中亚平均风速分布图（2017）

中亚地区风速数据集，为tif格式。其空间范围涵盖里海在内的中亚五国地区，包括乌兹别克斯坦、哈萨克斯坦、土库曼斯坦、塔吉克斯坦和吉尔吉斯坦。该数据由GLDAS全球三小时同化数据提取获得。时间分辨率为3小时，空间分辨率为0.25°，时间范围为：2017年平均值。可以利用该数据进行中亚五国的大尺度输沙通量计算，进而估算沙丘的潜在移动速度等参数。该数据集可为中亚地区沙漠油气田与绿洲城镇风沙灾害评估提供数据支撑。

Central Asia Wind Speed Dataset is stored in TIFF format. Its spatial coverage encompasses the five Central Asian countries (Uzbekistan, Kazakhstan, Turkmenistan, Tajikistan and Kyrgyzstan) as well as the Caspian Sea region. This dataset is extracted from the 3-hourly assimilated data of the Global Land Data Assimilation System (GLDAS). It has a temporal resolution of 3 hours, a spatial resolution of 0.25°, and its temporal coverage corresponds to the 2017 annual average values. This dataset can be used to calculate the large-scale sediment transport flux in the five Central Asian countries, and further estimate parameters such as the potential migration velocity of sand dunes. It can provide data support for wind-sand disaster assessment of desert oil and gas fields and oasis towns in Central Asia.
