中亚平均输沙势分布（2017）

中亚地区2017年输沙势数据集，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。此输沙势为绝对输势，即各个方向的输沙通量的综合，不考虑输沙势的方向。该数据由GLDAS全球三小时同化数据提取计算获得。时间分辨率为月，空间分辨率为0.25°，时间范围为2017年。该数据可以作为沙尘传输模型的重要参数输入，也可用于评估中亚五国沙通量的总体分布情况。该数据集可作为风沙灾害评估的重要参考数据。

This is a 2017 absolute sediment transport potential dataset over Central Asia, stored in TIFF format. Its spatial coverage encompasses the five Central Asian countries including the Caspian Sea region, namely Uzbekistan, Kazakhstan, Turkmenistan, Tajikistan and Kyrgyzstan. The absolute sediment transport potential here refers to the comprehensive sum of sediment fluxes across all directions, without considering the directional attribute of sediment transport potential. This dataset is extracted and calculated from the 3-hourly Global Land Data Assimilation System (GLDAS) global assimilation data. It has a monthly temporal resolution and a 0.25° spatial resolution, covering the full year of 2017. This dataset can serve as an important parameter input for dust transport models, be used to evaluate the overall distribution of sand flux in the five Central Asian countries, and act as a critical reference data for wind-sand disaster assessment.
