Statistical variability of top of atmosphere cloud-free shortwave aerosol radiative effect
atmosphere cloud-free shortwave aerosol radiative effect
2008/12/11
The statistical variability of globally averaged MODIS aerosol optical thickness at 0.55 μm (AOT) and top of atmosphere CERES cloud-free shortwave radiative effect (SWRE) is presented. Statistical var...
Modelling the global tropospheric ozone budget: exploring the variability in current models
global tropospheric ozone budget variability current model
2008/12/10
What are the largest uncertainties in modelling ozone in the troposphere, and how do they affect the calculated ozone budget? Published chemistry-transport model studies of tropospheric ozone differ s...
Interannual variability of the stratospheric wave driving during northern winter
stratospheric wave driving northern winter
2008/12/10
The strength of the stratospheric wave driving during northern winter is often quantified by the January–February mean poleward eddy heat flux at 100 hPa, averaged over 40°–80° N (or a similar area an...
Size-segregated mass distributions of aerosols over Eastern Mediterranean: seasonal variability and comparison with AERONET columnar size-distributions
aerosols Eastern Mediterranean AERONET columnar
2008/12/10
This work provides long-term (2004–2006) size segregated measurements of aerosol mass at a remote coastal station in the southern Europe, with the use of size-selective samplings (SDI impactor). Seven...
On the diurnal variability of particle properties related to light absorbing carbon in Mexico City
particle properties carbon Mexico City
2008/12/10
The mass of light absorbing carbon (LAC) in individual, internally mixed aerosol particles was measured with the Single Particle Soot Photometer (SP2) in April of 2003 and 2005 and evaluated with resp...
Observed and Interpolated Precipitation Trends and Variability in the Yangtze Catchment Area
China Yangtze River climate change precipitation trend analysis
2008/12/2
Precipitation trends in China with special emphasis on the Yangtze catchment area have been analysed. Significant positive and negative trends for the second half of last century have been detected fo...
On the variability of the Ring effect in the near ultraviolet: understanding the role of aerosols and multiple scattering
ultraviolet aerosols multiple scattering
2008/12/1
The "filling-in" (FI) of Fraunhofer lines, often referred to as the Ring effect, was examined using measurements of near ultraviolet sunlight scattered from the zenith sky above Boulder, Colorado duri...
Seasonal variability of measured ozone production efficiencies in the lower free troposphere of Central Europe
measured ozone lower free troposphere Central Europe
2008/11/27
In this study we present the seasonal variability of ozone production efficiencies (EN), defined as the net number of ozone molecules produced per molecule of nitrogen oxides (nitrogen oxide (NO) + ni...
A century of temperature variability in Lake Superior
temperature variability Lake Superior
2014/4/21
A 100-yr-long time series of water temperature measured just downstream of Lake Superior is used to produce proxy time series of open-lake temperature. This analysis suggests that open-water Lake Supe...
Interpreting the variability of space-borne CO2 column-averaged volume mixing ratios over North America using a chemistry transport model
space-borne CO2 North America chemistry transport model
2008/11/21
We use the GEOS-Chem chemistry transport model to interpret the sources and sinks of CO2 that determine variability of column-averaged volume mixing ratios (CVMRs), as observed by the SCIAMACHY satell...
Variability of cirrus clouds in a convective outflow during the Hibiscus campaign
cirrus clouds convective outflow Hibiscus campaign
2008/11/14
Light-weight microlidar and water vapour measurements were taken on-board a stratospheric balloon during the HIBISCUS 2004 campaign, held in Bauru, Brazil (49° W, 22° S). Cirrus clouds were observed ...

UV variability in Moscow according to long-term UV measurements and reconstruction model
UV Moscow
2008/11/11
Long-term measurements of erythemally weighted UV irradiance (Qer) have been analyzed for the 1999–2006 period as well as UV variability according to a reconstruction model since 1968. The estimates ...
