Contribution of Atmospheric Diffusion Conditions to the Recent Improvement in Air Quality in China
This study analyzed hourly mass concentration observations of PM2.5 (particulate matters with diameter less than 2.5 μm) at 512 stations in China from December 2013 to May 2015. We found that the mean concentrations of PM2.5 during the winter and spring of 2015 Dec. 2014 to Feb. 2015 and Mar. 2015 to May 2015) decreased by 20% and 14% compared to the previous year, respectively. Hazardous air-q...
متن کاملTransgenerational phenotypic plasticity under future atmospheric conditions
Edward B. Mondor,* Michelle N. Tremblay and Richard L. Lindroth Department of Entomology, University of Wisconsin, Madison, WI 53706, USA *Correspondence: E-mail: [email protected] Abstract Organisms often exhibit transgenerational phenotypic changes in response to an increased risk of parasitism or predation. Shifts in global atmospheric composition could modify these phenotypic effec...
متن کاملComparison of three diffusion encoding schemes for cardiac imaging under free breathing conditions.
Background Diffusion cardiac imaging has been challenging due to respiratory and heart motion. Recent developments in cardiac diffusion imaging proposed more robust spin echoes encoding scheme, like Acceleration Motion Correction(AMC)(1), to tackle cardiac motion. In addition, free breathing acquisition with prospective motion correction like slice following technique (2) has been shown to redu...
متن کاملTurbulence Structure of the Atmospheric Boundary Layer in Stable Conditions
Data from SABLES98 experimental campaign have been used in order to study the influence of stability (from weak to strong stratification) on the flux-profile relationships for momentum and heat: φm and φh. Standard instrumentation, 14 thermocouples and 3 sonic anemometers at three levels (5.8, 13.5 and 32 m) were available from 10 to 28 September 1998 and calculations are done in order to extra...
متن کاملStable Boundary Layer Mixing in a Vertical Diffusion Scheme
The YSU PBL scheme is a revised vertical diffusion package with a nonlocal turbulent mixing coefficient in the planetary boundary layer (PBL). Based on the study of Noh et al (2004, BLM) and accumulated results of the behavior of the Hong and Pan algorithm, a revised vertical diffusion algorithm that is suitable for weather forecasting and climate prediction models is developed. The major ingre...
