A portable Fourier Transform Spectrometer (B3M-IR) is built and used to measure atmospheric trace gases in the city of Beijing during Olympic Games in 2008. A short description of the instrument is first provided in this paper. A detailed spectral analysis is then presented. The total columns of ozone (O3), carbon monoxide (CO), methane (CH4) and nitrous oxide (N2O) are retrieved from the ground-based solar absorption spectra recorded by the B3M-IR during the Olympic Games. Lacking validation data, only the retrieved total column of O3 is compared with that retrieved by MAX-DOAS, which is deployed at the same station. The mean difference between the two methods of measurement is 6.5%, demonstrating the performance and reliability of B3M-IR.

[222 pp, RRP: £18.75, ISBN: 978-1-910781-22-7]The idea of discovering or creating a form of uniqueness to differentiate a place from others is clearly attractive. In this regard, and in line with Ashworth (2009), three urban planning instruments are widely used throughout the world as a means of boosting a city’s image: (i) personality association - where places associate themselves with a named individual from history, literature, the arts, politics, entertainment, sport or even mythology; (ii) the visual qualities of buildings and urban design, which include flagship building, signature urban design and even signature districts and (iii) event hallmarking - where places organize events, usually cultural (e.g., European Capital of Culture, henceforth referred to as ECoC) or sporting (e.g., the Olympic Games), in order to obtain worldwide recognition.

Abstract. The collection 3 Ozone Monitoring Instrument (OMI) Total Column Water Vapor (TCWV) data generated by the Smithsonian Astrophysical Observatory's (SAO) algorithm version 1.0 and archived at the Aura Validation Data Center (AVDC) are compared with NCAR's ground-based GPS data, AERONET's sun-photometer data, and Remote Sensing System's (RSS) SSMIS data. Results show that the OMI data track the seasonal and interannual variability of TCWV for a wide range of climate regimes. During the period from 2005 to 2009, the mean OMI−GPS over land is −0.3 mm and the mean OMI−AERONET over land is 0 mm. For July 2005, the mean OMI−SSMIS over the ocean is −4.3 mm. The better agreement over land than over the ocean is corroborated by the smaller fitting residuals over land and suggests that liquid water is a key factor for the fitting quality over the ocean in the version 1.0 retrieval algorithm. We find that the influence of liquid water is reduced using a shorter optimized retrieval window of 427.7–465 nm. As a result, the TCWV retrieved with the new algorithm increases significantly over the ocean and only slightly over land. We have also made several updates to the air mass factor (AMF) calculation. The updated version 2.1 retrieval algorithm improves the land/ocean consistency and the overall quality of the OMI TCWV data set. The version 2.1 OMI data largely eliminate the low bias of the version 1.0 OMI data over the ocean and are 1.5 mm higher than RSS's “clear” sky SSMIS data in July 2005. Over the ocean, the mean of version 2.1 OMI−GlobVapour is 1 mm for July 2005 and 0 mm for January 2005. Over land, the version 2.1 OMI data are about 1 mm higher than GlobVapour when TCWV  <  15 mm and about 1 mm lower when TCWV  >  15 mm.

This paper deals with basic points which comprise Olympic and “sport“ education in the Greek antiquity. Until the emergence of professionalism in ancient athletics was the essence of "sport" education and Olympism the areas known as free “sport“, nudity, construction of “sports“ buildings, organizing of many games and relation of society to the Olympic winners as well as leading the citizens to cultural and philosophical ideals. The education itself to the Olympic Games and “sport“ had an important role in ancient Greece. Victory in the Panhellenic Games was very important not only for the victors as individuals, but also for their lineage and the city-state. Each victor entered the next level, which was close to the heroes and gods. They acquired semi-divine status and the homages for them by all society and mainly by the city-states were greatly important for cultural outputs and conception of all society. The influence of victors on youth was huge and this influence was one of the most important educational parts of all ancient Greek culture. The winners of great Panhellenic Games, especially the winners of the Olympic Games or περιοδονῑκοι (periodonikoi), were the best role models with big cultural power and the best examples for youth. Successes of ancient athletes supported sport education of young Greek boys, thus also the military training and this conception created better warriors and defenders of the city-states.

Conceptual approaches to development of the region during the post-Olympic period are presented in the article. Conclusions that after the end of the Olympic Games, the region of their carrying out faces the recessive period are drawn. At the same time, tasks of finding new growth points and development of strategy of further development of the region based on improvement under the new conditions of the General plan come out on top in such conditions. The main directions of further social and economic development of the Sochi resort agglomeration are considered. It is shown that further development of economy and infrastructure of Sochi and creation of conditions for its accelerated development during the post-Olympic period are possible only on the basis of the strategized General plan of the city.

Abstract. In this investigation we analyze two common optical configurations to retrieve CO2 total column amounts from solar absorption infrared spectra. The noise errors using either a KBr or a CaF2 beam splitter, a main component of a Fourier transform infrared spectrometer (FTIR), are quantified in order to assess the relative precisions of the measurements. The configuration using a CaF2 beam splitter, as deployed by the instruments which contribute to the Total Carbon Column Observing Network (TCCON), shows a slightly better precision. However, we show that the precisions in XCO2 ( =  0.2095  ⋅  Total Column CO2Total Column O2) retrieved from  >  96 % of the spectra measured with a KBr beam splitter fall well below 0.2 %. A bias in XCO2 (KBr − CaF2) of +0.56 ± 0.25 ppm was found when using an independent data set as reference. This value, which corresponds to +0.14 ± 0.064 %, is slightly larger than the mean precisions obtained. A 3-year XCO2 time series from FTIR measurements at the high-altitude site of Altzomoni in central Mexico presents clear annual and diurnal cycles, and a trend of +2.2 ppm yr−1 could be determined.

The Olympic Games

Every four years the Summer Olympic Games fires the imagination of the largest and most diverse sport spectatorship and entices them in their hundreds of thousands to some of the First World’s most iconic and crowded cities. In addition, the ideological symbolism associated with the Olympic Games is rooted in Western, liberal democratic values and traditions. For those who do not share these ideals the Olympics represent something to stand against and, in extremity, disrupt and violate. In short, in a post-9/11 world, the Olympics provide a mouth-watering target for terrorists. Using themes of surveillance drawn form from Bentham and Foucault, this article analyses the nature of the terrorist threat and scale of the security operation designed to ensure the safety of the London 2012 Olympic Games. It concludes by considering the consequences of these measures on the city of London, particularly in terms of the civil liberties of its citizenry.
