本文介绍了一个新的数据集，从冰在中间层（AIM）的云成像和粒子大小（CIPS）仪器，在50-55公里的高度重力波（GW）可以推断。CIPS对水平波长为15至600 km、垂直波长超过15 km的全球微波敏感。在CIPS观测GW的几个例子，包括波与安第斯山脉，岛屿地形，对流，极地夜间急流，对流层急流。CIPS数据中的GW特征与2016年6月大气红外探测器（AIRS）的近同步但较低高度的测量结果非常一致。结果表明，CIPS测量与其他仪器相结合的力量，以调查GW过滤和传播。CIPS数据集开辟了新的研究领域，使人们能够在近全球范围内对中层大气中的全球变暖进行全面调查。
This paper describes a new data set from the Aeronomy of Ice in the Mesosphere (AIM) Cloud Imaging and Particle Size (CIPS) instrument, from which gravity waves (GWs) at an altitude of 50–55 km can be inferred. CIPS is sensitive to GWs with horizontal wavelengths from ~15 to 600 km and vertical wavelengths longer than 15 km. Several examples of GWs in CIPS observations are shown, including waves associated with the Andes Mountains, island topography, convection, the polar night jet, and the tropospheric jet stream. GW signatures in the CIPS data are shown to agree well with near‐coincident but lower altitude measurements from the Atmospheric Infrared Sounder (AIRS) in June of 2016. Results suggest the power of combining CIPS measurements with those from other instruments to investigate GW filtering and propagation. The CIPS data set opens new areas of inquiry, enabling comprehensive investigations of GWs in the middle atmosphere on a near‐global scale.
