Subject: | NIM/ECOR/M1 - Flux Data Suspect for Some Wind Directions |
DataStreams: | nim30ecorM1.b1 |
Description: | NIM: For some wind directions the horizontal fetch was not representative of the field in which the AMF was located. Therefore, for the wind direction ranges 90-170 (buildings) and 220-280 (trees) degrees, the fluxes are affected by insufficient fetch and surfaces, buildings, or vegetation that are not similar to the local field conditions. |

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. |

Subject: | NIM/RWP/M1 - Reprocess: Wind direction offset |
DataStreams: | nim915rwpwindconM1.a1 |
Description: | A strong wind storm on June 17, 2006 toppled the RWP antenna. After repair and reinstallation, the wind direction reported by the instrument was rotated counterclockwise 90 degrees, possibly because the antenna was installed rotated by 90 deg. This condition continued through the remainder of deployment. All wind direction values need to be increased by 90 degrees. |
