This suggests that the aerosols present in layer 3 may have a higher concentration or different characteristics compared to other layers at the arrival altitude of 200 m. The higher WCWT values indicate a stronger correlation between the wavelet coefficients at different scales and locations within this layer, which could be indicative of a more homogeneous aerosol distribution.
However, it is important to note that this conclusion is based on the analysis of only one dataset and further studies would be needed to confirm these findings. Additionally, it is possible that other factors such as wind patterns or meteorological conditions could also influence the distribution of aerosols at this altitude.
