一款紧凑、轻便的大气气体分析仪已被集成到美国国家航空航天局（NASA）传感器集成环境远程研究飞机（SIERRA）无人机（UAV）上，并部署用于对甲烷、二氧化碳和水蒸气进行高精度、1赫兹的测量。该分析仪用于测量飞行中的气体浓度，并演示该系统在低至10米的高度和偏远地区提供测量。第一次飞行是在加利福尼亚州的Crows Landing进行的，这是一个农业基地，水的浓度显示出明显的结构和明显的特征，远远超出了测量噪声。在美国宇航局北极海冰表征实验（CASIE）之前，该仪器随后被部署在挪威的斯瓦尔巴群岛。在斯瓦尔巴群岛飞行期间，CO2和CH4的浓度变化很小，但水的浓度变化很大，随着飞机在跑道形状的飞行模式中反复移动而振荡。水浓度高的地区与低洼地区相对应，低洼地区收集了附近Vestre Broggerbreen冰川的径流。这种新颖的集成仪器-飞机系统允许在低海拔和偏远或危险地区进行更多和有效的二氧化碳、甲烷和水蒸气浓度测量。(C) 2012 Elsevier B.V.版权所有
A compact, lightweight atmospheric gas analyzer has been integrated into and flown on the National Aeronautics and Space Administration (NASA) Sensor Integrated Environmental Remote Research Aircraft (SIERRA) unmanned aerial vehicle (UAV) and deployed to make highly accurate, 1 Hz measurements of methane, carbon dioxide, and water vapor. The analyzer was used to measure gas concentrations in flight and to demonstrate the system for providing measurements at altitudes as low as 10 m and in remote locations. The first flights were conducted at Crows Landing, CA, an agricultural site, with H2O concentrations showing distinct structure and sharp features that were well outside of the measurement noise. The instrument was then deployed in Svalbard, Norway prior to the NASA Characterization of Arctic Sea Ice Experiment (CASIE). During the Svalbard flight, there was minimal variation in the CO2 and CH4 concentrations, but the water concentration changed dramatically, oscillating as the aircraft moved repeatedly through its racetrack shaped flight pattern. The regions of high water concentration corresponded to low-lying areas which collect runoff from the nearby Vestre Broggerbreen glacier. This novel, integrated instrument-aircraft system allows more numerous and efficient measurements of carbon dioxide, methane, and water vapor concentrations at low-altitudes and in remote or dangerous locations.
