MAPPING TRENDS OF CARBON DIOXIDE AND METHANE DURING MOVEMENT CONTROL ORDER IN INDUSTRIAL AREAS IN PENINSULAR MALAYSIA USING GOSAT, GOSAT-2, OCO-2, OCO-3, AND TROPOMI SATELLITES DATA

Abstract. The Malaysian government implemented the Movement Control Order (MCO) from March 18 to May 13, 2020, in an effort to curb the coronavirus disease outbreak that had spread throughout the nation. Utilizing data from GOSAT, GOSAT-2, OCO-2, OCO-3, and TROPOMI, the total column-averaged dry-air mole fraction of carbon dioxide and methane (referred as XCO₂ and XCH₄) is employed to examine the patterns of both gases throughout the MCO as well as from the same period the prior and following year. The Inverse Distance Weighting (IDW) interpolation method is utilized in mapping the XCO₂ and XCH₄ for the industrial areas in Peninsular Malaysia. The results revealed that even MCO is implemented, the XCO₂ and XCH₄ in the industrial areas are increasing year by year. By using satellites data, the XCO₂ and XCH₄ from large areas can be monitored continuously.
