摘要。本研究展示了新开发的系绳飞艇（TAB）系统的首次环境监测现场活动，以调查复杂地形上的小气候。在矿山和尾矿池等复杂地形中使用系留气球是一种新颖的方法，也是本研究的重点。TAB系统于2018年5月在加拿大北部的一个采矿设施全面开发并启动。本研究描述了关键的设计特点、机载传感器的有效载荷、校准和TAB系统的观测结果。该系统测量了大气边界层前几十米的气象条件，包括风速矢量、温度、相对湿度和压力的分量。测量是在该设施的两个主要地点进行的：(i)尾矿库附近和（ii）矿坑内。TAB在不同的白天时间（例如白天与夜晚）和地点（尾矿库附近与矿山内部）测量了大气的动态。这些动力学包括与流动动量和能量有关的平均和湍流统计，它们在未来研究中对设施发射通量的理解至关重要。此外，TAB还可以提供边界条件和验证数据集，以支持各种运输模式的中尺度弥散建模或计算流体动力学模拟。
Abstract. This study presents the first environmental monitoring field campaign of a newly developed Tethered Air Blimp (TAB) system to investigate the microclimate over a complex terrain. The use of a tethered balloon in complex terrains such as mines and tailings ponds is novel and the focus of the present study. The TAB system was fully developed and launched at a mining facility in northern Canada in May 2018. This study describes the key design features, the sensor payload on board, calibration, and the observations made by the TAB system. The system measured meteorological conditions including components of wind velocity vector, temperature, relative humidity, and pressure over the first few tens of metres of the atmospheric boundary layer. The measurements were made at two primary locations in the facility: (i) near a tailings pond and (ii) in a mine pit. TAB measured the dynamics of the atmosphere at different diurnal times (e.g. day versus night) and locations (near a tailings pond versus inside the mine). Such dynamics include mean and turbulence statistics pertaining to flow momentum and energy, and they are crucial in the understanding of emission fluxes from the facility in future studies. In addition, TAB can provide boundary conditions and validation datasets to support mesoscale dispersion modelling or computational fluid dynamics simulations for various transport models.
