Abstract

Carbon dioxide (CO₂) is an inodorous and transparent gas, and naturally originates in our atmosphere. Due to its optical characteristics, CO₂ is the most important greenhouse gas and play a key role in climate change due to an effective thermal infrared (IR) radiation absorber. Satellite observations of atmospheric carbon dioxide (CO₂) can significantly improve our knowledge about the sources and sinks of CO₂. The remote sensing satellite, namely Greenhouse Gases Observing Satellite (GOSAT) was employed to investigate the spatial and variations of CO₂ column-averaged dry airmole fractions, denoted XCO₂ over Peninsular Malaysia from January 2013 to December 2013. The analysis of CO₂ in the study area shows the significant differences between northeast monsoon (NEM) and the southwest monsoon (SWM). During NEM season, cold air outbreaks from Siberia spreads to equatorial region in the form of north-easterly cold surge winds and associated with a low-level anticyclone over Southeast Asia. Inversely, air masses from the southwest contribute to long–range air pollution due to transportation of atmospheric CO₂ by wind is associated with biomass burning in Sumatra, Indonesia. The GOSAT data and the Satellite measurements are able to measure the increase of the atmosphere CO₂ values over different regions.
