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.

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。
