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

Abstract

Paddy fields play an important role in the study of agricultural land use and global carbon cycle. As one of the main rice producing areas in Northeast China, the Liaohe River Delta provides a good experimental platform for the study of carbon and water cycle in Paddy fields. However, due to the insufficient study of long-term carbon and water fluxes in the paddy areas of the Liaohe River Delta, there is an urgent need of long-term data monitoring and sorting. This dataset collects the observations of the flux data of the paddy field ecosystem in the Liaohe River Delta from 2018 to 2020 from the Panjin Paddy Field 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), we prepared standardized data files for the dataset of water fluxes of ecosystem carbon and key meteorological elements, including data files at hourly, daily, monthly and yearly scales. This dataset is of great significance for the accurate evaluation of the position and role of carbon and water fluxes of paddy field ecosystems in the regional and global carbohydrate circle in the Liaohe River Delta.
