Nitrogen Oxides in the North Atlantic Troposphere: Impacts of Boreal Wildfire and Anthropogenic Emissions

Nitrogen oxides play a crucial role in the budget of tropospheric ozone (O sub(3)) and the formation of the hydroxyl radical. Anthropogenic activities and boreal wildfires are large sources of emissions in the atmosphere. However, the influence of the transport of these emissions on nitrogen oxides and O sub(3) levels at hemispheric scales is not well understood, in particular due to a lack of nitrogen oxides measurements in remote regions. In order to address these deficiencies, measurements of NO, NO sub(2) and NO sub(y) (total reactive nitrogen oxides) were made in the lower free troposphere (FT) over the central North Atlantic region (Pico Mountain station, 38 degree N 28 degree W, 2.3 km asl) from July 2002 to August 2005. These measurements reveal a well-defined seasonal cycle of nitrogen oxides (NO sub(x) = NO+NO sub(2) and NO sub(y)) in the background central North Atlantic lower FT, with higher mixing ratios during the summertime. Observed NO sub(x) and NO sub(y) levels are consistent with long-range transport of emissions, but with significant removal en-route to the measurement site. Reactive nitrogen largely exists in the form of PAN and HNO sub(3) ( similar to 80-90% of NO sub(y)) all year round. A shift in the composition of NO sub(y) from dominance of PAN to dominance of HNO sub(3) occurs from winter-spring to summer-fall, as a result of changes in temperature and photochemistry over the region. Analysis of the long-range transport of boreal wildfire emissions on nitrogen oxides provides evidence of the very large-scale impacts of boreal wildfires on the tropospheric NO sub(x) and O sub(3) budgets. Boreal wildfire emissions are responsible for significant shifts in the nitrogen oxides distributions toward higher levels during the summer, with medians of NO sub(y) (117-175 pptv) and NO sub(x) (9-30 pptv) greater in the presence of boreal wildfire emissions. Extreme levels of NO sub(x) (up to 150 pptv) and NO sub(y) (up to 1100 pptv) observed in boreal wildfire plumes suggest that decomposition of PAN to NO sub(x) is a significant source of NO sub(x), and imply that O sub(3) formation occurs during transport. Ozone levels are also significantly enhanced in boreal wildfire plumes. However, a complex behavior of O sub(3) is observed in the plumes, which varies from significant to lower O sub(3) production to O sub(3) destruction. Long-range transport of anthropogenic emissions from North America also has a significant influence on the regional NO sub(x) and O sub(3) budgets. Transport of pollution from North America causes significant enhancements on nitrogen oxides year-round. Enhancements of CO, NO sub(y) and NO sub(x) indicate that, consistent with previous studies, more than 95% of the NO sub(x) emitted over the U.S. is removed before and during export out of the U.S. boundary layer. However, about 30% of the NO sub(x) emissions exported out of the U.S. boundary layer remain in the airmasses. Since the lifetime of NO sub(x) is shorter than the transport timescale, PAN decomposition and potentially photolysis of HNO sub(3) provide a supply of NO sub(x) over the central North Atlantic lower FT. Observed Delta O sub(3)/ Delta NO sub(y) and large NO sub(y) levels remaining in the North American plumes suggest potential O sub(3) formation well downwind from North America. Finally, a comparison of the nitrogen oxides measurements with results from the global chemical transport (GCT) model GEOS-Chem identifies differences between the observations and the model. GEOS-Chem reproduces the seasonal variation of nitrogen oxides over the central North Atlantic lower FT, but does not capture the magnitude of the cycles. Improvements in our understanding of nitrogen oxides chemistry in the remote FT and emission sources are necessary for the current GCT models to adequately estimate the impacts of emissions on tropospheric NO sub(x) and the resulting impacts on the O sub(3) budget.

Contribution of Starlette, Stella, and AJISAI to the SLR-derived global reference frame

The contribution of Starlette, Stella, and AJI-SAI is currently neglected when defining the International Terrestrial Reference Frame, despite a long time series of precise SLR observations and a huge amount of available data. The inferior accuracy of the orbits of low orbiting geodetic satellites is the main reason for this neglect. The Analysis Centers of the International Laser Ranging Service (ILRS ACs) do, however, consider including low orbiting geodetic satellites for deriving the standard ILRS products based on LAGEOS and Etalon satellites, instead of the sparsely observed, and thus, virtually negligible Etalons. We process ten years of SLR observations to Starlette, Stella, AJISAI, and LAGEOS and we assess the impact of these Low Earth Orbiting (LEO) SLR satellites on the SLR-derived parameters. We study different orbit parameterizations, in particular different arc lengths and the impact of pseudo-stochastic pulses and dynamical orbit parameters on the quality of the solutions. We found that the repeatability of the East and North components of station coordinates, the quality of polar coordinates, and the scale estimates of the reference are improved when combining LAGEOS with low orbiting SLR satellites. In the multi-SLR solutions, the scale and the Z component of geocenter coordinates are less affected by deficiencies in solar radiation pressure modeling than in the LAGEOS-1/2 solutions, due to substantially reduced correlations between the Z geocenter coordinate and empirical orbit parameters. Eventually, we found that the standard values of Center-of-mass corrections (CoM) for geodetic LEO satellites are not valid for the currently operating SLR systems. The variations of station-dependent differential range biases reach 52 and 25 mm for AJISAI and Starlette/Stella, respectively, which is why estimating station dependent range biases or using station-dependent CoM, instead of one value for all SLR stations, is strongly recommended.This clearly indicates that the ILRS effort to produce CoM corrections for each satellite, which are site-specific and depend on the system characteristics at the time of tracking,is very important and needs to be implemented in the SLR data analysis.

The Role of Chinese Plants in Hungarian Landscape Architecture

Most outdoor plants in Hungarian horticulture are exotas mainly from Middle and East Asia and North America. The flora of China is diversified and has many species because the last glacial period did not reach China. The richness of the Chinese flora was known for Europeans by the missionaries and medics first in 19th cectury. Later some bigger nurseries sent expeditions in China to collect new plants. Nowadays the Hungarian landscape architecture is impossible without Chinese plants.

Comunicazione urbana nelle città storiche del Sol Levante: l'esperienza di Kyoto tra tradizione e innovazione

The book collects the Papers (from Europe, Asia and Latin America) presented at the Workshop organized by the ICOMOS International Committee in Historic Towns and Villages (CIVVIH) and by ICOMOS Italy in Palazzo Coppini (branch of Fondazione Romualdo del Bianco) in Florence (March 3-4, 2016) and focus on the comparison of different propositions of digital urban signage to realize a good quality of the “visit experience” in the historical towns, not only as urban marketing, but of a authenticity genuine culture. The urban culture founded on the identity and authenticity of every historical towns and their multilayered history must be the objective of an tourism of culture for the inhabitants and the visitors. The book focused its interest on the outstanding existing urban assets in Europe, Asia and Latin America, and heritage not sufficiently promoted.

The last dicynodont: An Australian Cretaceous relict

Some long-forgotten fossil evidence reveals that a dicynodont (mammal-like reptile of the infraorder Dicynodontia) inhabited Australia as recently as the Early Cretaceous, ca. 110 Myr after the supposed extinction of dicynodonts in the Late Triassic. This remarkably late occurrence more than doubles the known duration of dicynodont history (from ca. 63 Myr to ca. 170 Myr) and betrays the profound impact of geographical isolation on Australian terrestrial faunas through the Mesozoic. Australia's late-surviving dicynodont may be envisaged as a counterpart of the ceratopians (homed dinosaurs) in Cretaceous tetrapod faunas of Asia and North America.

Bâtir des territoires cultuels pour construire des identités

Le théologien protestant Olivier Bauer réfléchit sur la manière dont les actions liturgiques bâtissent des espaces cultuels et sur les identités qu’elles construisent ainsi. Ses réflexions sont nourries par son expérience des cultes sur 3 continents, en Europe, en Océanie et en Amérique du Nord. Dans une première partie, il détaille ce que font les officiants et les célébrants – célébrer, regarder, bouger, écouter, s’exprimer, toucher, manger, sentir… – pour faire apparaître les représentations de l’espace cultuel qu’elles créent. Dans une seconde partie, il met en évidence les conséquences de l’aménagement d’un territoire cultuel sur l’identité religieuse de celles et ceux qui le fréquentent : sur leurs relations à Dieu, à l’Église et au culte lui-même.

Mutual perceptions of Asia and the EU/Europe. Media, elite and public opinion in Singapore and Germany. EU Centre in Singapore Working Paper No. 12, December 2012

In an increasingly interlinked and interdependent world, Europe and Asia are key players. Free trade agreements (FTAs), such as the ones the EU concluded with South Korea and Singapore, are indicative of strong mutual economic interests. It is therefore timely to take a closer look at the mutual perceptions of Asians and Europeans – not only at the governmental and policymaking levels, but also in terms of public opinion and the media. Drawing on data from an extensive research project led by the National Centre for Research on Europe (NCRE), New Zealand, the empirical study in this paper assesses the mutual perceptions of the EU/Europe and Asia, and their respective actors, focusing on two countries – Germany and Singapore. It seeks to do so through an analysis of the data collected from print and broadcast media, interviews with media practitioners, and the findings from public opinion surveys.

OSW Raport, wrzesien 2010. = German networks in the east. German soft power in Eastern Europe, Central Asia and South Caucasus policy - administration - culture - science - the society of. CES Report, September 2010

Do realizacji niemieckich interesów w polityce zagranicznej, bezpieczeństwa i gospodarczej RFN wykorzystuje instrumenty soft power z obszaru dyplomacji publicznej, polityki rozwojowej, kulturalnej i naukowej. Budowanie sieci kontaktów i lobbing polityczny, programy współpracy rozwojowej oraz zagranicznej polityki kulturalnej i naukowej, mają służyć wspieraniu niemieckiej gospodarki uzależnionej od eksportu, uzyskaniu statusu europejskiego ośrodka technologii i innowacji oraz zwiększeniu wpływu RFN na działania zewnętrzne UE. Jednym z priorytetowych obszarów stosowania tych instrumentów są dla Niemiec państwa Europy Wschodniej, Kaukazu Południowego i Azji Centralnej. Decydują o tym bliskość geograficzna i otwierające się rynki zbytu, konieczność modernizacji gospodarek tych krajów, zagrożenia dla „miękkiego” bezpieczeństwa RFN oraz rozwój relacji UE z tymi państwami. Niemiecka aktywność jest w tych krajach niezależna od sytuacji politycznej i stanowi długofalową strategię ugruntowującą pozycję RFN jako ich najważniejszego europejskiego partnera gospodarczego i politycznego.
