Figure 4

Scatter plot of the coefficient of variation of monthly river discharge (CV) vs. the monthly particle backscattering spectral slope (η). Both variables are dimensionless (see text). The standard deviation of monthly η is also indicated as vertical bars; dot diameter is proportional to the number of cloud-free satellite images. The best linear fit (y = −0.186 x -1.143; r2 = 0.35) is meant to highlight the general trend that marks the relation between flow erraticity (CV) and GSD. Months with less than three valid observations were discarded, as calculation of a standard deviation is not possible for them. Colorbar indicates months for each point (month numbers are also reported); reddish dots represents late fall/early winter months. Plot generated by using MATLAB 7.1 http://uk.mathworks.com/products/matlab.
