  • Understanding the impact of snow`s reflectance

    To help improve the accuracy of climate models, an international team involving the National Physical Laboratory (NPL) has measured the reflectance of rough, snow-covered surfaces at large solar zenith angles. A crucial factor in climate models is Earth's albedo, which is the reflectance of Earth's surface: dark ground has a low albedo, reflecting little light, whereas ice and snow have a high ...

  • Chloride transport and related processes at a municipal snow storage and disposal site

    The practice of used snow disposal has evolved from indiscriminate snow dumping to storage and meltwater management at engineered snow disposal sites. The Town of Richmond Hill, Ontario, Canada, constructed such a snow disposal site in 2003. Environment Canada and the Town of Richmond Hill formed a partnership to investigate the operation of the Richmond Hill Snow Storage Facility (RHSSF) with ...

  • Catchment-scale evaluation of pollution potential of urban snow at two residential catchments in southern Finland

    Despite the crucial role of snow in the hydrological cycle in cold climate conditions, monitoring studies of urban snow quality often lack discussions about the relevance of snow in the catchment-scale runoff management. In this study, measurements of snow quality were conducted at two residential catchments in Espoo, Finland, simultaneously with continuous runoff measurements. The results of ...

  • Dust monitoring

    Generally, two different approaches are used to measure the amount of dust deposited on a surface; Determination of the soiling of a surface, by a change in its properties; Determination of the quantity of dust deposited, by weight. WHAT IS DUST? Dust is a generic term used to describe fine particles that are suspended in the atmosphere. Dust comes from a wide variety of sources, including soil, ...

  • What You Don’t Know About Snow: The USDA’s SNOTEL Network is Playing a Critical Role in Protecting Water Resources in the Western United States

    There are many complex political, social, environmental, and scientific challenges surrounding water resources in the western United States. Water is scarce and does not occur when and where people need it the most. According to the US Geological Survey (USGS), about 80 percent of fresh water used in the western United States is appropriated for irrigation. Over the past 150 years, society has ...

  • Climate monitoring - meeting the challenge

    Average global temperatures are on the increase, ice and snow cover is disappearing fast and sea levels are rising. In addition, severe weather situations are becoming more frequent and more extreme. There is clear evidence that the Earth’s atmosphere and oceans are warming: 11 of the 12 years in the period 1995-2006 were among the 12 warmest since 1850. Climate change is a reality and it is ...

  • Tekran instruments—monitoring around the world

    Tekran provides trace-level mercury analytical and monitoring technology for a variety of applications including laboratory-based sample analysis, continuous point-source emissions and ambient air monitoring. This article focuses on and highlights the results of an application of Tekran’s Ambient Air Mercury Speciation System. In contrast to most other heavy metals, mercury (Hg) and mercury ...

  • Reduction of Train Noise Monitored by New Measurement Station

    With increasing passenger and freight traffic, the strengthening of the rail traffic is an important and actual issue. For sustainable mobility, the reduction of noise pollution caused by trains is essential. All involved parties agree on one claim: Increase railway traffic, decrease railway noise! Additional to two already existing stations measuring road traffic noises, ...

  • Groundwater monitoring and assessment with ESdat environmental data management software and its use in groundwater remediation plans

    Groundwater investigations, contaminated/industrial sites, landfill and regulatory compliance are all ideal areas for environmental consultants and site managers, specializing in groundwater monitoring and assessment, to use environmental data management software. A successful groundwater ...

  • A tool and methodology for designing the optimisation activities of a logistic system – case study

    The current economic crisis combined with increasing fuel costs raises awareness that in value chains the logistics represents a large portion of costs and hence modern companies are increasingly interested in investments in research and development of specialised fleet optimisation tools. A new tool and methodology that enable the end-user to carry out a logistic research and optimisation in a ...

  • Improved Water Supply Forecasts Using Soil Moisture Data

    HydraProbe used to improve water supply forecast from 3 SNOTEL sites in Idaho over traditional antecedent conditions using the principle component forecast model Much of the water in the Western United States used for irrigation, municipal supplies and hydro-electric production originates as winter snow pack at higher elevations. Since the early 1900s, the correlation between stream flow and the ...

  • Impact of recycled water use at mammoth golf courses on basin groundwater quality

    ABSTRACT The Mammoth Community Water District’s proposed plan for recycled water use in golf course irrigation as a solution to the district’s water shortage problem develops concerns over protecting its basin groundwater quality. A detailed assessment through model development, and monitoring and testing is done in this study to determine the fate and transport of concerned pollutants in ...

  • Application of IHACRES rainfall-runoff model to the Wadi Dhuliel arid catchment, Jordan

    With increasing stress on water resources in Jordan, application of rainfall-runoff models can be part of the solution to manage and sustain the water sector. In this paper, the metric conceptual IHACRES model is applied to the Wadi Dhuliel arid catchment, north-east Jordan. Rainfall-runoff data from 19 storm events during 1986 to 1992 have been used in this study. Flood estimation was performed ...

  • Triad expedites brownfields redevelopment in Fairbanks

    The Fairbanks North Star Borough (FNSB) used Triad in 2006-2007 to assess environmental conditions at a municipal property along the Chena River in Fairbanks, AK. FNSB accelerated the site investigation as part of a brownfields assessment grant received from the U.S. EPA in 2005. Low-level contamination had been identified onsite in past investigations, but its extent and impact on future ...

  • 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.

  • Bedbug Problem? Carbon Dioxide (CO2) Solution.

    Bedbug infestation is an extremely common problem worldwide. Bedbugs are small, nocturnal parasites that feed off of warm blooded animals and humans. They can survive in a wide range of temperature, low humidity and live for a year without eating. Adults can measure up to 5 mm in length and up to 3 mm wide. They are attracted to carbon dioxide (CO2) levels in human respiration and body warmth. ...
