中印看来是两个难兄难弟,两个备受洪水肆虐的文明古国。不过,今年的洪水季,印度恒河的洪水看上去要来得更猛烈些,这场景才更叫看海模式吧!如下图2015年8月与2016年8月的对比动图【NASA原文点这里】:

In August 2016, heavy monsoon rains pushed the Ganges and other rivers in eastern and central India to the breaking point.These images use a combination of infrared and visible light to increase contrast between water and land. Water is blue. Vegetation is green. Notice that the water is a slightly lighter shade of blue in the lower image due to all the suspended sediment in the water.

以上是一组对比今年3月27日和7月28日长江中游沿岸以及洞庭、鄱阳两大湖水位变化的动图。如果两大湖春季的水位更接近正常的话,恐怕今年汛期的洪灾将更加惨烈。今年的洪灾已经造成了220亿美元的损失,也成为仅次于1998年洪灾的中国第二大最具破坏性的天气灾害事件,也是1980年有记录以来全球(美国以外)第五大最具破坏性的自然灾害事件(下图)。【NASA原文点这里

NO2 & Air Pollution Tracking by NASA

空气污染和二氧化氮的监测及趋势(2005 – 2014)

美国宇航局过去十年对全球195个城市的空气污染监测发现,欧美日本等地空气质量有所改善,但中国、印度及中东空气污染面积有所扩大。这里被监测的污染物是二氧化氮,主要来自汽车尾气、发电厂及工业活动的排放。二氧化氮可以很快变成地面层臭氧,是城市中雾霾的主要成分之一。如下图,中国的二氧化氮高浓度覆盖面积扩大最为明显(红色为浓度5000万亿分子/立方厘米):【点这里阅读英文原文

Case Study: Air Pollution Visualized, Daily

It all started in the lead up to the Olympic Games in 2008, I had a tickling idea to start paying attention to Beijing’s air pollution (video I co-produced). So I asked a friend whose apartment window has an open view over the skyline. I asked a favor to take a picture a day, if possible. And that project kept going for more than eight years. If you haven’t been to China, or smelled the lung-penetrating air or coughed it out while there, you have no idea how bad the air quality is. But just look at this below, one view from the exactly same angle but on two days.

Two days in Beijing with air quality between night and day [Pity that the scent cannot be reproduced here]

Case Study: Sliding Onto The New York Times

When my colleagues and I at Asia Society invited The New York Times columnist Nicholas Kristof to our glacier exhibition, we aimed at nothing less than wowing him and other viewers every way imaginable, from the 30-foot wall-to-wall photo prints to our century-spanning multimedia portfolio, armored with cutting-edge digital techniques.

Above is a slider tool I came up as a concept to illustrate the dramatic glacial change in a compelling way and add an intuitive dose of interactivity, inviting the viewer to slide across the image frame to travel between past and present (and tap on a smartphone or tablet nowadays). The Times staff loved it and put it right on top of Kristof’s column.
