摘要。作为EUREC4A（阐明云环流耦合在气候中的作用）野外活动的一部分，该活动于2020年1月和2月在巴巴多斯附近的热带大西洋西部进行，法国SAFIRE ATR42研究飞机在对流层下层进行了19次飞行。每次飞行都遵循一种共同的飞行模式，对云基层周围、云下层不同高度、靠近海面和较低的自由对流层的大气进行采样。飞机的有效载荷包括一个水平方向的后向散射激光雷达和一个多普勒云雷达，一个向上看的多普勒云雷达，微物理探针，一个用于水同位素的空腔衰落光谱仪，一个多波长辐射计，一个可见光相机和多个气象传感器，包括用于湍流测量的快速速率传感器。利用该仪器，ATR对信风云的宏观物理和微观物理特性及其热力学、湍流和辐射环境进行了表征。本文介绍了机载操作、飞行分割、仪器仪表、数据处理和由ATR测量产生的EUREC4A数据集。它表明，用不同技术和采样测量的ATR对湿度、风和云基云分数的测量结果在内部是一致的，气象测量结果与从飞越的飞机（HALO）发射的下投探空仪的估计结果是一致的，水同位素测量结果与巴巴多斯云天文台的数据有很好的相关性。这种一致性表明，在EUREC4A期间，ATR测量的湿度、风、云基云分数和水同位素组成是可靠的。它还证实，通过重复的飞行模式，ATR和HALO测量提供了统计上一致的信风云及其环境样本。ATR数据集可在表11指定的地点免费获得。
Abstract. As part of the EUREC4A (Elucidating the role of cloud-circulation coupling in climate) field campaign, which took place in January and February 2020 over the western tropical Atlantic near Barbados, the French SAFIRE ATR42 research aircraft conducted 19 flights in the lower troposphere. Each flight followed a common flight pattern that sampled the atmosphere around the cloud-base level, at different heights of the subcloud layer, near the sea surface and in the lower free troposphere. The aircraft's payload included a backscatter lidar and a Doppler cloud radar that were both horizontally oriented, a Doppler cloud radar looking upward, microphysical probes, a cavity ring-down spectrometer for water isotopes, a multiwavelength radiometer, a visible camera and multiple meteorological sensors, including fast rate sensors for turbulence measurements. With this instrumentation, the ATR characterized the macrophysical and microphysical properties of trade-wind clouds together with their thermodynamical, turbulent and radiative environment. This paper presents the airborne operations, the flight segmentation, the instrumentation, the data processing and the EUREC4A datasets produced from the ATR measurements. It shows that the ATR measurements of humidity, wind and cloud-base cloud fraction measured with different techniques and samplings are internally consistent, that meteorological measurements are consistent with estimates from dropsondes launched from an overflying aircraft (HALO), and that water isotopic measurements are well correlated with data from the Barbados Cloud Observatory. This consistency demonstrates the robustness of the ATR measurements of humidity, wind, cloud-base cloud fraction and water isotopic composition during EUREC4A. It also confirms that through their repeated flight patterns, the ATR and HALO measurements provided a statistically consistent sampling of trade-wind clouds and of their environment. The ATR datasets are freely available at the locations specified in Table 11.
