The main aim of this work is to evaluate the development of rainfall-runoff regime in selected river basins of the Šumava Mountains (Bohemian Forest), the Jeseníky Mountains and the Krušné Mountains (Ore Mountains) in the last 50 years. Besides the identification of inhomogeneity in time series of mean discharges, rainfall amounts, temperature and snow cover data, the work deals with an analysis of trends using annual and monthly data. Different methodological tools for identification of changes and trends in hydro-climatic time series have been introduced in this study, especially different methods of statistic testing and an application of Mann-Kendall seasonal test. The results have been compared not only from the point of view of the methods applied here, but as well from the viewpoint of geographical difference of the mentioned areas.

The article presents assessment and campaign results of the year 2014/2015. Weather during 2014 could be viewed as ideal during the whole vegetation period in Bohemia and as less favorable in Moravia, which resulted in significantly lower sugar content. These differences could be seen already during the pre-vegetative period when the precipitations were 235% and 46% of long-term average; by the end of autumn, the precipitation rate changed (30% and 310%). The end of the year was characterized as warm, deviation of average annual air temperature from the long-term average was +0.8 °C. Sugar beet processing in Czech sugar factories was the longest since 1918 and took 178.5 days (from 8 September 2014 to 3 March 2015). Average output was 111%, which represents daily processing capacity in individual factories from 2,133 t d–1 to 20,398 t d–1 of sugar beet. Average sugar content was 15.98% (it was within 15.14–17.40%). The amount of produced sugar was 595,440 t in white sugar value. Total of 4.2 mil. t of sugar beet and 314 thousand t of sugar beet for bio-sugar was processed. The main investment projects before the campaign aimed at boosting storage capacities for sugar (three silos for total 90 thousand t) and molasses (35 thousand m3) and at improvement of operation and the environment (pulpress, central dust collector, WWTP for sugar factory and distillery, candle filter and new carbonator with Richter pipes as well as actualization of the software and process controlling of several technological stations). Failure of the Krupp India centrifuge can be considered a blessing in disguise. © 2015, Listy Cukrovarnicke a Reparske. All rights reserved.

The author deals with superposition of cumulative frequency curves of flows in junctions in this paper. This is used more common distribution than the LN3 distribution. Than the superposition problem must be solved numerically because of impossibility to obtain the density function. Such estimates are the basic backgrounds for nearly all of hydrological reports produced by Czech Hydrometeorological Institute.

MACC (Monitoring Atmospheric Composition and Climate) is designed to meet the requirements that have been expressed for the pilot Core GMES Atmospheric Service. The project has been prepared by the consortia of the FP6 project GEMS and the GSE project PROMOTE, whose core service lines will provide the starting point for MACC. From mid-2009 MACC will continue, improve, extend, integrate and validate these service lines, so that the overall MACC system is ready near the end of 2011 for qualification as the operational GMES Atmospheric Core Service. MACC will prepare the core service in terms of implementation, sustained operation and availability. It will maintain and further develop the efficiency and resilience of the end-to-end pre-operational system, and will refine the scientific basis and quality of the products of the system. It will ensure that its service lines best meet both the requirements of downstream-service providers and end users at the European, national and local levels, and the requirements of the global scientific user community. The service lines will cover air quality, climate forcing, stratospheric ozone and solar radiation. MACC will deliver operational products and information that support the establishment and implementation of European policy and wider international programmes. It will acquire and assimilate observational data to provide sustained real-time and retrospective global monitoring of greenhouse gases, aerosols and reactive gases such as tropospheric ozone and nitrogen dioxide. It will provide daily global forecasts of atmospheric composition, detailed air-quality forecasts and assessments for Europe, and key information on long range transport of atmospheric pollutants. It will provide comprehensive web-based graphical products and gridded data on which downstream services may be based. Feedback will be given to space agencies and providers of in-situ data on the quality of their data and on future observational requirements.

Climate change is for a large part governed by atmospheric processes, in particular the interaction between radiation and atmospheric components (e.g. aerosols, clouds, greenhouse and trace gases). Some of these components are also those with adverse health effects influencing air quality. Strengthening the ground-based component of the Earth Observing System for these key atmospheric variables has unambiguously been asserted in the IPCC Fourth Assessment Report and Thematic Strategy on air pollution of the EU. However, a coordinated research infrastructure for these observations is presently lacking. ACTRIS (Aerosols, Clouds and Trace gases Research InfraStructure Network) aims to fill this observational gap through the coordination of European ground-based network of stations equipped with advanced atmospheric probing instrumentation for aerosols, clouds and short-lived trace gases. ACTRIS is a coordinated network that contributes to: providing long-term observational data relevant to climate and air quality research produced with standardized or comparable procedures; supporting transnational access to large infrastructures strengthening collaboration in and outside the EU and access to high quality information and services to the user communities; developing new integration tools to fully exploit the use of atmospheric techniques at ground-based stations, in particular for the calibration/validation/integration of satellite sensors and for the improvement of global and regional-scale climate and air quality models. ACTRIS supports training of new users in particular young scientists in the field of atmospheric observations and promotes the development of new technologies for atmospheric observation of aerosols, clouds and trace gases through close partnership with SMEs. ACTRIS will have the essential role to support integrated research actions in Europe for building the scientific knowledge required to support policy issues on air quality and climate change.
