Analysis of the Relative Change in Methane Gas Emissions in Babil Governorate

Abstract

The research aims to clarify the relative change in methane gas emissions at the air quality monitoring station in Babil Governorate, as it is one of the primary factors affecting the activities of living organisms. The researchers relied on data and information from the NASA website for surface weather predictions for the period (2010-2021), using statistical methods and selecting the most important methods to calculate methane gas in the study area. Consequently, the relative change in the study area was analyzed and applied to the Babil station. This research will depend on using the general trend method and relative change to clarify the changes in methane gas in the study area, to detect the general trend and rate of change in the study area, and to express the trend coefficient as a percentage. The study concluded that:

1. There is temporal variation in methane gas values during the study period, with the highest general trend recorded in March (0.0066 ppm) and the lowest general trend in April (-0.03 ppm).
2. There was a variation in general trend values, with the highest relative change rate recorded in July and August (0.526%) and the lowest rate in April (1.587%).
3. All months recorded a positive trend except for April, which recorded a negative trend.
