Spatial-Temporal Changes of Methane Content in the Atmosphere for Selected Countries and Regions with High Methane Emission from Rice Cultivation

Irrigated and flooded rice is associated with methane (CH4) emissions. CH4 is one of the most important anthropogenic greenhouse gases (GHG) in the atmosphere. Nowadays, mapping CH4 content at a global scale is possible using satel...
