塔克拉玛干沙漠位于我国新疆南部的塔里木盆地中央，地处77°~90°E，37°~41°N，面积33.76×104 km2，是中国最大和世界第二大流动沙漠。塔克拉玛干沙漠作为干旱地区典型的风沙地貌，风沙灾害频繁，年平均出现沙尘暴30 d以上，扬沙天气多达70 d，浮尘天气高达200 d，是我国沙尘天气的多发中心之一，也是全球沙尘气溶胶的重要来源。作为全球典型的沙漠生态系统系统之一，关于塔克拉玛干沙漠生态系统温室气体收支规律的研究尚在起步阶段。本数据集来自中国气象局乌鲁木齐沙漠气象研究所在塔克拉玛干沙漠腹地建立的新疆塔克拉玛干沙漠气象国家野外科学观测研究站西站在2023年3月的开展的温室气体观测试验。数据集不仅为沙漠生态系统碳平衡模型的建立与验证提供数据支持，也为沙漠生态系统应对气候变化的管理提供科学依据。FCO2 LIN表示二氧化碳通量，FCH4 LIN表示甲烷通量，FN2O LIN表示氧化亚氮通量。
