Dust Storm Dataset

The dust storm dataset is produced from a regional climate model WRF-NMM (WRF: Weather Research and Forecasting, NMM: Nonhydrostatic Mesoscale Model; Huang et al. 2013). It is about 390M in size. The “dust” dataset contains the information of dust dry deposition load (μg/m2), dust wet deposition (μg/m2), total dust load (μg/m2), and surface dust concentration of PM10 aerosols (μg/m3) at four dimensions: latitude, longitude, time, and pressure. Scientists can exploit our remote visualization system to interactively examine the spatiotemporal variations of dust load at different pressure levels.

Atmospheric Flow Dataset

The atmospheric flow dataset is generated by the Dust REgional Atmospheric Model (DREAM) (Nickovic et al. 2001). The dataset was a result of a 72-hour dust condition simulation, from July 1st to July 4th, 2014. The simulation area is located in the Southwestern United States with a resolution of 0.027 degree (about 33km). The “flow” dataset contains the information of atmospheric conditions (e.g. precipitation, wind speed and direction), land surface conditions (e.g. soil moisture and temperature), and dust conditions (e.g. dust concentration, dust load).
