中文摘要: 利用垂直起降固定翼无人机搭载温湿传感器,针对2018—2019年冬季、春季典型天气过程,在上海开展了20次无人机试验,获得有效数据19组,并基于同站自动站和探空资料,评估探测资料精度,分析了无人机探测在城市地区的适用性。结果表明:无人机试验能获得较高精度的城市近地层探测资料,冬季和春季试验获得的地面气温(相对湿度)与自动站的平均偏差分别为-0.5 ℃(4.9%)和0.9 ℃(-5.9%);无人机探测的贴地逆温等结构及其变化特征与探空资料一致,说明无人机对城市地区近地层结构及其演变特征有较好的探测能力。
Abstract:This study is to demonstrate whether the accurate and high spatio-temporal resolution thermodynamic profiles of the lower atmospheric boundary layer (ABL) over the urbanized areas could be obtained by small unmanned aircraft system (sUAS). Twenty flights in total were conducted in Shanghai during winter (in December 2018) and spring (in March 2019) months, and 19 profiles (surface-200 m) of temperature and relative humidity were collected. Measurements from automatic weather station (AWS) and radiosonde at the same site were used to evaluate these profiles. The results showed that surface temperature and relative humidity observed by sUAS are close to those from AWS, with the mean differences of -0.5℃, 4.9% for winter flights and 0.9℃, -5.9% for spring flights. The general features of temperature and relative humidity profiles obtained by sUAS are consistent with those from radiosonde, such as temperature inversion near the ground and so on. These findings indicate that sUAS is capable of revealing detailed structures and variations of the lower ABL over the urbanized areas.
