Paper Abstract

AGLITE is a multiwavelength lidar developed for Agricultural Research Service of the United States Department of Agriculture and its program on particle emissions from animal production facilities. The lidar transmission system is a pulsed Nd:YAG laser (355, 532, 1064 nm) operating at a pulse rate of 10 kHz. We analyze and model lidar backscatter and extinction coefficients to extract aerosol physical properties. All wavelength channels operate simultaneously, day or night, using photon counting and high speed data acquisition. The lidar housing is a transportable trailer suitable for all-weather operation at any accessible site. We direct the laser and telescope field of views to targets of interest in both azimuth and elevation. Arrays of particle samplers and turbulence detectors were also used by colleagues specializing in those fields and are compared with the lidar data. The value of multiwavelength, eyesafe lidars for agricultural aerosol measurements has been confirmed by the successful operation of AGLITE. In this paper, we demonstrate the ability of the lidar system to quantitatively characterize particulate emissions as mass concentration fields applicable for USEPA regulations. The combination of lidar with point characterization information allows the development of 3-D distributions of standard USEPA mass concentration fractions (PM10, PM2.5, and other interesting groupings such as PM10-PM2.5 and PM1). Lidar measurements are also focused on air motion as seen by long duration scans of the farm region. We demonstrate the ability to use "standoff" lidar methods to determine the movement and concentrations of emissions over an entire agricultural facility.
