CH4 emissions in paddy field and relative code

 Jurong Ecological Experimental Station, established by Nanjing University in April 2015, has a eddy flux tower measuring the CO2, H2O and CH4 fluxes. This station is located at the middle-lower Yangtze River Plain, China (31°48’24.59” N, 119°13’2.15” E).The field follows a typical rice-follow rotation with straw incorporation. Generally, the rice season begins in June and ends in late October, with water management practices consistent with local agricultural norms.To assess responses of CO₂ and CH₄ fluxes to the summer 2022 heatwave-drough, we calculate seasonal (June–August) sums of GPP, Re, NEP, and CH₄ fluxes for each year during 2021-2024 along the climatic variables.
