三亚站中高层大气风场数据2014年

本数据集为三亚观测站观测得到的数据进行计算整理得到的数据结果。内容包括三亚地区中高层大气风场的纬向风（东西）、经向风（南北）和误差码，误差码为0的可信度较高，为1的可信度较低，建议使用时跳过。本数据集提供了我国区域空间环境地基观测的多层次、多参量数据集，在空间物理、地球物理等基础研究领域，国防和卫星导航定位等应用均有重要作用。可用于我国电离层、中高层大气和地磁等地区特性和变化的研究，地球各圈层耦合和动力过程研究，地球空间环境对太阳活动响应，空间天气现报和预报，有关参数经验模式建立，卫星定位导航等电离层电波修正等问题。观测站位于海南省三亚市东北方向的田独镇境内，距三亚市区20公里，在海南岛中线公路以西900米处，东距大茅村700米，南部为水库，西部和北部为山地。其位置如下，地理纬度： 18.4°N，地理经度：109.6°E ；海拔：52米。

This dataset is the processed and collated result of observational data from the Sanya Observatory. It includes the zonal wind (east-west direction) and meridional wind (north-south direction) of the middle and upper atmospheric wind field over the Sanya region, as well as error codes. An error code of 0 denotes high data reliability, while an error code of 1 denotes low reliability; it is recommended to exclude data with an error code of 1 during usage. This dataset provides a multi-level, multi-parameter ground-based observation dataset of China’s regional space environment, and plays a significant role in basic research fields such as space physics and geophysics, as well as applications including national defense and satellite navigation and positioning. It can be applied to studies on regional characteristics and variations of China’s ionosphere, middle and upper atmosphere, geomagnetism and other related fields; studies on coupling and dynamic processes among Earth’s various spheres; responses of Earth’s space environment to solar activity; real-time space weather monitoring and forecasting; establishment of empirical models for relevant parameters; and ionospheric radio wave correction for satellite positioning and navigation and other related issues. The observatory is situated in Tiandu Town, northeast of Sanya City, Hainan Province, 20 km from downtown Sanya, 900 meters west of the Hainan Island Central Highway, 700 meters east of Damao Village, with a reservoir to its south and mountains to its west and north. Its geographic parameters are as follows: geographic latitude 18.4°N, geographic longitude 109.6°E; elevation 52 meters.
