Assessing Indonesia air pollution using Sentinel-5P remote sensing air-RGB model

One of the environmental problems that are a threat to humans today is air pollution. Air pollution can cause one in nine deaths and kill about three million people each year. Air pollution can originate naturally, such as volcanic eruptions, and unnaturally like anthropogenic. Some of the air pollution gases include SO₂, NO₂, and CO. Air pollution data can be obtained from remote sensing data especially from Sentinel-5P satellite. Air-RGB modelling on the three pollutant gases can produce an indication of the dominant pollutant gas in an area. The way to do Air-RGB modelling is to form three scenarios, namely red for CO, green for NO₂, and blue for SO₂. Air-RGB data is combined with air pollution charts based on latitude longitude to see trends in air pollution based on latitude and longitude in an area. In 34 provincial capitals in Indonesia, there was a ternary scatter to see the trend of air pollution gases. The results of the study were combined with secondary data to support the causes of decreasing and increasing air pollution. Those pollutions included forest fires, hotspots, volcanic eruptions, population density, and other data related to human activities. This research is expected to be a consideration for the government in handling air pollution in Indonesia.
