Responses of the lower thermosphere to the 9-day and 13.5-day oscillations of recurrent geomagnetic activity and solar activity have been investigated using the temperature data observed by TIMED/ SABER in 2002-2007(declining phase of solar cycle 23).The observational results show that the9-day and 13.5-day temperature variations with zonal wavenumber 0 in the height range 100-120 km are more strongly correlated with the recurrent geomagnetic activity than solar EUV *** 9-day and13.5-day temperature oscillations in the lower thermosphere have greater amplitudes at high latitudes than those at low latitudes;these responses also have larger amplitudes at higher altitudes from 100 km to 120 ***,the 9-day and 13.5-day temperature variations can penetrate down to 105 *** responses to recurrent geomagnetic activity are different in the two *** TIME-GCM(National Center for Atmospheric Research-Thermosphere Ionosphere Mesosphere Electrodynamics Model) simulations are consistent with the observations;therefore it was used to investigate the different effects of the multiday periodic oscillations of recurrent geomagnetic activity and solar EUV(Extreme Ultraviolet) radiance on the periodic responses of the lower *** find that recurrent geomagnetic activity is the main cause of the 9-day and 13.5-day variations in the lower thermosphere.

A method for quantifying bias in modeled concentrations and source impacts for secondary particulate matter

引用

Frontiers of Environmental Science & Engineering 2016年第5期10卷 153-164页

作者： Cesunica E. lvey Heather A. Holmes Yongtao Hu james A. Muiholland Armistead G. russell School of Civil and Environmental Engineering Georgia Institute of Technology 311 Ferst Drive Atlanta GA 30332 USA Department of Physics University of Nevada Reno 1664 N Virginia St Reno NV 89557 USA

Community Multi-Scale Air Quality （CMAQ） estimates of sulfates, nitrates, ammonium, and organic carbon are highly influenced by uncertainties in modeled secondary formation processes, such as chemical mechanisms, volatilization, and condensation rates. These compounds constitute the majority ofPM2.5 mass, and reducing bias in estimated concentrations has benefits for policy measures and epidemiological studies. In this work, a method for adjusting source impacts on secondary species is developed that provides estimates of source contributions and reduces bias in modeled concentrations compared to observations. The bias correction adjusts concentrations and source impacts based on the difference between modeled concentrations and observations while taking into account uncertainties at the location of interest; and it is applied both spatially and temporally. We apply the method over the US for 2006. The mean bias for initial CMAQ concentrations compared to observations is -0.28 （OC）, 0.11 （NO3）, 0.05 （NH4）, and -0.08 （SO4）. The normalized mean bias in modeled concentrations compared to observations was effectively zero for OC, NO3, NH4, and SO4 after applying the secondary bias correction. Ten-fold cross-validation was conducted to determine the performance of the spatial application of the bias correction. Cross-validation performance was favorable; correlation coefficients were greater than 0.69 for all species when comparing observations and concentrations based on kriged correction factors. The methods presented here address model uncertainties by improving simulated concentrations and source impacts of secondary particulate matter through data assimilation. Secondary-adjusted concentrations and source impacts from 20 emissions sources are generated for 2006 over continental US.
