Foreign scientists first drawn by satellite to China air pollution map | | | air pollution air pollution air pollution from China _ news

People's daily January 20 hearing, according to the overseas Chinese network reported Friday, France and Belgium atmospheric scientists published in the journal geophysical research communications reveals that they mapped the surface contamination in North China from space for the first time.

Scientists use the infra-red detectors installed on the European Organisation for, draw over the North China plain in the January 2013 covers Beijing, Tianjin and Hebei flow diagram of particles of carbon dioxide, sulphur dioxide and ammonia.

France National Centre for space research (CNRS) said that scientists were surprised at the successful application of this technology, but the successful mapping requires two things.

First, the weather conditions must be "stable", this pollution can gather on the surface.

Second, to have larger temperature difference between the surface air and upper-air, to be able to show pollution heat radiation.

Reports that this technology may be an offer to help China deal with severe haze.

Reports also said that satellite surveillance pollution cloud conditions and powerful tool for predicting pollution cloud movement, to assist the authorities in a timely manner to alert residents and recommendations.

外国科学家首次用卫星绘制中国空气污染图|中国空气污染|空气污染|空气污染图_新闻资讯

　　人民网1月20日讯 据侨报网报道，周五，法国和比利时大气科学家在《地球物理研究通讯》杂志上发表文章指出，他们首次从太空绘制了中国北部的地面污染图。

　　科学家使用安装在欧洲气象卫星上的红外线探测器，在2013年1月绘制了华北平原上空覆盖北京、天津和河北的二氧化碳、二氧化硫以及氨气的粒子流动图。

　　法国国家太空研究中心(CNRS)说，科学家们对这项技术的成功应用感到惊讶，但是这项成功测绘需要两个条件。

　　首先，天气状况必须是“稳定的”，这样污染能聚集在地表。

　　其次，地表空气与高层空气之间要有较大温差，以便能够显现污染的热辐射。

　　报告说，这项技术可能会为中国对付严重的雾霾提供帮助。

　　报告还说，卫星可以成为监视污染云状况和预测污染云运动的有力工具，以帮助当局及时地向居民发出警报和建议。
