Short summary

We conducted an extensive observational analysis involving 10 dust storms to assess the electrical properties of dust particles. Using wavelet coherence analysis, we found that the space charge density and dust concentration were highly correlated over 10 min timescales. The significant linear relationship between space charge density and dust concentration at given ambient conditions suggests that the mean charge-to-mass ratio of dust particles was expected to remain constant.
