  • Statistical analysis and inter-comparison of the solar UVB, UVA and global radiation for Beer Sheva and Neve Zohar (Dead Sea), Israel

    A statistical analysis and inter-comparison of the solar UVB, UVA and global radiation for Beer Sheva and Neve Zohar (Dead Sea) are presented utilizing data measured from January 1995 through December 2002. Beer Sheva is located approximately 65km to the west of and 700m above Neve Zohar. The monthly average hourly and daily values for all radiation types at both sites are reported. The standard ...

  • Relating geo–meteorological parameters to global solar radiation for Egypt by Iranna–Bapat's estimation models

    Estimation of solar radiation is considered as the most important parameter for the design and development of various solar energy systems. But, the availability of the required data is very scarce and often not readily accessible. The foremost objective of the present study was to estimate the monthly average global solar radiation (GSR) at various locations for Egypt, by the generalised ...

  • Non-Ionising Radiation

    Pressures on the environment may occur through chemical, physical and biological agents. The subject of this study is physical agents, where physical fields are examined. Physical fields are part of the natural environment. Depending upon their properties and the surrounding conditions, physical fields are transmitted through the spaces in which we live, potentially affecting human health and ...

  • Relationships between photosynthetically active radiation and clearness index at Bloemfontein, South Africa

    Relationships between photosynthetically active radiation (PAR) and solar radiation (SR) and between diffuse radiation and global radiation at Bloemfontein, South Africa were investigated. The ratio of PAR to SR (PAR/SR) has been reported from many places in the northern hemisphere, but there were not many PAR/SR measurements documented from the southern hemisphere, including the study region. ...

  • Global aerosols studied by NILU

    Aerosols scatter and absorb solar radiation and thereby influence the radiation in the atmosphere and the global climate. To understand the climate system and the ongoing climate change it is important to know the distribution of aerosols in the atmosphere. Satellites provide an extremely useful tool to study this distribution, especially since it is very inhomogeneous with respect to ...

  • Helplessly exposed to nature? How lightning storms can be measured

    Each day, there occur about 1,000 thunderstorms with 4-10 million lightning bolts worldwide. In average, 700 people per year are hit by such light discharges, of which 75% of the hits result in long-term damages. Between three and seven cases end fatal. The risk is particularly high in the open field and is fortunately decreasing. The reason for this is that we stay more often inside in cars and ...

  • Weather measurement during FIFA Confederations Cup 2013 / FIFA World Cup 2014 - Brazil - Case Study

    The compact weather station WS301-UMB is part of a mobile station for measurement and monitoring of climate measurements during the FIFA Confederations Cup 2013 and the FIFA World Cup 2014 in Brazil. All soccer stadiums that took part on the FIFA Confederations Cup were already equipped with this stations. The weather stations measure temperature, rel. humidity, air pressure and global ...

  • Ecological design for climate mitigation in contemporary urban living

    Evaporation is the most important hydrological function on Earth because it provides rain. As deforestation and urbanisation reduce plant cover and evapotranspiration, ever more short-wave solar radiation is converted to long-wave thermal emissions and sensible heat. Higher surface temperatures set up heat island effects, contributing to local, and ultimately, global climate change. Rainwater ...

  • Case study - Buoy-based temperature profiling in the Bavarian Lakes

    In summertime a temperature stratification occurs in deep lakes – the surface water is warm, but deep down the water is cold.  This has considerable influence on the nutrient balance and the biological habitat in these lakes. Due to generally higher air temperatures induced by the climate change, both change and have effects on the life conditions of the ecosystems in the lakes. ...

  • Great Lakes need great Data Buoys

    One recently finished project was performed by the University of Wisconsin and has comprised the depolyment of two data buoys which are both furnished with a multifunctional Lufft WS501-UMB. These weather ...

  • Status of black carbon monitoring in ambient air in Europe

    Black carbon (BC) is increasingly discussed in science and environmental policy areas as an example of an air pollutant that affects both human health and contributes to climate change (e.g. WHO, 2012; UNEP/WMO, 2011; Bond et al., 2013; IPCC, 2013). In order to be able to make comparable measurements of BC in ambient air and to relate BC monitoring to health impacts and climate change it is ...

  • DNI satellite data truth? - How to handle the difference in values derived from different satellite data providers?

    Technical Top Tip courtesy of Solar Resource Assessment - When it comes to CSP project evaluation, one of the biggest uncertainty factors for the performance is the available Direct Normal Irradiance (DNI) at the site. 1. DNI vs. GHI DNI distinguishes significantly from GHI (Global Horizontal Irradiance), which is more applicable for Photovoltaic ...

  • Q&A: Patrick Wagnon on glaciers and climate change

    Patrick Wagnon is a glaciologist at the Institute of Research for Development in France, and a visiting scientist at the International Centre for Integrated Mountain Development in Kathmandu, Nepal. As a global ‘glacier chaser’, he has summited some of the highest mountains in the world, including the 8,516 metre Lhotse in the Himalayas. In 2001, Wagnon and his fellow glaciologist ...

  • Change is the only constant

    2016 was a year of big changes for Lufft: A change in the ownership structure took place in January and in August I took the reins as the new Managing Director. After more than 100 days at the innovative measuring technology manufacturer with a long company history, I would like to share with you my experiences and impressions in the new position. What characterizes Lufft? A good mix! ...

  • Impacts of Climate Change on the Occurrence of Harmful Algal Blooms

    Climate change has been occurring naturally as well as caused by anthropogenic activities over the decades. In relation to the fresh and marine water, the concentration of greenhouse gases results in temperature rise of surface water, lower pH and changes to precipitation, evaporation and vertical mixing of water. All these consequences of changing the environment in combination with excessive ...

  • New monitoring technology helps reveal Arctic secrets

    A group of Arctic researchers has employed the latest monitoring technology to investigate the effects of climate change, by measuring temperature and salinity in the water column beneath surface ice. The results of the investigation, which utilised YSI’s new 'Castaway-CTD', could cast new light on our understanding of the ways in which shifting ocean currents impact upon the climate in ...

  • Closures of mine a new challenge for Romania

    AbstractThe mining activity is one of the oldest activity in Romania, dating from the year 100 B.C. The gold and silver ores represented one of the riches of our country. In time the economic content of metals diminuend, and the ore mines become non profitable. Due to this situation the best option of the State was the closure and ecological rehabilitation of the mines.The steps for the ...
