Subject: | AWR/LDIS/MET/S1 - Precipitation Measurements Suspect |
DataStreams: | awrmetS1.b1 |
Description: | Analysis of the PARS2 and the PWD precipitation data indicate that the results are suspect, possibly due to frost/blowing snow. Both instruments reported precipitation for a majority of the days. The TSI movies were reviewed and the days of noticeable precipitation are: 12/26/15 12/31/15 - Potentially just frost buildup 1/6/16 1/11/16 1/12/16 1/13/16 |

Subject: | AWR/CPC/M1 - Failed pump |
DataStreams: | awraoscpcfM1.a1, awraoscpcfM1.b1 |
Description: | The pumps that draw air into the instrument for particles to be counted failed. The values reported by the instrument are not representative of the particle number concentration in the atmosphere |

Subject: | AWR/CPC/M1 - Instrument Startup, No Data Collected |
DataStreams: | awraoscpcfM1.a1 |
Description: | At the instrument startup of the AMF2 deployment, the computers were turned on before the instruments were turned on. The data collection starts automatically on instrument startup, but if the instruments are not on and connected, the data text files will contain missing data codes such as NaN or -9999. |

Subject: | AWR/CPC/M1 - CPC Flooding |
DataStreams: | awraoscpcfM1.b1, awraoscpcfM1.a1 |
Description: | Following a routine flow rate check, the CPC showed signs of flooding with the orifice pressure dropping below 10 kPa. The butanol fill bottle was removed from the system. After two days of continuous running the system dried out and the orifice pressures were restored to nominal values. The data from this period is suspect. |
