Abstract

One of the most potent greenhouse gases is methane, which is the most basic hydrocarbon in the paraffin series. With a GWP of roughly 28, this is the second most significant greenhouse gas. Since there is a lot of it in the Indian subcontinent, it is important to monitor and research this gas. This study analyses satellite readings that were taken all over the world between 2003 and 2015 and are retrieved for the Indian region. This study made use of the satellite-based SCIAMACHY and TANSO-FTS equipment. Additionally, the work examines how a change in concentration levels depends on a region's location and climate by estimating the rate of change of methane levels through time and obtaining information on the change in concentration. According to this study, it is rising quickly over the Indo-Gangetic Plain, the Northeast, and certain coastal areas. The majority of the sources are man-made, such as fossil fuels and the energy industry, as well as natural sources like wetlands. Both instruments indicate that methane content is rapidly rising in the area, depending on a number of variables and seasonal fluctuations. Methane emissions must be decreased otherwise it will be the main cause of the greenhouse effect.
