Net Ecosystem Exchange chamber measurements of CO2 and latent heat fluxes at the edge effect site

Manual measurements with a tunnel-shaped flow-through chamber (covered surface area: approx. 1.6 m²) of CO2 and latent heat fluxes at the edge effect site, at several IOPs near the start of the campaign. Land use types: Wheat/fodder field (Eddy Covariance reference data available), grassland ("), poorly drained grassland spot (no reference fluxes), maize (no reference fluxes).

本研究采用隧道型流通式气室（覆盖表面积约1.6 m²），于试验启动初期的多次强化观测期（Intensive Observation Periods，IOPs）内，在边缘效应站点开展了二氧化碳与潜热通量的人工观测。本次观测涉及的土地利用类型包括：小麦/饲草田（可获取涡度协方差（Eddy Covariance）参考数据）、草地（同前）、排水不良的草地样点（无参考通量数据）以及玉米田（无参考通量数据）。
