Red Dirt Melon Farm Flux Data Release 2023_v1

This release consists of flux tower measurements of the exchange of energy and mass between the surface and the atmospheric boundary-layer using eddy covariance techniques. Data were processed using PyFluxPro (v3.5.0) as described by Isaac et al. (2017). PyFluxPro produces a final, gap-filled product with Net Ecosystem Exchange (NEE) partitioned into Gross Primary Productivity (GPP) and Ecosystem Respiration (ER).
The flux station was established in August 2011 while the site supported tropical savanna. The site was part of a deforestation experiment measuring greenhouse gas exchange during conversion of forest to farmland. The land was being cultivated for watermelon production from 2013.

本数据集包含采用涡度协方差技术（eddy covariance techniques）测得的地表与大气边界层间能量和物质交换的通量塔（flux tower）观测数据。数据采用PyFluxPro（v3.5.0）进行处理，处理流程参照Isaac等人2017年的研究描述。PyFluxPro可生成经过间隙填充（gap-filled）的最终数据集，将净生态系统交换（Net Ecosystem Exchange, NEE）划分为总初级生产力（Gross Primary Productivity, GPP）与生态系统呼吸（Ecosystem Respiration, ER）。
该通量站于2011年8月建成，彼时该站点区域为热带稀树草原（tropical savanna）。该站点曾参与一项毁林实验，用于监测森林转为农田过程中的温室气体交换。自2013年起，该地块被开垦用于西瓜种植。
