Relationship between Spatial and Temporal “Drought Memory” on Dust Sources in Two Ecoregions of the USA
Description
These datasets include the United States Drought Monitor (USDM) data (https://droughtmonitor.unl.edu/Data/GISData.aspx) and dust storm source points (https://data.mendeley.com/datasets/6f8nyyr6n9/1) developed from NASA MODIS Terra and Aqua imagery over the Chihuahuan Desert and Southern Great Plains covering Texas, New Mexico, and Oklahoma. The "United_States_Drought_Monitor_Raw" data indicates the United States Drought Monitor data in its raw format after downloading from the United States Drought Monitor website. The "United_States_Drought_Monitor_Processed" represents the United States Drought Monitor data after converted to raster file and clipped to the study area. The "Dust_Storm_Source_Points_Processed" represents the dust storm source points and the associated drought intensity in terms of space and time. The codes also provided here. The "Code_Used_to_Convert_Polygon_to_Raster" is used to convert the USDM images in shape files of polygon into raster images. The "Code_Used_to_Clip_Rastar_Images" is used to clip the raster images using the shapefile of the study area. The "Code_Used_to_Treat_NoData" is used to treat the "NoData" in the clipped raster images. The "Code_Used_to_Process_and_Map_USDM_Data" is used to process and map the USDM raster images. The "Code_Used_to_Plot_USDM_Linked_to_Dust_Points" is used to map the USDM data associated with the dust storm source points.
