Recently, a new Multi-Angle Implementation of Atmospheric Correction (MAIAC) algorithm was developed for the MODerate Resolution Imaging Spectroradiometer (MODIS), which provides aerosol optical depth (AOD) at 1 km resolution. The relationship between MAIAC AOD and PM2.5 as measured by 84 EPA ground monitoring stations in the entire New England and the Harvard super site during 2002–2008 was in...

The newly released MODIS Collection 6 aerosol products have been widely used to evaluate fine particulate matter with a 10 km Dark Target aerosol optic depth (DT AOD) product, a new 3 km DT AOD product and an enhanced Deep Blue (DB) AOD product. However, the representativeness of MODIS AOD products under different air quality conditions remains unclear. In this study, we obtained all three type...

Strong seasonal variations in regional aerosol optical depth at 550 nm (AOD) and aerosol type were investigated over China’s Bohai Rim based upon six years’ worth of data from four sites. Aerosol loading was higher and particle sizes were larger in the spring and summer than in the autumn or winter in the region. The regional mean background AOD and Angstrom exponent (a) were 0.20 0.03 and 0.74...

Satellite-retrieved aerosol optical depth (AOD) has become an important predictor of ground-level particulate matter (PM) and greatly empowered air pollution research worldwide. We evaluated the AOD parameters included in the Collection 6 aerosol product of the Moderate Resolution Imaging Spectroradiometer (MODIS) for two key factors affecting their applications in air quality research—coverage...

The purpose of this study was to identifY if the Hmong of Dunn County, Wisconsin have risk factors for developing type 2 diabetes mellitus. Thirty-one subjects (17 males aod 14 females) from 18-60 years old participated in the study. Data was collected at the Dunn County Supplemental Nutrition Program for Women, lnfaots, aod Children, aod Hmong Stout Student Organization of University of Wiscon...

OBJECTIVE Simultaneously assess the relationship between the family support perception and the intensity of hopelessness, depression, and anxiety symptoms in alcohol or drug dependent (AOD) patients and in non-AOD dependent control group (CON). METHOD 60 patients who met the DSM-IV criteria for AOD dependence and 65 individuals with similar profile, but not dependent on AOD completed the Fami...

linical characteristics and testing results in those with and without HF at the time of their AoD. Those with CHF tended to resent in atypical fashion, and whereas CHF at the time of AoD id not appear to lead to inordinate delays in patient presentation, potential impact of CHF on time to recognition of AoD was oted, and CHF was an independent predictor of surgical delay. In ur data set, it is ...
