An Integrated Assessment

Your challenge is to integrate various Earth Observation-derived features with available socio-economic data in order to discover or enhance our understanding of COVID-19 impacts.

Brightness, emissions and the quarantine assessing

Summary

Our project is aimed to improve the SIR model in predicting the COVID-19 based on the brightness of cities and find the correlation between the quarantine abidance and changes in atmospheric composition. We discovered the dependence between regions’ brightness, their populations and hence the number of social interactions. Thus, basing on our models, we got the result that showed proportional dependence of change in CO composition in the atmosphere and the number of social contact between people

How We Addressed This Challenge

We intended to answer the question "Is there any prooved way to assess quarantine quickly and efficiency in different areas according to the satellite data of cities brightness and gas contents?”. We have also concluded how can the change in brightness correspond to the change in human activity. We discovered that quarantine restrictions make a major difference in CO concentration only while having almost no impact on O3 and UFPs.

Overall, we have included multiple factors building the chain to predict the COVID-19 spreading.

How We Developed This Project

What inspired your team to choose this challenge? What was your approach to developing this project? How did you use space agency data in your project? What tools, coding languages, hardware, the software did you use to develop your project? What problems and achievements did your team have?

During the project advancements, we have used Intelij Idea primarily to develop a Java app for building multigraphs and analyzing data. We created SIR mathematical model, that predicts the spread and epidemiological situation. Firstly, we derived the empirical dependence of the brightness of the city on its population. For this, we used ImageJ software. Total brightness was estimated as Area(in pixels)*mean brightness, thus we found almost linear dependence of the brightness of the region on its population (we implemented MS Excel and Google sheet functions to assess linear trends). Also, it’s known that there is a dependence between the size of the city and the average number of social contacts between people (“The scaling of human interactions with city size” - https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4233681/). The number of social contacts, in turn, influences the speed of the virus spread.

By analyzing data of different emissions we detected that significant changes could be observed in CO concentration only. Thus, we compared CO concentration changes and the number of social contacts between people. Hence, we detected that the average number of social contacts between people is proportionally dependent on the changes in CO concentration - the data gathered by NASA satellites.

Overall, we got the coefficient of transmission between people, which we inserted in our model. As you can see on the last slide, our model does a good job of predicting the future prognosis of the pandemical situation and can be used for further investigation.
