DAQ has completed and overseen several research projects to better characterize the unique conditions in Clark County.  Multiple studies specifically addressed particulate matter, ozone, and carbon monoxide issues.  Other projects were focused on specific emission inventory categories such as paved road dust, consumer products, ozone precursors, and biogenic emissions.

Pollutant Specific Research	Description
Particulate Matter
Particulate Matter (PM10) Saturation Monitoring Study (2007)	A study to help understand the spatial distribution of PM10 and assess the adequacy of the existing Air Quality Monitoring Network to measure impacts.
An Inventory of Vacant Land Soil Stability and Unpaved Private Roads in the Las Vegas Valley Using Remote Sensing Imagery (2006)	A study to develop an inventory of native desert land, disturbed vacant land, stabilized vacant land, and private unpaved roads in the Las Vegas Valley using remote sensing technologies.
Las Vegas Valley Visibility and PM2.5 (2002)	A study conducted by the Desert Research Institute to determine the chemical composition of haze and fine particulate matter in southern Nevada.
Fugitive Dust and Other Source Contributions to PM10 in Nevada's Las Vegas Valley (1997)	This study was designed to better understand the source and nature of the elevated PM10 levels in the Las Vegas Valley.
Ozone
Fires, Asia, and Stratospheric Transport Las Vegas Ozone Study (FAST-LVOS) (2017)	This study builds on findings of the 2013 LVOS study to further assess the effects of wildland fires, Asian pollution, and stratospheric intrusions on surface ozone concentrations in Clark County, and the relative contribution of these processes to high ozone events compared to local ozone production and regional transport from Southern California. For further information about this study, please visit the NOAA website at: https://www.esrl.noaa.gov/csd/projects/fastlvos/.
Las Vegas Ozone Study(LVOS)  (2013)	Study to assess the seasonal influence of stratosphere-to-troposphere transport (STT) and long-range transport from Asia (AS) on surface ozone concentrations in Clark County. For further information about this study, please visit the NOAA website at: https://www.esrl.noaa.gov/csd/projects/lvos/.
Southwest Desert/Las Vegas Transport Study (2008)	Study of the mechanisms and impact of pollutant transport into southern Nevada through enhanced monitoring of ozone air quality and meteorology at key locations during the 2007 ozone season.
Ozone Characterization Study (2006)	Study to characterize ozone, its precursors, and transport during high-ozone events.
Clark County Regional Ozone & Precursor Study (2006)	Program to collect data needed for the characterization and understanding of tropospheric ozone in Clark County.
Carbon Monoxide
Carbon Monoxide Saturation Study (2002)	A detailed assessment of CO concentrations in the Las Vegas Valley.
Evaluation of Effectiveness of I&M Program (2002)	This study was conducted to determine an effectiveness rate for the Vehicle Inspection and Maintenance Program in Clark County.

 

Emissions inventory Research	Project
Biogenics
Biogenics Emissions Inventory for Clark County, NV (2006)	Study to quantify biological emissions from vegetation and land use in Clark County.
Biogenic VOC Emission Inventory Improvement Project (2006)	Study to improve the accuracy of the biogenic emissions inventory for Clark County.
VOC
Analysis From the Clark County Regional Ozone Precursor Studies (2007)	Volatile Organic Compounds (VOC) data for Hazardous Air Pollutants
Clark County Consumer and Commercial Products Emissions Inventory (2005)	Study to quantify volatile organic compound emissions from consumer products in Clark County and recommend potential control measures.
Particulate Matter
Clark County Paved-Road Mobile Sampling Technologies Studies (2008)	Studies conducted by the DAQ, the Desert Research Institute of Nevada, University of California at Riverside, California and the University of Nevada at Las Vegas on Paved Road Dust Emission Studies in Support of Mobile Monitoring Technologies. Studies compare USEPA AP-42 silt sampling methods with mobile sampling technologies for characterizing entrainable paved-road dust emissions.
Remote Sensing of Gaseous and Particulate Emissions from Onroad Sources (2002)	A study conducted by the Desert Research Institute using remote sensing technologies for use in evaluating emissions from onroad vehicles.
Wind Tunnel Studies to Establish High Wind Threshholds
Clark County Wind Tunnel Study Section 1 (2000)	Estimation of Valley-Wide PM10 emissions using UNLV 1995 wind tunnel measurements, revised vacant land classifications, and GIS-based mapping of vacant lands.
Clark County Wind Tunnel Study Section 2 (2000)	Estimation of Valley-Wide PM10 emissions using UNLV 1995 wind tunnel-derived emission factors, 1998-1999 emission factors, revised vacant land classifications, and GIS-based mapping of vacant lands.
Clark County Wind Tunnel Study Section 3 (2001)	Estimation of PM10 vacant land emission factors for Unstable, Stable and Stabilized lands using data from 1995 and 1998-1999 UNLV wind tunnel studies of vacant and dust-suppressant treated lands.
Clark County Wind Tunnel Study Section 4 (2006)	Refined PM10 Aeolian Emission Factors for native Desert and Disturbed Vacant land Areas for 2004 – Final Report.
Clark County Wind Tunnel Study Section 5 (2006)	Addendum to 2004 Wind Tunnel Study – PM10 Milestone Achievement Report.
