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. |

Subject: | NSA/MET/C1 - Temp/RH/wind data questionable |
DataStreams: | nsametC1.b1, nsatwrC1.b1 |
Description: | New wind sensors and new T/RH probes were being installed during this time period. The tower booms were lowered and much of the data collected were not at listed heights nor were the data accurate due to configurations during install. |

Subject: | NSA/MET/C1 - Wind data intermittent |
DataStreams: | nsametC1.b1, nsatwrC1.b1 |
Description: | There was a loose wire on the serial data multiplexer causing the wind data to become missing during high wind situations. The high winds caused the enclosure to vibrate making the connection intermittent. |
