Trace Gas Fluxes on the Main Cropping System Experiment at the Kellogg Biological Station, Hickory Corners, MI (1991 to 2012)

Dataset Abstract Trace gases (nitrous oxide, methane, and carbon dioxide) have been measured on the LTER Main Site since 1991 and on Successional and Forest sites since 1993. Trace gas fluxes are measured twice monthly or monthly until the ground freezes using permanently-installed, in-situ static chambers. CH4 and N2O are analyzed with gas-chromatography and CO2 with an infrared gas analyzer. Soil moisture and temperature are measured during sampling. original data source http://lter.kbs.msu.edu/datasets/16

数据集摘要：自1991年起，研究团队便在长期生态研究（Long Term Ecological Research, LTER）主站点开展痕量气体（一氧化二氮、甲烷与二氧化碳）监测工作，并自1993年起在演替站点与森林站点同步开展此类监测。研究人员采用永久安装的原位静态箱法，在地面封冻前以每月两次或每月一次的频率测定痕量气体通量。采用气相色谱法对甲烷（CH4）与一氧化二氮（N2O）进行分析，利用红外气体分析仪检测二氧化碳（CO2）；采样过程中同步测定土壤含水率与土壤温度。原始数据来源：http://lter.kbs.msu.edu/datasets/16
