Fugitive Dust Emissions From Agriculture

The dust generated from field preparations activities can contribute to particulate matter pollution loads. The UCONN LIDAR has been used in New England corn fields and coten fields in teh southwestern United States to gain a more complete understanding of the dust plume dynamics and off site emissions.
               
     
Field deployment of air samplers near the source allows for characterization of particle sizes and source strength concentrations. These measurements are used in both model development and as a calibration for lidar measured concentrations.
               
             
Horizontal Lidar scans are taken in approximately 6 seconds and all for a cross section of the plume above the field to be examined.      
             
           
  Individual slices can be combined for three dimensional images of plumes to be examined.
