Okosysteme setzen sich aus belebten (biotischen) und unbelebten (abiotischen) Komponenten zusammen, die uber Okosystemprozesse miteinander verbunden sind. Hier stehen also Organismen (Pflanzen, Tiere, Mikroorganismen) in Wechselbeziehung mit ihrer Umwelt. Die Wechselbeziehungen zwischen den verschiedenen Komponenten konnen sich gegenseitig positiv oder negativ beeinflussen (Smith und Smith 2009).

While capabilities in urban climate modeling have substantially increased in recent decades, the interdependency of changes in environmental surface properties and human (dis)comfort have only recently received attention. The open-source solar long-wave environmental irradiance geometry (SOLWEIG) model is one of the state-of-the-art models frequently used for urban (micro-)climatic studies. Here, we present updated calculation schemes for SOLWEIG allowing the improved prediction of surface tempe...

Abstract We investigate terrain effects on short-wave radiation measurements at Kanzelhohe Observatory (KSO), a mountainous radiation monitoring site in the Austrian Southern Alps, using three-dimensional (3-D) radiative transfer (RT) modeling and observations. The magnitude of terrain effects on global radiation is experimentally assessed through the comparison of 10-min measurement segments ex−/including terrain reflected radiation. The reflected component is ex−/included in global solar irrad...

Abstract While compliance with air quality standards is evaluated at individual monitoring stations, projections of future ambient air quality for global climate and emission scenarios often rely on coarse resolution models. We describe a statistical transfer approach that bridges the spatial gap between air quality projections, averaged over four broad U.S. regions, from a global chemistry-climate model and the local level (at specific U.S. CASTNet sites). Our site-level projections are intende...

This study investigates the influence of low ozone episodes on UV-B radiation in Austria during the period 1999 to 2015. To this aim observations of total column ozone (TCO) in the Greater Alpine Region (Arosa, Switzerland; Hohenpeissenberg, Germany; Hradec Kralove, Czech Republic; Sonnblick, Austria), and erythemal UV-B radiation, available from 12 sites of the Austrian UV-B monitoring network, are analyzed. As previous definitions for low ozone episodes are not particularly suited to investiga...

In recent decades, automated sensors for sunshine duration (SD) measurements have been introduced in meteorological networks, thereby replacing traditional instruments, most prominently the Campbell-Stokes (CS) sunshine recorder. Parallel records of automated and traditional SD recording systems are rare. Nevertheless, such records are important to understand the differences/similarities in SD totals obtained with different instruments and how changes in monitoring device type affect the homogen...

The goal of the Tropospheric Ozone Assessment Report (TOAR) is to provide the research community with an up-to-date scientific assessment of tropospheric ozone, from the surface to the tropopause. While a suite of observations provides significant information on the spatial and temporal distribution of tropospheric ozone, observational gaps make it necessary to use global atmospheric chemistry models to synthesize our understanding of the processes and variables that control tropospheric ozone a...

Vertikalni profily ozonu ziskane metodou Umkehr pomoci Brewerova spektrofotometru B199 v obdobi 2010-2016 byla porovnana s měřenimi ECC ozonových sond. Na zakladě tohoto porovnani byl vytvořen nový set a-priori profilů pro podminky poskozene ozonove vrstvy.

Winter storms pose numerous hazards to the Northeast United States, including rain, snow, strong wind, and flooding. These hazards can cause millions of dollars in damages from one storm alone. This study investigates meteorological intensity and impacts of winter storms from 2001 to 2014 on coastal counties in Connecticut, New Jersey, and New York and underscores the consequences of winter storms. The study selected 70 winter storms on the basis of station observations of surface wind strength,...
