The 5 mm contour is shown in blue and the yellow boxes represent the mean upwind (left box), city (center box), and downwind (right box) regions. Lightning flash anomalies (May to September, 1995‰ÛÒ2003) on days dominated by weak atmospheric forcing (right) in Atlanta, Georgia. Image sources: [4] and [5], respectively.

FIG4 A recently concluded research project called MAMUD investigated how high and moderate resolution satellite imagery can be used for mapping and modeling urban growth and its impact on the hydrology of the urban and suburban environment. The paper focuses on research methods, major findings, and work carried out on the Greater Dublin Area in Ireland.
