Subject: | NIM/MWR/M1 - Instrument noise problem/RF interference |
DataStreams: | nimmwrM1.00, nimmwrlosM1.b1, nimmwrtipM1.a1 |
Description: | Data are affected by intermittent spikes that become more frequent starting in March 2006. Spikes affect data mostly around 9 AM and 18:00 PM. The origin of the spikes is probably RF interference. |

Subject: | NIM/ECOR/M1 - Data Suspect for NW and East Wind Directions |
DataStreams: | nim30ecorM1.b1 |
Description: | Data for these wind directions must be closely evaluated to determine if it is correct or incorrect. Problem will remain for the entire extend of the NIM deployment. |

Subject: | NIM/MWR/M1 - Reprocessed: Recalibration to correct for occasional overheating. |
DataStreams: | nimmwrlosM1.b1, nimmwrtipM1.a1 |
Description: | The radiometer was intermittently thermally unstable resulting in poor calibrations for four brief time periods. These data have been reprocessed to apply corrected calibrations. The affected time periods were: 20060302-20060303 20060423-20060425 20060512-20060515 20060531-20060603 |

Subject: | NIM/ECOR/M1 - Effects on ECOR CO2 Flux and Concentration By Aircraft |
DataStreams: | nim30ecorM1.b1 |
Description: | Aircraft landings, departures, and running aircraft on the airport pad were found to produce large spikes in the half hourly CO2 flux and small spikes in CO2 concentration on many days during the entire deployment of the AMF at NIM. This influence was found on 40% of the days in March and April 2006 and sometimes for multiple periods in a day; this was typical of the year of data. The spikes range from only several micromoles s-1 m-2 to one hundred or more for flux (a typical spike was in the twenties) and near zero to 1.0 mmoles m-3 for CO2 concentration (typically around 0.15). The aircraft influence was caused by persistent easterly winds; the airport terminal pad and the nearest part of the runway were almost directly to the east of the ECOR location. Occasionally an influence on water vapor density was detected, but this was fairly rare and usually of very small magnitude. |
