Repeated measurements

Repeated field measurements of trace gas flux at the soil surface at five forest sites in Panama. Gases measured include: carbon dioxide (CO2; mg C m-2 hr-1), methane (CH4; ug C m-2 hr-1), nitrous oxide (N2O; ug N m-2 hr-1), nitric oxide (NO; ug N m-2 hr-1) and initial nitric oxide concentration (NOSt; ppb). Other data collected from the field: soil extractable nitrate (NO3; mg N kg-1) and ammonium (NH4; mg N kg-1), soil temperature (Temp; oC) and soil gravimetric water content (Moisture; g g-1). Site numbers correspond to the map shown in the supplementary material for this article.本数据集包含巴拿马境内5个森林样地的土壤表面痕量气体通量重复野外实测数据。实测气体组分包括：二氧化碳（carbon dioxide, CO₂；mg C m⁻² hr⁻¹）、甲烷（methane, CH₄；μg C m⁻² hr⁻¹）、一氧化二氮（nitrous oxide, N₂O；μg N m⁻² hr⁻¹）、一氧化氮（nitric oxide, NO；μg N m⁻² hr⁻¹）以及一氧化氮初始浓度（NOSt；ppb）。野外采集的其他数据包括：土壤浸提态硝酸盐（soil extractable nitrate, NO₃⁻；mg N kg⁻¹）、铵态氮（ammonium, NH₄⁺；mg N kg⁻¹）、土壤温度（soil temperature, Temp；℃）以及土壤重量含水率（soil gravimetric water content, Moisture；g g⁻¹）。样地编号与本文补充材料中展示的地图一一对应。
