National Climate Assessment (NCA)

Dr. Daniel Tong of the Center for Spatial Information Science and Systems, GMU and his research partners recently received a new grant from NASA to develop a new climate indicator.
Dr. Tong serves as the principal investigator of this newly awarded project.

Detail This new NASA project has an ambitious goal to build a broad consensus of the dust trends, so that a baseline can be developed to watch for future dust anomaly. The scientists will use satellite sensors, ground monitors, and computer models to reveal not only the long-term trend, but also the climate forces behind it. The team includes the GMU Center for Spatial Information Science and System, dust scientists from University of Texas, NASA, National Oceanic and Atmospheric Administration (NOAA) and US Department of Agriculture (USDA).
This research is expected to provide important information for climate adaptation for a variety of user communities, including agriculture and soil conservation, air quality, public health, transportation and real estate investment in the impacted sectors. This project will initially focus on supporting the USDA and the soil conservation community, as USDA is the nation's leading force to combat and mitigate climate-related soil erosion. In the U.S., the loss of top soil has been estimated to cost $125 billon per year.
