiosonde (977.3 hPa), the surface pressures recorded for the adjacent soundings, and the THWAPS pressure. Because the sounding altitude is calculated assuming the surface pressure is correct, the altitude values for the entire flight and the ascent rate values for the first 30 seconds of the sounding will be incorrect. |

DataStreams: | sgpsondewnpnC1.a1, sgpsondewnpnC1.b1 |
Description: | The RH data in this sounding is erratic between 2km and 10 km, oscillating between reasonable values (~40%RH) and zero. I certainly doubt that this is a real, heretofore unreported, atmospheric phenomenon so I have to conclude that something is probably wrong with the sensor. I have not seen this behavior before. One would have to look at the absolutely raw RH data to explore further. |

DataStreams: | sgpsondewnpnC1.a1, sgpsondewnpnC1.b1 |
Description: | The RH samples in this sounding oscillate between reasonable values (60-80%) and zero. This may be a problem with the RH sensor or the software that alternates between the heated and non-heated RH elements. In either case, the reported values are questionable. More investigation of the raw binary data would be required to diagnose further. |

Description: | The RH values during the first 15 minutes of this sounding oscillate between reasonable values and near-zero values.

Subject: | SGP/SONDE/C1 - A few bad temperature values at the beginning of the sounding |
DataStreams: | sgpsondewnpnC1.a1, sgpsondewnpnC1.b1 |
Description: | I've never seen this before. The temperature reported by the radiosonde dropped over 30 degC just after launch (usually a symptom of a broken temperature sensor), but then recovered after 14 seconds of bad readings. The temperatures from 2 seconds through 14 seconds after launch are incorrect, the remainder of the sounding looks fine. I have sent the data files to Vaisala for their consideration. |

DataStreams: | sgpsondewnpnC1.b1 |
Description: | The RH values during the first half of this sounding oscillate between reasonable values and near-zero values. The oscillation is irregular and seems to be related to failure of the RH sensor heating process. |

Subject: | SGP/SONDE/C1 - Surface pressure incorrect |
DataStreams: | sgpsondewnpnC1.b1 |
Description: | I think the operator inadvdertently transposed to digits when entering the surface pressure value. The value entered is 987.0 hPa but the value shown in the raw data file at launch is 978.0. 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. |

DataStreams: | sgpsondewnpnC1.b1 |
Description: | The operator entered a the surface temperature incorrectly on this sounding. The sonde data file shows the temperature as 33.5 degC but the operations log shows it as 3.5 degC. The first temperature recorded by the sonde after launch is 3.7 degC, consistent with the typical early morning inversion. |

Subject: | SGP/SONDE/C1 - DigiCORAIII failed, replaced with S01/S02 launches |
DataStreams: | sgpsondeC1.00, sgpsondewnpnC1.b1 |
Description: | The digiCORA-III failed on Saturday 2004-01-17. The operators reported that they were unable to load the software and conduct normal soundings. Following procedure, they conducted the regular soundings by using the S01/S02 systems as allowed by the AIRS IOP schedule. The netCDF header fields "input_source" and "facility_id" will mention which of the S01/S02 systems was used in these launches. |
