SERDP project SI-1399 carried out an empirically-based study using in situ measurements to characterize and quantify dust emissions from unique Department of Defense sources operating during testing and training maneuvers on U.S. military installations. This project focused on developing an understanding of the dust emission process and strength of these emissions for artillery backblast on improved gun-sites surface treated with dust palliatives, tracked and wheeled vehicles travelling on unpaved surfaces, and rotary-winged aircraft travelling close to desert surfaces. Based on the measured dust emissions from these sources the greatest amount of emissions is from tracked and wheeled vehicles due to their high emission rates and frequency of use. Dust emissions from both artillery backblast and rotary-winged aircraft are representative of only minor contributing sources in the overall attribution of airborne particulates to DoD sources. In partnership with SI-1400 a hybrid measurement system for estimating fugitive emissions of dust was also tested, which combined elements of optical remote sensing and in situ measurements. This testing showed that such a system will allow for the development and eventual deployment of other open path extinction measurements tools such as LIDAR or digital cameras, which can be used to develop fugitive PM emission factors. The dust emission relationships and defined emission factors developed as part of this project were incorporated into the DUSTRAN model that can be used to forecast and hind-cast dust emissions based on testing and training scenarios involving these source types with knowledge of the meteorology.
