Abstract:

This work proposes a satellite based Cyber-Physical System for impact analysis of wildfire. Wildfire can may occur due to human activities or natural phenomenon such as lightning and have substantial impact on living beings and the environment. Analysis of Australia wildfire shows a drastic change in vegetation and atmosphere of Australia. Biomass burning is one of major source of emission of pollutants. The major air pollutants are carbon dioxide ( ), carbon monoxide ( ), nitrogen dioxide ( ), ozone ( ), sulfur dioxide ( ), formaldehyde ( ) and particulate matter (PM). To monitor air quality, we have to investigate the extent of these gases in air. Traditional method involving installation of embedded systems-based air quality measurement equipment are too much costly and have limitations as it can be installed in a limited area. Satellite-based Cyber-Physical System is an alternate technique for detecting damages caused by wildfire. This paper aims to investigate impact of wildfire on atmosphere and vegetation of Australia, through Satellite-based Cyber-Physical System, while employing Sentinel-5 Precursor (Sentinel-5p) and Landsat 8 satellites using Google Earth Engine. Using our proposed Cyber-Physical System, we processed pre-fire dataset (2019-11-05 -to- 2019-11-07) and post-fire dataset (2019-11-08 -to- 2019-11-13) of Sentinel-5p and Landsat 8 in utilizing Google Earth Engine. Our analysis shows a severe decrease, of nearly 100%, in healthy vegetation and drastic increase of almost 112% in , 260% in , 264% in aerosol index, 144% in in New South Wales and its nearby cities of Australia. Our analysis proved that as compared to up-to-date fire monitoring systems, our proposed Satellite-based Cyber-Physical System have a great potential in making critical decisions and shows appreciable performance in productivity, safety, reliability and serviceability.
