The authors have addressed the referee comments.

The authors should consider the following:

P. 22

L. 8: I suggest replacing probably with likely.

P. 51+

Fig. captions: I suggest the authors indicate the end ranges of the colour scale wherever appropriate. For example, for Fig. 2, dark red relatively high values, yellow/white relatively low values.

P. 54+

Fig. captions: I suggest the authors indicate that the enclosed legends provide information on what each colour plotted represents.

P. 66

It seems more like purple shading than blue shading.
