A Linear Regression of Differential PWV Calibration Model to Improve the Accuracy of MODIS NIR All-Weather PWV Products Based on Ground-Based GPS PWV Data

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022
Precipitable water vapor (PWV) products derived from the near-infrared (NIR) channels of the Moderate Resolution Imaging Spectroradiometer (MODIS) instruments, onboard Aqua and Terra satellites, were calibrated using a linear differential PWV (LinearDP ...

COMPARISON OF GNSS PWV AND ERA5-DERIVED PWV BASED ON GNSS PWV IN HONG KONG, CHINA [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2020
Water vapor is the most abundant atmospheric gas, and it plays a vital role in the evolution of the Earth's climate. Precipitable water vapor (PWV) is a key factor in monitoring the climate and hydrological cycle.

Blood Pressure Mediates the Association Between Carotid-Femoral Pulse Wave Velocity and Basal Ganglia Enlarged Perivascular Spaces: A Community-Based Cross-Sectional Study. [PDF]

J Clin Hypertens (Greenwich)
ABSTRACT Although carotid‐femoral pulse wave velocity (cf‐PWV) is the non‐invasive gold standard for assessing aortic stiffness, evidence linking cf‐PWV to basal ganglia enlarged perivascular spaces (BG‐EPVS) in the general population is limited. We aimed to evaluate this association and quantify the mediating role of blood pressure (BP) in community ...

Non-Invasive Assessment of Endothelial Dysfunction and Arterial Stiffness in Fontan Circulation. [PDF]

Eur J Clin Invest
The Fontan procedure is the definitive treatment for complex congenital heart disease, creating a circulation without a subpulmonary ventricle. This altered hemodynamic state negatively affects endothelial function, contributing to progressive organ dysfunction and long‐term morbidity.

Multidomain Arterial Afterload and Left Atrial-Left Ventricular Coupling in Hypertensive Phenotypes. [PDF]

J Clin Hypertens (Greenwich)
ABSTRACT Brachial blood pressure may not fully reflect the multidimensional arterial load associated with left atrial–left ventricular (LA–LV) coupling. In this cross‐sectional study, we examined local carotid pulse wave velocity (PWV), cuff‐derived arterial pressure–volume index (API), and arterial velocity–pulse index (AVI), separately and as a ...

Average Real Variability Is an Independent Predictor of Increased Arterial Stiffness Assessed by Pulse Wave Velocity. [PDF]

J Clin Hypertens (Greenwich)
ABSTRACT Blood pressure variability (BPV) is an established cardiovascular risk factor associated with target organ damage beyond mean blood pressure levels. Arterial stiffness, assessed by carotid–femoral pulse wave velocity (cfPWV), represents an early manifestation of hypertension and an independent predictor of cardiovascular events.
