研究环境和COVID-19

Today is World Health Day and NASA’s Earth Science Division is using information from our Earth-observing satellites, surface sensors, and computer-based datasets to study the environmental, economic, and societal impacts of the COVID-19 pandemic and to determine whether environmental factors influence the spread of the virus.

While scientists around the world often have been confined to their homes during the COVID-19 pandemic, Earth observing satellites continue to orbit and send back images that reveal connections between the pandemic and the environment. NASA began funding eight new projects last fall to look at COVID-19 and the environment.

This image shows the ECOSTRESS land surface temperature variations measured on May 22, 2020, during the full lockdown period over an area centered on the Great Mall in Milpitas, California. Christopher Potter, a research scientist at Ames Research Center, is using such images to see how California’s shelter-in-place mandate in the San Francisco Bay Area has reduced the number of cars on the road and changed how parking lots, highways, and large industrial buildings’ surfaces absorb sunlight and reflect infrared heat.

今天是世界卫生日，美国宇航局地球科学部正在利用地球观测卫星、地表传感器和基于计算机的数据集提供的信息，研究COVID-19大流行对环境、经济和社会的影响，并确定环境因素是否会影响病毒的传播。

虽然在COVID-19大流行期间，世界各地的科学家通常都被限制在家中，但地球观测卫星继续在轨道上运行并发回图像，揭示了大流行与环境之间的联系。美国宇航局去年秋天开始资助8个新项目，研究COVID-19和环境。

该图显示了在整个锁定期间，以加利福尼亚州米尔皮塔斯大商场为中心的区域在2020年5月22日测得的ECOSTRESS陆地表面温度变化。艾姆斯研究中心的研究科学家克里斯托弗-波特（Christopher Potter）正在使用这样的图像来了解加州在旧金山湾区的就地避难所是如何减少道路上的汽车数量，并改变停车场、高速公路和大型工业建筑的表面如何吸收阳光和反射红外线热量。
