This work is an extended evaluation of near-surface ozone as part of the global reanalysis of atmospheric composition, produced within the European-funded project MACC (Monitoring Atmospheric Composit...
Update of the Chronology of Natural Signals in the Near-Surface Mean Global Temperature Record and the Southern Oscillation Index
Climate Variability Southern Oscillation Index ENSO
2013/3/11
Time series for the Southern Oscillation Index and mean global near surface temperature anomalies are compared for the 1950 to 2012 period using recently released HadCRU4 data. The method avoids a foc...
Characteristics of the Near-Surface Boundary Layer within a Mountain Valley during Winter
Winter Near-Surface Boundary Layer Characteristics
2014/4/3
Within mountainous regions, estimating the exchange of sensible heat and water vapor between the surface
and the atmosphere is an important but inexact endeavor. Measurements of the turbulence charac...
Gyroscopic Pumping in the Solar Near-Surface Shear Layer
Gyroscopic Pumping Solar Near-Surface
2011/9/29
We use global and local helioseismic inversions to explore the prevailing dynamical balances in the solar Near-Surface Shear Layer (NSSL). The differential rotation and meridional circulation are inti...
Errors of Estimating Near-Surface Q-A statistical Approach
Q Near Surface Spectral Ratio Seismic Statistical Errors
2013/3/6
Although various estimating methods have been developed for measuring Q from near-surface seismic data, less thought has been given to the accuracy of Q obtained. The errors of Q depend on the ways of...
Detecting the influence of fossil fuel and bio-fuel black carbon aerosols on near surface temperature changes
fossil fuel bio-fuel black carbon aerosols surface temperature
2011/2/24
Past research has shown that the dominant influence on recent global climate changes is from anthropogenic greenhouse gas increases with implications for future increases in global temperatures. One m...
Decadal regional air quality simulations over Europe in present climate: near surface ozone sensitivity to external meteorological forcing
Decadal regional air quality Europe surface ozone external meteorological forcing
2010/12/28
Regional climate-air quality decadal simulations over Europe were carried out with the RegCM3/CAMx modeling system for the time slice 1991–2000, in order to study the impact of different meteorologica...
An Overview of Surface Conditions in Numerical Simulations of Dust Devils and the Consequent Near-surface Air Flow Fields
Dust devil Convection Large eddy simulation (LES) Vortices Surface friction
2016/3/29
Dust devils are generally attributed to the near-surface conditions, usually the composite actions of the surface
parameters, such as heat flux, wind shear and surface friction. Dust devil scale (DD-...
