AirCore - L2 - ASA site

The AirCore is an atmospheric sampler that allows the measurement of the vertical profiles (from the surface up to about 30 km of altitude) of atmospheric mixing ratio of greenhouse gases (CO2, CH4, CO, N2O). Initially proposed by NOAA (Tans, 2009 ; Karion et al., 2010; Membrive et al. 2017), it consists in a long tube of stainless steel placed under a meteorological balloon which, in the ascending phase, empties its air by its open end and is then filled progressively by the atmospheric air during its descent phase. The captured air column is then analyzed using a Picarro CRDS analyzer and finally interpreted in terms of profiles of vertical gas mixing ratio against pressure and altitude using other instruments onboard measuring in particular pressure and/or altitude (electronic board, meteosonde, GPS beacons).

Since 2013, several versions of AirCore have been developed by LMD (CNRS / Ecole Polytechnique / ENS Paris / Sorbonne University) and have then been deployed in partnership with CNES, LSCE (CNRS / CEA / University of Versailles-Saint-Quentin-en-Yvelines), GSMA (CNRS / Université de Reims), OPGC (CNRS / Blaise Pascal University) and CARE-C (The Cyprus Institute), in various places around the globe. Regular launches are organized since 2016 at several stations that form the French AirCore program: Aire-sur-l’Adour (ASA), Traînou (TRN), Reims (MDH). Additional launches are organized during large-scale, multi-instrument field campaigns, such as MAGIC.

The development and deployment of AirCores are carried out in the framework of projects funded by the CNES, CNRS, CEA, Ecole polytechnique, IPSL, the European Union and the University of Reims Champagne-Ardenne.

The present subset of the complete AirCore-Fr network dataset comprises all Level 2 gas vertical profiles, along with Level 1 meteosonde and trajectory data, acquired by the French AirCore program for Aire-sur-l'Adour launch site only (site code : ASA) from 2018, located in Aire-sur-l’Adour balloon launch centre (43.7064°N, -0.2512°E)

空气岩心采样器（AirCore）是一款大气采样装置，可实现温室气体（CO₂、CH₄、CO、N₂O）的大气混合比从地表至约30千米高空的垂直廓线测量。该装置最初由美国国家海洋和大气管理局（NOAA）提出（Tans, 2009；Karion等, 2010；Membrive等, 2017），其结构为一根长不锈钢管，挂载于气象气球下方。气球上升阶段，采样管的开口端会排空内部空气；下降阶段，采样管则逐渐被大气空气填充。采集得到的空气柱随后通过Picarro CRDS分析仪（光腔衰荡光谱）进行分析，最终结合搭载的其他测量仪器（电子板、探空仪、GPS信标）所测得的气压与海拔数据，反演得到气体混合比随气压和海拔变化的垂直廓线。
2013年以来，法国动力气象实验室（LMD，隶属于法国国家科学研究中心CNRS、巴黎综合理工学院、巴黎高等师范学院、索邦大学）已研发出多款空气岩心采样器，并与法国国家空间研究中心CNES、路易·奈耳实验室LSCE（CNRS/法国原子能和替代能源委员会CEA/凡尔赛大学圣康坦-昂伊夫林分校）、GSMA（CNRS/兰斯大学）、OPGC（CNRS/布莱士·帕斯卡大学）以及CARE-C（塞浦路斯研究所）等机构合作，在全球多地开展部署。自2016年起，法国空气岩心采样器项目的多个站点已常态化开展发射任务，包括阿杜尔河畔艾尔（ASA）、特雷努（TRN）以及兰斯（MDH）。此外，在MAGIC等大型多仪器野外试验中也会额外组织发射任务。
空气岩心采样器的研发与部署工作，依托由法国国家空间研究中心CNES、法国国家科学研究中心CNRS、法国原子能和替代能源委员会CEA、巴黎综合理工学院、皮埃尔·西蒙·拉普拉斯研究所IPSL、欧盟以及兰斯香槟-阿登大学资助的项目开展。
本次公开的完整法国空气岩心采样器网络（AirCore-Fr）数据集子集，涵盖法国空气岩心采样器项目自2018年起，仅在阿杜尔河畔艾尔气球发射中心（站点代码：ASA，地理坐标：43.7064°N，-0.2512°E）获取的全部二级气体垂直廓线数据，以及配套的一级探空仪与轨迹数据。
