Subject: | Bad pressure values CF sounding 970704:0525 |
DataStreams: | sgpsondewrpnC1.a1 |
Description: | The pressure values and hence altitude values are most likely incorrect in this sounding. It also appears that an incorrect surface pressure value was entered by the operator. The surface pressure value in the data (986.8) is somewhat higher than the surface pressures for the neighboring soundings and higher than recorded in the raw data collected before launch (~978 hPa). The first pressure value recorded by the sonde after launch is 884.8 hPa. Analysis of the absolutely raw data reveals that the sonde was reading about 978 hPa well before launch, then suddenly dropped to 886.8 at which it remained stable for several minutes, then began slowly decreasing as would be expected after launch. My best guess is that the sonde was somehow damaged during handling before launch resulting in erroneous pressure values. Relative pressure changes from an 'apparent' surface value of 886.8 hPa may be correct, but the absolute pressure values are not. |

Description: | The difference between the first pressure value recorded by the radiosonde after launch (984.5) that the surface value entered by the operator (989.3) is somewhat larger than would normally be expected. This will result in incorrect altitude values throughout the sounding. The ascent rates during the first 30 seconds also will be incorrect. |

Description: | Radiosondes manufactured at Vaisala's Woburn, MA factory during the first of January 1998 have incorrect serial numbers. Instead of being numbered 8012XXXXX these sondes are numbered 7012XXXXX. Vaisala has been informed of this, has confirmed the problem, and has corrected their numbering for all subsequent sondes. 163 incorrectly numbered sondes were shipped to ARM on 1/9/98. Some have been used at the CF since 1/19/98:1430. |

Description: | The difference between the sonde-reported pressure at the surface (969.1 hPa) and the first pressure value reported after launch (963.5) is larger than expected. This may indicate that either the pressure sensor was jarred at launch, that the system failed to correctly identify the launch start time, or some other problem. The ascent rates during the first 30 seconds of the sounding will be incorrect as will the absolute altitudes during the sounding. |
