Subject: | NSA/SONDE/C1 - Increased precision for alt, dp, pres, rh, tdry |
DataStreams: | nsasondewnpnC1.b1 |
Description: | The output precision of the following variables was increased 20060929: 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 - CMH offline |
DataStreams: | nsametC1.b1 |
Description: | Beginning 1/24/2011, the CMH went offline resulting in missing temperature and dewpoint measurements and erroneous vapor pressure, saturation vapor pressure, and RH measurements. Problem fixed with a power cycle. |

Subject: | NSA/MET/C1 - Instrument problem |
DataStreams: | nsametC1.00, nsametC1.b1 |
Description: | The CMH is showing signs of problems. The cmh_dew_point and chm_temp are continuously set to missing data. cmh_rh, cmh_sat_vapor_pressure and cmh_vapor_pressure are flatlined. Mike, do you have a suggestion for repair? |
