Nimmo High Plains OzFlux Tower Site

Flux data from the Nimmo High Plains site in the Monaro region of NSW (36 12'57.4"S, 148 33;10.0"E; 1337m). Site is a seasonally grazed (bovine), sub-alpine grassland system comprised principally of Poa spp. and various herbaceous species. Site is subject to seasonal (May-October), intermittent snow cover. Carbon dioxide, water vapour and heat are quantified using an open-path eddy covariance technique. Additional measurements at this site include: temperature, relative humidity, incoming/outgoing shortwave radiation, incoming/outgoing longwave radiation, global and diffuse PAR, outgoing PAR, soil heat flux, soil temperature (5,10,20,30,40,50 cm depths) and soil moisture (5,10,20,30,40,50 cm depths) and rainfall.本数据集收录了新南威尔士州（New South Wales）莫纳罗地区尼姆高平原站点的通量观测数据，该站点地理坐标为南纬36°12'57.4"、东经148°33'10.0"，海拔高度1337米。该站点为受季节性牛科牲畜放牧的亚高山草原生态系统，主要优势物种为早熟禾属（Poa spp.）植物与多种草本类群，且会经历每年5月至10月的间歇性积雪覆盖。本研究采用开路式涡度协方差技术对二氧化碳、水汽与热量进行定量观测。该站点的附加观测项目还包括：气温、相对湿度、入射与出射短波辐射、入射与出射长波辐射、总光合有效辐射（Photosynthetically Active Radiation, PAR）与散射光合有效辐射、出射光合有效辐射、土壤热通量、5、10、20、30、40、50厘米深度的土壤温度与土壤含水量，以及降雨量。
