To curb China’s haze and air pollution, water cities’ atmosphere for half hour daily like a garden

subtitle: A new air pollution-control geoengineering measure inspired by watering a garden

A new idea to cut back on air pollution: spray water into the atmosphere from sprinklers atop tall buildings and towers, similar to watering a garden. This suggestion comes from Prof. Shaocai Yu of Zhejiang University in China, and North Carolina State University in the US. In an article published in Springer’s journal Environmental Chemistry Letters(Yu, ECL,DOI 10.1007/s10311-013-0444-0), Prof. Yu suggests this course of action as a novel approach to help curb the severe air pollution and heavy haze that is experienced in many Chinese cities, as well as others around the world. Prof. Yu proposes spraying water into the atmosphere to simulate natural types of precipitation that are able to most effectively scavenge or collect and remove aerosol and gaseous pollutants. Because water that is used for these purposes could be collected and reused, adopting this kind of plan would not exacerbate existing water shortages. This geoengineering scheme could help to reduce the fine particle load in the atmosphere efficiently to a safer level of 35micrograms per cubic meter. And it could be done in a short time, depending how the water is sprayed. This geoengineering technique is very natural, technologically feasible, efficient and low cost. All the necessary technologies and materials required to make it work are already available, from high buildings, towers and aircraft, to weather modification technology and automatic sprinkler heads. Research and experiments are currently underway to design a suitable water-delivery systemto successfully implement this geoengineering option. Prof. Yu plans on puttingthe experiment to the test in Zhejiang University campus and then Hangzhou, the city where Zhejiang University is located.

The Springer had a Press Release for this paper in English, Chinese and German (http://www.springer.com/about+springer/media/springer+select?SGWID=0-11001-6-1450943-0). After the publication of this paper, more than 400 world medias, newspapers, and TVs have widely reported the results and methodfor this paper such as sciencedaily, sciencecodex,natureworldnews, pbs, IBtimes, CNN, yahoo, Wall Street Journal, mashable.com,phys.org, usa.chinadaily, Hongkong Herald, SouthChina Morning Post, China Meteorological Administration (CMA) and ChineseAcademy of Science, eastday, sina, Shanghai people's Broadcasting Station etc listed as follows:

Figure 1.Conceptual pictures of the geoengineering scheme by spraying water into the atmosphere like watering gardens to scavenge air pollution at the top of high buildings and towers (like (a) CCTV building and (b) Shanghai DongfangTower) and square (like (c)Tiananmensquare). The background is haze pollution in Beijing in January of 2013 based on the pictures from (http://www.theatlantic.com/infocus/2013/01/chinas-toxic-sky/100449/). An example for spraying water into the atmosphere at the top of U.S. Embassy Beijing building to scavenge airpollution is shown in (d).

Figure 1A. Conceptual figure about how the water sprayed can be collected on the ground and reused for the future spray.

Figure 1B. Conceptual figure about how the water is sprayed from the top of the buildings. There is not need to install giant sprinklers on the top of the buildings but regular ones, depending on real situation.
