​ACT-America: L2 In Situ CO2, CO, and CH4 Concentrations from Towers, Eastern USA

简介

该数据集提供了由大气碳和运输-美国 (ACT-America) 项目运营的仪器通信塔网络测得的大气二氧化碳 (CO2)、一氧化碳 (CO) 和甲烷 (CH4) 浓度。ACT-America 的任务为期五年，包括五次为期 6 周的密集实地活动，涵盖美国中部和东部所有 4 个季节和 3 个地区。基于塔的测量始于 2015 年初，并持续收集 CO2、CO 和 CH4 数据，以表征地面（> 100 m）碳背景条件，从而支持 ACT-America 开展的定期空中测量活动和运输建模。这些塔配备了红外腔衰荡光谱仪系统 (CRDS；Picarro Inc.)。报告了每个塔上最高采样口的数据。提供了从定期烧瓶样品到现场测量比较得出的平均间隔标准偏差和不确定度。还提供完整的塔位置、海拔、仪器高度和日期/时间信息。
