CEDAR: An Investigation of the Properties and Sources of Small-Scale Gravity Waves at Low Latitudes as Part of the ALOHA-93/CADRE Campaigns

ALOHA-93和CADRE活动的中心是低纬度和赤道纬度的中层大气动力学测量。作为ALOHA-93/CADRE活动的一部分，将对夏威夷群岛半径约500公里范围内的小尺度重力波的性质和来源进行详细调查。特别是，OI (557.7 nm), Na （589.2 nm）和近红外OH发射的连续观测将为研究水平和垂直重力波传播，水平各向异性，风过滤和波耗散提供全面的数据集。这些数据将大大扩展与机载测量进行相关研究的范围，并将与其他地面测量高度互补。每个发射高度的图像数据所提供的二维波信息对于研究太平洋中部小尺度重力波的主要来源将特别有用。

The ALOHA-93 and CADRE campaigns are centered one measurements of middle atmosphere dynamics at low and equatorial latitudes. As part of the ALOHA-93/CADRE campaign, a detailed investigation will be made of the properties and sources of small scale gravity waves that occur within about 500 km radius of the Hawaiian Islands. In particular, sequential observations of the OI (557.7 nm), Na (589.2 nm) and near infrared OH emissions will be used to provide a comprehensive data set valuable for the investigation of both horizontal and vertical gravity wave propagation, horizontal anisotropy, wind filtering and wave dissipation. These data will significantly extend the range over which correlative studies can be made with the airborne measurements and will be highly complementary to the other ground based measurements. The 2- dimensional wave information provided by the image data at each emission altitude will be particularly useful in the investigation of the dominant sources of small scale gravity waves over the mid- Pacific ocean.
