The air density correction to eddy flux measurements

  • E. P. Jones
  • S. D. Smith


Under the usual assumptions for the atmospheric surface layer, we show that air density fluctuations, particularly those due to temperature fluctuations associated with a heat flux, result in a small mean vertical wind velocity. Because of this, there can be a significant correction to eddy flux measurements of passive scalars, for example CO2, whose average concentration is very large compared to concentration fluctuations associated with the eddy flux.
