A dataset of the observations of carbon and water fluxes in the paddy fields of Panjin (2018–2020)

Although the Liaohe River Delta wetland is the largest warm temperate coastal wetland in Asia, the long-term carbon and water fluxes in the wetland are not deeply studied, which affects the simulation accuracy of CO2 fluxes and regional carbon sinks in this region.However, the study of long-term carbon and water fluxes in the Liaohe River Delta reed wetland area is still insufficient, and long-term data monitoring and sorting are urgently needed.This dataset is the flux data of the reed wetland ecosystem in the Liaohe River Delta from 2018 to 2020, collected from the Panjin Reed Wetland Research Station of the Northeast Ecological and Agrometeorological Field Experimental Base of China Meteorological Administration.

Based on the data processing system of the China Flux Observation and Research Network (ChinaFLUX), standardized datasets of water fluxes of ecosystem carbon and key meteorological elements are established, including data files collected at half an hour, day, month and year scales. This dataset is of great significance for accurately evaluating the status and role of carbon and water fluxes in the rice field ecosystem of the Liaohe Delta in the regional and global carbon and water cycles.
