DataStreams: | twpsondeC2.00, twpsondewnpnC2.00, twpsondewnpnC2.a0, twpsondewnpnC2.a1 |
Description: | There were no sondes launced during this period because there was no helium on site and the hydrogen generator was not working. The hydrogen generator was repaired and launches resumed. |

Subject: | TWP/SONDE/C2 - Missing Winds |
DataStreams: | twpsondewnpnC2.a0, twpsondewnpnC2.a1 |
Description: | About half of the soundings in November-December exhibited drop-outs in the winds. These dropouts were typically over a depth of 1-2 km. Sometimes the dropout occurred at the surface, sometimes at the top of the sounding and sometimes in the middle. These gaps occurred on: 19981126 19981129 19981206 19981209 19981210 19981211 19981212 19981221 19981222 |

Subject: | TWP/C2 Installation |
DataStreams: | twpsondewnpnC2.00, twpsondewnpnC2.a0, twpsondewnpnC2.a1 |
Description: | The Nauru ARCS was installed during the period September-November 1998. Data were being collected by the end of October, but for the first several weeks of November, the site was undergoing considerable change, so data from that period should be used with caution. The official site dedication occured on November 20. Most on-site activity ended following the dedication so we will consider November 20 to be the beginning of the Nauru operations. The last members of the installation team left Nauru on November 24. |

Subject: | TWP/SONDE/C2 - Bad RH Data (AIRS Validation Sonde) |
DataStreams: | twpsondewnpnC2.a1, twpsondewnpnC2.b1 |
Description: | The RH sensor heating circuit failed on this sonde. This results in oscillation of reported RH between reasonable values and values near zero. This was an AIRS validation sounding. |

Subject: | TWP/SONDE/C2 - Failure of RH sensor |
DataStreams: | twpsondewnpnC2.a1, twpsondewnpnC2.b1 |
Description: | It appears that the RH sensor heating circuit failed during this sounding. The RH oscillates rapidly between low (~0 %RH) and not so low (ambient %RH) and the oscillation seems to stop when the temperature is below ~35 degC. According to Vaisala these are symptoms of failure in the ASIC (application specific integrated circuit) that controls the heating. |
