Abstract:

The ecological crisis induced by the shrinkage of the Aral Sea constitutes a significant environmental challenge in Central Asia. To elucidate the evolving patterns of soil wind erosion in this region, the authors developed a Wind Erosion Modulus Dataset for the Aral Sea and Surrounding Regions in Central Asia (1990-2020) by employing multi-source geospatial data, including MODIS vegetation indices, ESA-CCI land cover data, SRTM elevation data, and ERA5-Land meteorological reanalysis data, based on the Revised Wind Erosion Equation (RWEQ) within the Google Earth Engine (GEE) platform. The dataset has a spatial resolution of 1 km, and a temporal resolution of one year. The validation against measured dust flux data from the Aral Sea Dust Monitoring Stations (2000-2005) demonstrates strong spatial agreement between simulated wind erosion intensity and field observations. It shows the dataset’s reliability in characterizing regional wind erosion dynamics. The dataset is archived in .tif format, and consists of 31 data files with data size of 260 MB (compressed into one file, 166 MB).
