[1] We use an ensemble of satellite (MODIS), aircraft, and ground‐based aerosol observations during the ICARTT field campaign over eastern North America in summer 2004 to (1) examine the consistency between different aerosol measurements, (2) evaluate a new retrieval of aerosol optical depths (AODs) and inferred surface aerosol concentrations (PM2.5) from the MODIS satellite instrument, and (3)...

Economic research contributes to our understanding of alcohol use and the prevention and treatment of alcohol-related problems in several ways. This article reviews three areas in which the tools of economic analysis have produced significant insights in recent years. First, economic researchers have analyzed the effects of beverage prices and taxation on alcohol consumption and on adverse cons...

We investigate the effects of aerosol optical depth (AOD), single scattering albedo (SSA), aerosol peak height (APH), measurement geometry (solar zenith angle (SZA) and viewing zenith angle (VZA)), relative azimuth angle, and surface reflectance on the accuracy of NO2 slant column density using synthetic radiance. High AOD and APH are found to decrease NO2 SCD retrieval accuracy. In moderately ...

In 2011, the Australian National Health and Medical Research Council (NHMRC) initiated an inquiry to determine whether there is a need for expanded ethical guidance in the form of a discrete guidance document for alcohol and other drug (AOD) research. An issues paper was developed to frame the inquiry. AOD researchers, Human Research Ethics Committees and others were invited to discuss whether ...

OBJECTIVE This paper explores the association between work intensity, alcohol and/or other drug (AOD) use, and related risk factors and consequences among an at-risk youth sample that has received a first-time AOD offense. This study extends previous research focused primarily on school-based samples. METHOD We examined the association between work intensity, AOD use, AOD-related consequences...

Aerosol Optical Depth (AOD), recognized as one of the most important quantities in understanding and predicting the Earth’s climate, is estimated daily on a global scale by several Earth-observing satellite instruments. Each instrument has different coverage and sensitivity to atmospheric and surface conditions, and, as a result, the quality of AOD estimated by different instruments varies acro...

The fine-mode fraction (FMF) of aerosol optical depth (AOD) is a key optical parameter that represents the proportion of fine particles relative to total aerosols in the atmosphere. However, in comparison to ground-based measurements, the FMF is still difficult to retrieve from satellite observations, as attempted by a Moderate-resolution Imaging Spectroradiometer (MODIS) algorithm. In this pap...

OBJECTIVE The study aimed to identify gender differences in barriers to alcohol and other drug (AOD) treatment use among disadvantaged communities in Cape Town, South Africa. The Behavioral Model of Health Services Utilization was used as an analytic framework. METHOD A case-control design was used to compare 434 individuals with AOD problems from disadvantaged communities who had accessed tr...

The high resolution (375m) of the Visible Infrared Imaging Radiometer Suite on board the Suomi National Polar-Orbiting Partnership satellite allows retrieving relatively accurately the vertical evolution of convective cloud drop effective radius (re) with height or temperature. A tight relationship is found over SE Asia and the adjacent seas during summer between the cloud-free aerosol optical ...
