AN041 - 可现场部署的 Picarro G2508 和 Eosense eosAC/eosMX 在长期或周期性淹水土壤的应用
漫灌的农田土壤是二氧化碳(CO2)、甲烷(CH4)和氧化亚氮 (N2O)等温室气体(GHG)的重要来源(Linquist 等人,2011;Oertel 等人,2016)。由于这些生态系统具有高度的时空异质性,因此需要连续测定痕量气体浓度,以便更好地监测其排放模式和量化净生态系统通量。在漫灌期间,测量地表通量是一项具有挑战性的工作,但是错过这些时期,可能会显著地低估每年的 CH4 排放量,并有可能高估 N2O 的排放量。本文我们通过对 Eosense eosAC 自动化呼吸室系统进行改造,并将 Picarro G2508 温室气体分析仪置于改造过的 Bonar 塑料保温箱中,对定期漫灌田地进行了连续测定。
