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.
Measurements:nim30ecorM1.b1:
  • Corrected sensible heat flux(h)
  • CO2 flux(fc)
  • Latent heat flux(lv_e)
  • friction velocity(ustar)

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.

  • covariance uc(cvar_uc)
  • rotated covariance wc(cvar_rot_wc)
