  • Micro Pulse LiDAR measures aerosols caused by biomass burning - Case Study

    From June to October, the burning of agricultural fields in southern Africa creates smoke that blows west across the southeastern Atlantic Ocean and reaches Brazil, over 4,500 miles away. Using Micro Pulse LiDAR (MPL) and other instruments, researchers at the Atmospheric Radiation Measurement (ARM) user facility on the remote island of Ascension, operated by the U.S. Department of Energy, ...

  • Micro Pulse LiDAR: A Critical Tool for Emissions Source Detection

    Micro Pulse LiDAR remote sensing data are used to calculate a highly accurate Planetary Boundary Layer (PBL) height to improve plume models that help assess emissions sources. ...

  • Multiple Instruments Work Together for a Better View of Air Quality

    Accurately identifying and quantifying particulate matter (PM) in the atmosphere is key to determining air quality. Researchers are particularly interested in PM that have a diameter of less than 2.5 micrometers because they are believed to contribute to heart and lung disease in humans and animals. These tiny particles are invisible to the naked eye and originate from power plants, fires, and ...

  • Top 5 Differences between Micro Pulse LiDAR and Ceilometer Technology

    If you are evaluating backscatter LiDAR sensors for measuring aerosols, cloud vertical structure, and planetary boundary layer (PBL) heights, what factors should you consider in your comparison? It really comes down to a choice between the traditional analog technology used in ceilometers and the more recent advanced technology found in Micro Pulse LiDAR (MPL) sensors. ...

  • Brazil Needs Better Weather Data to Feed the World

    Brazil is the largest exporter of coffee, sugarcane, beef and crop-based ethanol biofuel, and the second largest producer of soybeans. Farming and agricultural products combine with food processing to comprise approximately 30% of the GDP. In 2017, Brazil’s agricultural sector grew by 13%, while the rest of the economy grew about one percent. Over the past thirty years, Brazil has seen a ...

  • Controlling natural gas usage costs – Case Study

    A large American engine manufacturer required mass flow meters to measure natural gas usage in each of the eleven buildings on their campus. Natural gas is used to fire furnaces and other equipment. Because each facility is a separate profit center, fuel and utility costs are allocated by building. They must also provide an accurate usage report of natural gas to the Department of Natural ...

  • Refinery tracks down costly air leaks – Case Study

    A refinery recently installed two new air compressors in their plant and specified two mass flow meters to measure utility air use and dry instrument air mass flow rate as well as total plant output. Their principal objective was to monitor increased air usage or temperature changes that might indicate a leak…a costly proposition. SIERRA’S SOLUTION The plant engineers ...

  • Introducing ozone to water purification – Case Study

    Traditionally, chlorine has been used to disinfect water for drinking. Unfortunately, chlorine produces carcinogenic by-products called trihalomethanes (THM’s) when it reacts with organic substances in surface waters. The recent adoption of the Surface Treatment Rules by the U.S. E.P.A. places strict limits on chlorine. Because ozone produces fewer disinfecting by-products, the EPA, along ...

  • Air usage data increases company profit - Case Study

    A large American container company required mass flow meters on their air compressor lines to help evaluate the efficiency of blow mold machines in their plant. The manufacturer melts PET chips and extrudes them through blow mold machines to produce plastic bottles for the beverage industry. Plant engineers need data on compressed air usage to help them reduce utility and production costs. Four ...

  • Choosing flow monitors for CEMS applications

    As a result of the 1990 Clean Air Act Amendments1, electric power plants must reduce their emissions of sulfur dioxide and nitrous oxides—the primary causes of acid rain. The U.S. Environmental Protection Agency (EPA), in its proposed rules2, designates the 111 Phase I fossil-fueled plants ^roughly 268 boiler units) that must have continuous emissions monitoring systems (CEMS) installed, ...

    How to bridge the financial gap in the WASH sector by helping water utilities become creditworthy? Annually, it has been estimated that approximately 114 billion USD must be spent in the WASH sector if the dedicated water goal, the Sustainable Development Goal 6 (SDG 6) is to be achieved by 2030 ...

  • New York City Tunnel No. 3 Surfaces with Steel Pipe Case Study

    The Problem Surface Connection Challenges In 2011, NYC’s Department of Design and Construction (DDC) sought to connect a reach of Tunnel No.3 to the city’s distribution system using 4 access shafts. Located in several high profile areas of Manhattan, including Lincoln Center, the Theatre District and Little Italy, the scope of work includes street ...

  • Tracking Air Pollution with Mini Micro Pulse LiDAR - Case Study

    Portable Monitoring Solution Offers Valuable Insight Into Haze Problem Poor air quality in large urban population centers has a negative impact on health and quality of life. To address these issues, the Institute of Urban Meteorology (IUM) in Beijing, China, is conducting fundamental research to better understand, forecast and mitigate atmospheric haze, i.e., air pollution. Over the past ...

  • Yorkshire Water uses AQUASCAN TM2 for trunk main leak detection - Case Study

    Introduction After initial meetings about suspected leakage and NRW losses with Craig Needham and Piotr Kozeil from Yorkshire Water a trial was arranged to use the GUTERMANN AQUASCAN TM2 correlator.
