Research Project: SIMULATING WIND EROSION INDUCED PARTICULATE EMISSION AND TRANSPORT
2011 Annual Report


1a.Objectives (from AD-416)
Combine the Erosion submodel of the Wind Erosion Prediction System (WEPS) coupled with the Meteorology, Chemistry, and Climate Model (MCCM) to simulate emission and regional transport of fine dust from agricultural fields.


1b.Approach (from AD-416)
Research studies will be conducted at both locations on developing systems to predict the generation and dispersion of fine particulates from agricultural lands. Research will be facilitated by exchanges of methodology for analysis and expertise in predicting regional fate of particulates generated from agricultural lands.


3.Progress Report

ARS-EWERU scientist participated in collaborative research with scientists at the Center for Atmospheric Science at the National Autonomous University of Mexico (UNAM). Using the Wind Erosion Prediction System (WEPS) erosion submodel and the Multiscale Climate and Chemistry Model (MCCM) air quality model, a study of the effect of wind eroded soil on fine dust production and movement around Mexico City was published. The importance of wind erosion from the dry Lake of Texcoco and agricultural lands to the East and South-East of Mexico City on urban air quality, its genesis, morphology, and regional implications was established. The combined erosion and air quality model described provide a useful computational tool to study the wind erosion phenomenon, its sources, and impact on urban regions. A peer reviewed journal paper has been published on the work. Methods of monitoring this project included, discussing project plans, reviewing program goals and accomplishments with the Cooperator’s PI at ARS and collaborator facilities; stakeholders meetings; by teleconference, e-mail and other types of written correspondence as well as face-face-meetings; providing technical advice.
