Satellite Remote Sensing Big Data Accurate Monitoring of Air Data_Data Analyst Exam
With the increasing severity of the haze problem, air pollution has become the most pressing issue in Chinese society. To solve the air pollution problem, accurate monitoring of air quality and analyzing the source of pollution is the first step.
Beginning in 2013, the Ministry of Environmental Protection began to analyze the sources of air pollution, and has now completed the analysis of pollution sources in nine cities, including Beijing, Shanghai, Tianjin, and Nanjing. 2014, the nation's 338 prefectural-level cities, 1,436 monitoring sites of the six indicators of the passing of the monitoring data and the air quality index information has been released to the community.
However, the biggest problem with domestic air quality monitoring at present is that the data mainly comes from ground monitoring stations. This not only requires a large investment in station deployment, but also fails to enable forecasting and tracking of pollution sources, not to mention the accuracy of air data to specific neighborhoods. In Beijing, for example, there are currently 35 ground-level air quality monitoring stations, but they do not accurately reflect the entire Beijing air quality situation.
This gap in demand is the direction of Qingkong Technology, whose goal is to use "big air data to defend China's blue sky. To put it simply, Qingkong Technology uses an air quality data engine developed by NASA scientists to conduct high-precision air quality monitoring and pollution source analysis tracking based on satellite remote sensing technology, utilizing free resources such as satellite cloud maps and ground monitoring data.
Compared with the existing means of air monitoring and related startups, the advantage of Qingkong Technology is that they provide the engine software service of big data analysis, and does not require investment in hardware and equipment, the forecast can reach a high degree of accuracy of 1 square kilometer on the ground, and can also be reversed to the source of pollution.
For example, with Qingkong Technology's big data analysis products, you can get detailed air quality data for every neighborhood in Beijing (instead of being limited to 35 ground monitoring stations), and you can also find out the specific sources of pollution for every haze, so that the Beijing government can target and shut down polluting enterprises. From last year's trial run analysis compared with the actual data, Qingkong Technology's analysis and prediction error is about 10%.
Their data model comes mainly from years of collaboration between two Chinese scientists: Dr. Jun Wang, a lifelong professor at Nebraska State University, and Dr. Yang Liu, a lifelong professor at Emory University. Both are members of NASA's research program and have been working for many years on atmospheric chemistry, satellite remote sensing, and environmental protection.
QST was founded earlier this year and has five co-founders***, including two senior scientists, chairman Ye Dong, a veteran of cleantech investment in China, U.S. CEO Yu Le, who has experience in high-tech investment, and China project leader Bai Chunjue, who has eight years of experience in the environmental industry.
The project is not only socially and environmentally significant, but also commercially valuable. According to Yu Le, China's environmental big data market is expected to exceed 100 billion RMB. Users who need environmental big data analysis services include not only government agencies, but also commercial companies in many industries, such as health insurance, eco-agriculture, transportation, network maps, and so on.
In addition, air quality big data services also have a wide market prospect in the consumer sector. Consumers can be accurately informed of the air quality of their fitness, travel and tourism destinations, providing targeted travel information products for mothers, infants, chronic diseases and sensitive populations, as well as combining them with smart home IoT devices for home air purification.
Yu Le told Sina Technology that they have already cooperated with the environmental protection bureaus in Hefei and Shenyang, and have made contact with the Chinese Academy of Sciences, the Beijing Science and Technology Commission and other government agencies. Intended partners in the commercial sector include companies such as Baidu Maps, Gudong Bracelet and Hupu.com.
Yule's definition of QSTECH is the first environmental big data company with core technology in China. Qingkong Technology is currently in the process of angel round financing, and plans to raise 3-5 million dollars. It is mainly used for product development and model debugging to develop engine products for the Chinese market, which is planned to be completed within six months. Qingkong Technology will now focus on serving the Chinese market, and in the future, it also intends to provide services to India and other Asia-Pacific countries, to become a leading global provider of intelligent solutions for air quality data.
