| Abstract | Rapid increase in concentration of Greenhouse Gases (GHGs) aggravates global warming of the Earth's atmosphere. Methane as a major component of GHGs, is necessarily to be monitored its emission rate as well as emission quantity. The objective of this study is to develop mathematical models for estimation of methane emission from deep-water rice field, using information extracted from satellite images. Methodology proposal in the study consists of two models: firstly ground truth data of monthly biomass of rice and average methane emission rate were analyzed to develop methane emission rate model. Secondly biomass of rice and various reflectance of wavelength: obtained from satellite images were investigated. It has been found that Landsat TM band 3, band 4, band 5, band 7 and NDVI as well as NOAA-AVHRR band 1, band 2 and NDVI are well related to biomass of rice, which can be used to estimate biomass of rice, so called Remote Sensing biomass model. Finally estimation of methane emission can be manipulated by using methane emission rate model coupling with RS biomass model based on data from satellite imageries. Comparison between estimated methane emission from satellite images and experimental methane emission data measured at Prachinburi Rice Research Center reveals that the methodology proposed can be used to estimate methane emission from deep-water rice field with satisfied accuracy particularly during reproductive stage of rice and maturation. |
