Research Project: Enhance NCA Dust Indicator with NASA Earth Science Data and USDA Wind Erosion Assessment

Location: Wind Erosion and Water Conservation Research

Project Number: 3096-13000-009-03-I
Project Type: Interagency Reimbursable Agreement

Start Date: Oct 1, 2015
End Date: Mar 31, 2019

Objective:
To prove the concept that black sky albedo as measured with MODIS band MCD43A3 can be used as a proxy for plant lateral coverage and that temporal fluctuations will be coincident with the historic atmospheric dust record. Further that this proxy for lateral cover can be coupled with USDA-NRCS soil mapping databases of similar resolution to provide constantly updating maps of wind erosion and dust emission hazard that can be used to adjust surface management and mitigate the hazards of wind erosion and fugitive dust.

Approach:
Dr. Van Pelt will be a Co-I and Dr. Zobeck will be a collaborator on this project. They will advise on several key questions relevant to USDA soil conservation mission and climate adaptation strategy and on the selection of key USDA soils databases used to relate soils to dust emissions for the proposed dust indicator database to help build community consensus on the trend in soil wind erosion in the United States. In addition, they will advise on specific parameters (and NASA satellite and model data) that will be identified to develop proof of concepts of similar parameters proposed in the USDA soil-based rangeland dust model development and create a framework for “upscaling” USDA wind erosion assessments to inform the National Climate Assessment. Dr. Van Pelt will work with Co-I Gill and a graduate student to integrate and test proof-of-concepts, NASA data and tools to conduct and improve USDA rangeland soil erosion. He will serve as the USDA liaison with this proposed NCA project. Drs. Van Pelt and Zobeck will also contribute to the interpretation and synthesis of the results and to their publication in peer-reviewed literature.
