Ancillary ecological dataset at the IT-Noe Mediterranean maquis site

This archive contains additional ecological measurements collected at the IT-Noe ICOS ecosystem station, located in Porto Conte Regional Natural Park, north-western Sardinia, Italy (40.606°N, 8.151°E, 25 m a.s.l.). It includes datasets for soil respiration from 2012 to 2015 and 2022 to 2023, litterfall from 2012 to 2023, above-ground biomass from 2023 to 2025, and Leaf Area Index from 2024 to 2026. These measurements were taken across permanent plots and transects. Each dataset comes with a dedicated README file. These data complement the long-term eddy covariance flux record at IT-Noe, which is available through ICOS and FLUXNET (site code: IT-Noe).本归档文件收录了意大利撒丁岛西北部波尔图·孔特区域自然公园内IT-Noe国际碳观测系统（Integrated Carbon Observation System, ICOS）生态站的补充生态观测数据，该站地理坐标为北纬40.606°、东经8.151°，海拔25米。本数据集涵盖2012—2015年及2022—2023年的土壤呼吸观测数据、2012—2023年的凋落物量数据、2023—2025年的地上生物量数据，以及2024—2026年的叶面积指数数据。所有观测均于永久样地与样带中开展，每份数据集均配有专属自述文件（README）。本数据集补充了IT-Noe站的长期涡度协方差通量观测记录，该记录可通过ICOS与通量网络（FLUXNET）获取，站点代码为IT-Noe。
