Comparison Between Eddy‐Covariance and Flux‐Gradient Size‐Resolved Dust Fluxes During Wind Erosion Events

Estimating accurately dust emission flux during aeolian erosion events is crucial for quantifying the amount of in atmosphere. The rare existing field experiments such were mainly performed using flux-gradient (FG) method. Here, we present first intercomparison size-resolved fluxes estimated by both FG and eddy-covariance (EC) methods several events. Both applied simultaneously WIND-O-V (WIND erOsion presence sparse Vegetation)'s 2017 experiment over an isolated erodible bare plot South Tunisia. Overall, predict similar particle smaller than about 4 μm. For coarser particles, EC method predicts a Factors explaining this difference are discussed as different sampling heads used counters methods, or possible weakening constant layer at location upper counter This highlights difficulties advantages each well their complementarity.
