  • Contrasting suspended covers reveal the impact of an artificial monolayer on heat transfer processes at the interfacial boundary layer

    The highly variable performance of artificial monolayers in reducing evaporation from water storages has been attributed to wind speed and wave turbulence. Other factors operating at the interfacial boundary layer have seldom been considered. In this paper, two physical shade covers differing in porosity and reflectivity were suspended over 10 m diameter water tanks to attenuate wind and wave ...

  • Monitoring mixing dynamics in Toolik Lake, Alaska

    Toolik Lake is 130 miles south of Prudhoe Bay in northern Alaska. It is one of the main monitoring sites of the Arctic Long-Term Ecological Research (LTER) project and a site for studies led by Sally MacIntyre of the University of California investigating the linkages between hydrodynamics and ecosystem function. Both studies are funded by the U.S. National Science Foundation. It is classified as ...

  • A simple methodology for surface layer characterization during diabatic extremes

    Increased global environmental awareness has fostered widespread use of remote automated weather station (RAWS) networks to monitor meteorological conditions, and reliance on atmospheric dispersion modeling for decisions concerning pollutant dispersion. Dispersion models require as input a characterization of surface layer (SL) heat and momentum fluxes and turbulence. Characterization of these ...

  • Gill Instruments case study featured in AWE International

    AWE International magazine, which is focused on the environmental analysis industry, recently featured Gill Instruments in a case study about environmental monitoring with solid-state meteorological instruments. The case study includes information about all of the products within the Gill Instruments range, with information about their advantages within the environmental analysis field. We have ...

  • Using the HydraProbe Soil Sensor for Determination of Flood Risk in the New York State Mesonet

    New York's Mesonet uses the HydraProbe and other meteorological sensors to help forecast flood hazards and climate. In January 2014, the Department of Homeland Security established the New York State Early Warning Weather Detection System. The centerpiece of the system is the New York State Mesonet, a network of 125 weather stations across the state, with at ...

  • Why Does the Non-Orthogonal Sonic Anemometer Underestimate

    The performance of non-orthogonal sonic anemometers has been the subject of much discussion in recent years.  It followed findings that they underestimated vertical winds and vertical heat fluxes by 10-15%.  For agricultural and forestry scientists who depended on them for their large-scale energy balance studies this was a bad surprise.  They had collected turbulence data from ...

  • EPA Technology News & Trends - Tacoma “Well 12A” Superfund Site

    The U.S. EPA Region 10 office uses an adaptive site management approach that relies on high-resolution site characterization (HRSC) techniques for strategic sampling at the Well 12A project area. This approximate one-square-mile project area is one of three at the 2.5-square-mile Commencement Bay-South Tacoma Channel Superfund site in Tacoma, Washington. The vicinity of Well 12A, one of 13 wells ...

  • To MACT and Beyond case study

    In the 1970s, FMC Corp., a chemical manufacturer headquartered in Philadelphia, began operating a high-efficiency thermal destruction facility to dispose of hazardous liquid wastes at its Baltimore pesticide manufacturing plant. The facility used a thermal oxidizer with a rapid quencher and packed tower scrubber to remove air pollution emissions. The system was upgraded in the early ’80s ...

  • Reducing Odor and VOC Emissions

    The Montgomery County Regional Composting Facility (MCRCF) in Silver Spring, Maryland is designed to process 400 wet tons/day of lime amended biosolids from the Blue Plains Wastewater Treatment Plant (WWTP) in Washington, D.C. Recently, political pressures forced operations to cease at the MCRCF. Although the aerated static pile composting plant’s fate has not been completely decided, its owner, ...

  • Variable frequency drive energy saving on air compressors

    When we are looking for an innovative way to make its rotary-screw compressors more energy efficient and operator-friendly, they turned to Gozuk, Low-Voltage VFDs. In addition to supplying VFDs to control the speed and torque of the AF-series compressors, the Gozuk project team designed software to control the system pressure, air delivery, oil temperature and duty cycle directly from the VFD. ...

  • EMEP/EEA air pollutant emission inventory guidebook 2016

    1 Guidebook Introduction 1.1 Introduction The joint EMEP (1)/EEA Air Pollutant Emission Inventory Guidebook (the 'Guidebook'), following the 'Guidelines for Reporting Emissions and Projections Data' under the United Nations Economic Commission for Europe (UNECE) Convention on Long-range Transboundary Air Pollution (LRTAP) (2), provides concise guidance on how ...

  • Application of Membrane Technology for the Recovery and Reuse of Water

    Abstract As water and sewer costs are expected to increase over the next decade, membrane technology will continue to be a viable and economical option in the recovery and reuse of water. This paper describes the mechanism of membrane effected separation (specifically reverse osmosis, ultrafiltration and microfiltration), membranes commercially available, membrane element configurations, and how ...


  • Consideration of the Effects of Remediation Technologies on Natural Attenuation.

    ABSTRACT: We have long understood and continue to improve our understanding of the geochemical conditions that favor biodegradation of petroleum hydrocarbons. Over the last several years our understanding of the conditions that are necessary for and/or promote reductive dechlorination of chlorinated hydrocarbons has improved substantially. Over this time in situ remediation technologies have ...
