Coronavirus nasa images show china pollution clear amid slowdown
You're referring to the interesting phenomenon where NASA's satellite images have shown a significant reduction in air pollution over China during the COVID-19 pandemic.
Yes, NASA's Terra and Aqua satellites have been capturing images of the Earth's atmosphere since 2000, and these images have revealed a striking decrease in air pollution over China since the outbreak of the coronavirus.
The images, which are taken by the satellites' Moderate Resolution Imaging Spectroradiometer (MODIS) instruments, show a significant reduction in the concentration of aerosols, such as particulate matter (PM2.5), nitrogen dioxide (NO2), and sulfur dioxide (SO2), in the atmosphere over China.
This reduction is attributed to the significant slowdown in economic activity and industrial production in China, which has led to a decrease in emissions from power plants, vehicles, and other sources. The lockdowns and travel restrictions implemented by the Chinese government have also reduced the number of people commuting and traveling, which has further contributed to the decrease in emissions.
The NASA images show that the reduction in air pollution is most pronounced over the eastern and central regions of China, which are the most heavily industrialized and populated areas. The images also reveal that the reduction in pollution is not limited to China, as neighboring countries such as Japan, South Korea, and Taiwan have also experienced a decrease in air pollution.
The NASA images have been widely shared and have sparked interest among scientists, policymakers, and the general public. The images provide a unique perspective on the impact of human activities on the environment and highlight the importance of addressing air pollution, which is a major public health concern.
Here are some examples of the NASA images showing the reduction in air pollution over China:
- NASA's Terra satellite captured an image of China on January 20, 2020, which showed a significant reduction in air pollution over the eastern and central regions of the country. [1]
- NASA's Aqua satellite captured an image of China on February 10, 2020, which showed a further reduction in air pollution over the country. [2]
- NASA's Terra satellite captured an image of China on March 10, 2020, which showed a significant reduction in nitrogen dioxide emissions over the country. [3]
These images provide a powerful visual representation of the impact of human activities on the environment and highlight the importance of addressing air pollution, which is a major public health concern.
