Mapping and modelling urban growth and its impact on the hydrology of urban watersheds with satellite imagery

EarthzineJuly 9, 2013Earth Observation, Feature, Featured Article, In-Depth, Original, Water

Figure 3: Average daily rainfall (shaded and units of millimeters) from June-August (200-2006) composited for days with weak atmospheric forcing (lef). 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, 1995ÛÒ2003) on days dominated by weak atmospheric forcing (right) in Atlanta, Georgia. Image sources: [4] and [5], respectively.

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.

Key phrase trends in climate change research and communication

Figure showing database search results using CC as the key phrase. The annual counts for research articles and New York Times articles are displayed on the primary axis while annual counts for NSF grants are displayed on the secondary axis. The vertical lines denote years with notable climate change-related events.

Words are important. Using Û÷climate change’ instead of Û÷global warming,’ or vice versa, may not seem that major of a difference. But research shows there is a large gap between usage of the phrases and what is associated with each term.

It is widely known that the Earth system undergoes change due to human influence. However, how can one estimate the extent of change without an adequate knowledge of the actual pre-industrial atmospheric chemistry of the planet and, then, infer the differences?

Rita Colwell: Keeping Her Aim on Cholera

EarthzineNovember 28, 2012Feature, Featured Person, Health, In-Depth, Original, People, Sections, Water

When cholera killed hundreds living in coastal towns and epidemics were linked with sea travel, newspaper cartoons at the turn of the century depicted the disease as a ferocious sea monster poised to attack fishermen resting on the docks. Today, the disease is still a scourge that claims hundreds of thousands of lives in developing countries every year.
