NASA Stats Show Drastic Reduction In Global Air Pollution During Covid-19

We all agree what a crazy ride 2020 has been. And it seems that there is still an eternity left before this all comes to an end. Our whole population went through some challenging phases, yet certain collected data shows the effects otherwise.

The data collected shows that staying at home ended in less pollution this year. NASA has come up with these results based on the information gathered by its GEOS atmospheric model and has come up with figures with or without COVID-19 that prove that the world requires lesser human activity.

The contrasting results were shown at the 2020 International Conference for High-Performance Computing, Networking, Storage, and Analysis.

From February, global nitrogen dioxide concentrations have lessened approximately 20% compared to the computer model of the world without COVID-19.

“In certain ways, I was amazed by how much it minimized,” demonstrated lead author Christoph Keller from Universities Space Research Association (USRA) at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “Various countries have already done an awe-inspiring job in dropping their nitrogen dioxide concentrations over the past decades as a result of clean air regulations, but what our results specifically show is that there exists an alarming human behavior-driven contribution.”

In total scrutiny of 46 countries, 50 of the 61 observed cities demonstrate a reduction range between 20-50%.

“You can, at certain times, even identify the decrease in nitrogen dioxide before the official policies going into place,” added co-author Emma Knowland with USRA at Goddard’s GMAO. “People may be reduced their transit because the talk of the COVID-19 threat was already occurring before we were ultimately asked to shut down.”

The model was built on a “normal” 2020, not very dissimilar compared to other years. People were permitted to act the same as before, stepping outside, making use of transportation in large numbers, and no lockdowns took into consideration. The results have appeared that the same number of pollutants would be added to the air.

Afterward, that model and this year’s actual observations created by satellites during shutdowns produced the results. In Wuhan, China, the lockdowns spread through the countries and cities and resulted in keeping the air less polluted. About 60 percent of emissions happened to have split from what models expected.

NASA released various cities’ data; for example, a 60% drop was shown in Milan and Madrid, while New York lined up with a 45% reduction.
Well, the Earth finally happens to have taken a deep sigh of relief.
