本文讨论了CLOUD-MAP（协作领先的气象和大气物理业务无人机系统开发）项目的结果，该项目致力于开发，部署和评估用于增强大气物理测量的集成小型无人机系统（sUAS）。该项目团队包括大气科学家，气象学家，工程师，计算机科学家，地理学家和化学家，以评估需求并开发在大气物理学中使用sUAS所需的先进传感和成像，强大的自主导航，增强的数据通信和数据管理能力。在协调现场测试中对系统进行年度综合评估，以验证传感器性能，同时将其集成到各种sUAS平台中。本文重点介绍了与sUAS热力学参数大气采样相关的方面，特别是传感器集成和校准/验证，特别是因为它涉及到边界层剖面。通过将测量值与已知值进行比较来验证传感器输出，包括仪表塔，无线电探空仪和其他经过验证的sUAS平台。实验，以确定传感器的位置和车辆操作的影响已经进行，传感器的吸气的一个主要因素。如果仪器包正确安装在提供足够气流和适当太阳屏蔽的位置，则测量是稳健的。
This paper discusses results of the CLOUD-MAP(Collaboration Leading Operational UAS Development for Meteorology and Atmospheric Physics) project dedicated to developing, fielding, and evaluating integrated small unmanned aircraft systems (sUAS) for enhanced atmospheric physics measurements. The project team includes atmospheric scientists, meteorologists, engineers, computer scientists, geographers, and chemists necessary to evaluate the needs and develop the advanced sensing and imaging, robust autonomous navigation, enhanced data communication, and data management capabilities required to use sUAS in atmospheric physics. Annual integrated evaluation of the systems in coordinated field tests are being used to validate sensor performance while integrated into various sUAS platforms. This paper focuses on aspects related to atmospheric sampling of thermodynamic parameters with sUAS, specifically sensor integration and calibration/validation, particularly as it relates to boundary layer profiling. Validation of sensor output is performed by comparing measurements with known values, including instrumented towers, radiosondes, and other validated sUAS platforms. Experiments to determine the impact of sensor location and vehicle operation have been performed, with sensor aspiration a major factor. Measurements are robust provided that instrument packages are properly mounted in locations that provide adequate air flow and proper solar shielding.
