Minimum Aerosol Layer Detection Sensitivities And Their Subsequent Impacts On Aerosol Optical Thickness Retrievals In Calipso Level 2 Data Products, Travis D. Toth, James R. Campbell, Jeffrey S. Reid, Jason L. Tackett, Mark A. Vaughan, Jianglong Zhang, Jared W. Marquis

Atmospheric Sciences Faculty Publications

Due to instrument sensitivities and algorithm detection limits, level 2 (L2) Cloud-Aerosol Lidar with Orthogonal Polarization (CALIOP) 532 nm aerosol extinction profile retrievals are often populated with retrieval fill values (RFVs), which indicate the absence of detectable levels of aerosol within the profile. In this study, using 4 years (2007– 2008 and 2010–2011) of CALIOP version 3 L2 aerosol data, the occurrence frequency of daytime CALIOP profiles containing all RFVs (all-RFV profiles) is studied. In the CALIOP data products, the aerosol optical thickness (AOT) of any all-RFV profile is reported as being zero, which may introduce a bias in CALIOP-based …

Decreased Mortality Of Pulmonary Arterial Hypertension In Duchenne Muscular Dystrophy And Down Syndrome, Mitchell Volin

Physician Assistant Scholarly Project Posters

The genetic cause of significant disorders like Down syndrome (DS) and Duchenne muscular dystrophy (DMD) is well documented. Pulmonary arterial hypertension (PAH), a co-morbid condition, is tied to mortality among these groups. Individuals with the ability to communicate their symptoms and actively participate in treatment are at an advantage with subsequent benefit. DS and DMD significantly decrease physical ability and communication capacity. Genetic research has allowed for earlier identification of, or predisposition for, the development of PAH. Work has also progressed toward manipulation at the genetic level to decrease the severity and even eradicate the cardiopulmonary disorder. This information is …
