ACT-America: Profile-based Planetary Boundary Layer Heights, Eastern USA

This dataset provides profile-based estimates of the height to the top of the planetary boundary layer (PBL), also known as the atmospheric boundary layer (ABL), in meters above mean sea level estimated from meteorological measurements acquired during ascending or descending vertical profile flight segments during NASA's Atmospheric Carbon and Transport - America (ACT-America) airborne campaign. ACT-America flights sampled the atmosphere over the central and eastern United States seasonally from 2016 - 2019. Two aircraft platforms, the NASA Langley Beechcraft B-200 King Air and the NASA Goddard Space Flight Center's C-130 Hercules, were used to collect high-quality in situ measurements across a variety of continental surfaces and atmospheric conditions.

本数据集提供基于廓线的行星边界层（Planetary Boundary Layer, PBL，又称大气边界层（Atmospheric Boundary Layer, ABL））顶部高度的估算值，该高度以平均海平面以上米数为单位，估算所用数据来自美国国家航空航天局（National Aeronautics and Space Administration, NASA）大气碳与运输-美洲（Atmospheric Carbon and Transport - America, ACT-America）机载飞行任务期间，垂直廓线上升或下降飞行航段获取的气象测量结果。ACT-America任务于2016至2019年间按季节对美国中部和东部地区的大气开展采样观测。本次任务搭载两类机载平台：美国国家航空航天局兰利研究中心的比奇B-200“空中国王”（Beechcraft B-200 King Air）飞机，以及美国国家航空航天局戈达德太空飞行中心的C-130“大力神”（C-130 Hercules）运输机，用于在多样的大陆下垫面与大气条件下采集高质量的原位测量数据。
