According to BBC bushfire also broke out in suburbs of Sydney, which is counted in the largest cities of Australia. Fire actually started from November 8th, 2019. Red rectangle over Figure 1 highlights the affected cities of Australia.

As Burning of bushes counts in anthropogenic process and has been a detriment to environment. It involves the production of;
So keeping in mind these disadvantages of forest and bushfires, Remote Sensing team of National Center of Big Data and Cloud computing(NCBC) inspected Australian atmosphere using Google Earth Engine(GEE). We processed dataset(November 14, 2019) of Sentinel-2 satellite in GEE. Figure 2 shows view of Australian atmosphere through Sentinel-2 satellite and the smoke on affected cities. Furthermore, the smoke direction is from West to East due to wind direction.

After successfull detection of bushfire in NSW that hit Sydney, we were interested in finding effects on gases of Australian atmosphere. So, we processed more datasets(No2, CO, HCHO, Aerosel Index) of Sentinel-5P satellilte in order to detect changes in composition of Australian atmosphere. Figure 3 to Figure 6 shows the dramatical change in composition of these gases over Australian atmosphere due to bushfires in NSW.
