Outline of Final Research Achievements

To find and monitor dust source regions, a semi-real-time dust erodibility map was developed based on MODIS satellite data that focuses particularly on the threshold wind speed in a target area of northeast Asia including China and Mongolia (35°-50°N, 75°-120°E). The mapping system incorporates satellite data on snow cover, areas of frozen soil, surface soil water content, and vegetation cover.
Satellite Image Retrieval and Visualizing Sub-System (SIRVS) is software designed to search, visualize, analyze and download the high-level products produced by the Global Satellite Data, and opened to the public. Products are threshold wind speed, vegetation cover, NDVI, cloud mask, snow mask, reflectivity of 7 bands, SbAI, and soil frozen mask.
