A Comparison of Three Gap Filling Techniques for Eddy Covariance Net Carbon Fluxes in Short Vegetation Ecosystems

Figure 6

Two-dimensional plots illustrating mean absolute error (MAE) in gap-filled NEE, expressed as MAE, varied as a function of day of year ( axis) and gap length ( axis). Plots in row were shown for marsh, rice, and soybean sites, and plots in column were shown for MDV, LUT, and NLR methods. The different size and color of the circle refer to magnitude of MAE, and unit is mgCO₂ m⁻² s⁻¹.
