What is it about?
Visibility in many cities across the world has been improved significantly over the past few months. It is a rare upside of Covid-19 due to the decrease in the number of passenger flights. This paper explored the relationships between energy use, meteorological factors, and change in visibility in Hong Kong and was published in 2014. As stated its 3rd highlight, it was confirmed that combustion of aviation fuel adversely affected visibility. Now, please look up to the sky and enjoy the clouds or stars. That reminds us what we have been doing...

Why is it important?
Bivariate correlations show that poor visibility was significantly associated with energy use and annual mean air temperature. Multiple regression analysis indicates that the burning of aviation gasoline significantly, adversely affect visibility. Results illustrate that the number of clear days in Hong Kong will decrease, in particular due to the increase in "AIR TRAFFIC".
