We analyse the critical surface albedo (CSA) and its implications to aerosol remote sensing. CSA is defined as the surface albedo, where the reflectance at top-ofatmosphere (TOA) does not depend on aerosol optical depth (AOD). AOD retrievals are therefore inaccurate at the CSA. The CSA is obtained by derivatives of the TOA reflectance with respect to AOD using a radiative transfer code. We pres...

Hypertension accelerates the age-associated increase in aortic root diameter (AoD), likely because of chronically elevated distending pressures. However, the pulsatile component of blood pressure may have a different relationship with AoD. We sought to assess the relationship between AoD and pulse pressure (PP) while accounting for left ventricular and central arterial structural and functional...

The performance and application of AOD products from the Moderate Resolution Imaging Spectroradiometer (MODIS) are studied by comparing with the AOD derived from the ground-based Doppler LIDAR inside the Hong Kong International Airport (HKIA). The backscattered power data of the LIDAR are used to determine the extinction coefficient profile, from which the AOD is calculated. The AOD determined ...

This manuscript compares statistics of the CALIPSO derived aerosol optical depth (AOD) above low level clouds to that in cloud free scenes. Results are presented for both daytime and nighttime retrievals of AOD. The work illustrates that there are some differences in the AOD above low cloud and the AOD in clear skies in the daytime retrievals e.g. over the southeast Atlantic in SON. These are h...

• Rates of risky consumption of alcohol and other drugs (AOD) and related harms among Indigenous Australians are generally twice those in the non-Indigenous population. • High levels of AOD-related harm among Indigenous Australians are both a consequence of, and contribute to, the health and social gap between them and non-Indigenous Australians. • Reduction of harmful AOD use must include broa...

Attention deficit hyperactivity disorder (ADHD) is a childhood mental health disorder that can lead to alcohol and other drug (AOD)-related problems if it persists into adolescence and adulthood. Several findings suggest that ADHD contributes to the development of AOD use disorders. ADHD generally precedes alcohol use and is correlated with developmentally inappropriate levels of alcohol use or...

Abdominal aortic aneurysm (AAA) and aortic occlusive disease (AOD) represent common causes of morbidity and mortality in elderly populations which were previously believed to have common aetiologies. The aim of this study was to assess the gene expression in human AAA and AOD. We performed microarrays using aortic specimen obtained from 20 patients with small AAAs (≤ 55mm), 29 patients with lar...

BACKGROUND To describe patterns of alcohol and other drug (AOD) use risk and adolescent reported primary care (PC) screening and intervention, and examine associations of AOD risk and mental health with reported care received. METHODS We analyzed data from cross-sectional surveys collected from April 3, 2013 to November 24, 2015 from 1279 diverse adolescents ages 12-18 who reported visiting a...
