一个新的对流层低层大气测量系统已经研制成功并进行了测试。介绍的小型无人气象观测器（SUMO）是基于一个重量轻的商用模型飞机，配备了自动驾驶仪和气象传感器的温度，湿度和压力。在冰岛中部为期5周的FLOHOF（HofsjoUkull上方和周围的水流）实地活动中，该系统已于2007年7月/8月成功测试。大气剖面的温度，湿度，风速和风向已被确定到3500米以上的地面。此外，SUMO适用于距离发射场4公里以内的水平勘测也已获得批准。在2008年2月/3月在斯匹次卑尔根岛及其周围进行的为期3周的活动中，SUMO系统也证明了其在恶劣的极地条件下的功能，在地面温度为-20 °C和风速高达15 m s-1的情况下达到1500 m以上的高度。SUMO翼展80厘米，身长75厘米，重量在600克以下，即使在偏远地区也易于运输和操作。一个SUMO单元的直接材料成本，包括飞机，自动驾驶仪和传感器，低于1200欧元。假设每个机身至少有十分之几的飞行次数，SUMO提供了一个具有成本效益的测量系统，具有很大的潜力，可以弥补气象桅杆/塔和无线电探空仪之间合理的大气测量系统的现有观测差距。
A new system for atmospheric measurements in the lower troposphere has been developed and successfully tested. The presented Small Unmanned Meteorological Observer (SUMO) is based on a light-weighted commercially available model airplane, equipped with an autopilot and meteorological sensors for temperature, humidity and pressure. During the 5 week field campaign FLOHOF (Flow over and around HofsjoUkull) in Central Iceland the system has been successfully tested in July/August 2007. Atmospheric profiles of temperature, humidity, wind speed and wind direction have been determined up to 3500 m above ground. In addition the applicability of SUMO for horizontal surveys up to 4 km away from the launch site has been approved. During a 3 week campaign on and around Spitsbergen in February/March 2008 the SUMO system also proved its functionality under harsh polar conditions, reaching altitudes above 1500 m at ground temperatures of -20 °C and wind speeds up to 15 m s-1. With its wingspan of 80 cm, its length of 75 cm and its weight of below 600 g, SUMO is easy to transport and operate even in remote areas. The direct material costs for one SUMO unit, including airplane, autopilot and sensors are below 1200 Euro. Assuming at least several tenths of flights for each airframe, SUMO provides a cost-efficient measurement system with a large potential to close the existing observational gap of reasonable atmospheric measurement systems in between meteorological masts/towers and radiosondes.
