Temporal variation of NO, NO2, SO2, SPM (suspended particulate matter), and O-3 were measured at a high altitude station in the northwestern part of Turkey. The long- and short-term trends in the concentrations of measured parameters were investigated to understand sources contributing to the observed concentrations of these pollutants. Higher concentrations of O-3 during summer months were consistent with higher photochemical production with increased solar flux. Seasonal patterns observed in other parameters were consistent with their source strengths during different periods of the year. O-3 showed a peak at approximately 3 pm, together with SO2 and NO2. SPM, on the other hand, showed a different diurnal pattern with a maximum concentration occurring during night hours. The main sources of O-3, SO2, and NO2 on Mt. Uludag were found to be transported from the town of Bursa and from a nearby ski resort. The vehicular activities on the road which connects the town of Bursa to the ski resort are also an observable source of O-3 and its precursors, but not of SO2 and SPM. High concentrations of O-3 were observed during night hours. Unlike daytime peaks, these peaks were sporadic and did not correlate with the SO2 and NO2. These night-time O-3 concentrations were suspected to be due to injection from the stratosphere.

Measurement of NOx, SO2, SPM and O3, at a high altitude station in the northwestern Turkey
Tuncel, Semra; Baykal, Abdülhadi; Tuncel, Süleyman Gürdal; Özer, Ulviye (1994-01-01)
Temporal variation of NO, NO2, SO2, SPM (suspended particulate matter), and O3 were measured at a high altitude station in the northwestern part of Turkey. The long‐ and short‐term trends in the concentrations of measured parameters were investigated to understand sources contributing to the observed concentrations of these pollutants. Higher concentrations of O3 during summer months were consistent with higher photochemical production with increased solar flux. Seasonal patterns observed in other parameter...
MEASUREMENTS OF SO2, NOX AND SPM IN AN INDUSTRIAL-AREA AT THE AEGEAN COAST OF TURKEY
ULU, Y; GULLU, GH; Tuncel, Süleyman Gürdal; KOSE, C; YAZAR, M; TUNCEL, G (1994-12-01)
Data from continuous measurements of SO2 NOx, suspended particulate matter (SPM) and meteorological parameters at seven sites around a highly industrialized region in the Aegean coast of Turkey, between July 15, 1991 to July 31, 1992 were used to evaluate spatial and temporal variations of air quality parameters. Low annual averages and insignificant differences between day and night concentrations were observed at stations far from sources. At stations close to sources, annual average concentrations were h...

Measurement of gas phase pollutants and aerosols at a mountainous site
Tuncel, Süleyman Gürdal; Ozer, U (1998-09-30)
Gas phase pollutants (O-3, NOx and SO2) suspended particulate matter (SPM), and major ions in aerosols were measured for 12 month period at a mountainous site of northwestern Turkey which is suffering from severe forest decline. Gaseous pollutants, SPM and meteorological parameters were measured in hourly basis with automated analyzers. Aerosol samples were collected daily. The long and short term trends in the concentrations of the measured parameters were investigated in order to understand the causes of ...
Measurement of the sum of WW and WZ production with W plus dijet events in pp collisions at root s=7 TeV
Chatrchyan, S.; et. al. (Springer Science and Business Media LLC, 2013-02-01)
A measurement of the inclusive WW+WZ diboson production cross section in proton-proton collisions is reported, based on events containing a leptonically decaying W boson and exactly two jets. The data sample, collected at root s = 7 TeV with the CMS detector at the LHC, corresponds to an integrated luminosity of 5.0 fb(-1). The measured value of the sum of the inclusive WW and WZ cross sections is sigma(pp -> WW + WZ) = 68.9 +/- 8.7 (stat.) +/- 9.7 (syst.) +/- 1.5 (lum.) pb, consistent with the standard mod...
