%X During the midstream test in 2012, two GPS radiosondes, Vaisala and Changfeng, were used to carry out radiosonde observation before and after aviation flights such as CASI / Sasi, TASI and widas, so as to obtain characteristic atmospheric profile data such as wind temperature and wet pressureThe data is used to support the atmospheric correction of aerial remote sensing images and satellite images, as well as meteorological analysis Observation sites: Wuxing village and Gaoya hydrological station in the middle reaches of Heihe River, and a rou super station in the upper reaches The coordinates of the release point of Wuxing village are: 38 ° 51 ′ 11.9 ″ n, 100 ° 21 ′ 48.8 ″ e, 1563m above sea levelThe coordinates of the release point of Gaoya hydrological station are: 39 ° 8 ′ 7.2 ″ n, 100 ° 23 ′ 59.0 ″ e, altitude, 1418mThe coordinates of the release point of a rou super station are: 38 ° 03 ′ 17.9 ″ n, 100 ° 27 ′ 28.1 ″ e, with an altitude of 2991m Measuring instruments: Vaisala wireless radiosonde rs92-sgp and GPS radiosonde of Beijing Changfeng surface acoustic wave company Measurement time: observation during aviation flight synchronization from June 29 to August 2, 2012. See Table 1 in the dataset for details.   Data content: atmospheric profile data of wind, temperature, humidity, pressure and other elements. The observation frequency is once in 2 seconds and the observation height is 10000-30000 meters. See Table 1 in the dataset for details
