Wind Resource Monitoring Articles on Environmental XPRT

Amassing Wind Information

Wind is a variable resource, but not an indecipherable one. Second Wind encourages harnessing the full range of wind sensing technologies that are available today. When it comes to wind information, much attention is focused on the choice of wind measurement technology and data collection practices in wind resource assessment and project design. Right now, wind data plays a limited role in the ...

New methods for measuring the wind

Although computer models of wind flow over terrain have improved dramatically in the past few years, there is still no substitute for data recorded at the site. So you want to build a wind farm. Good for you. With the global drive towards a low carbon economy, it is surely the right way to go for many individuals, companies and, indeed, Governments around the world. As information from the ...

Urban sustainability issues — Resource-efficient cities: good practice

Our current pattern of resource use is leading to the depletion and, consequently, scarcity of natural resources (1), the degradation of ecosystems and volatile and increasing prices of natural resources. On a planet with finite resources, the challenge is to find a way of delivering greater value and more services with fewer inputs (EC, 2011a). Resources are defined as raw materials, such as ...

Construction and Civil Infrastructures Monitoring Systems

Civil infrastructures are usually monitored through its whole life cycle. SHM (Structural Health Monitoring) technologies enable the estimation of the structural state and detection of structural change that affects the performance of a structure. Two discriminating factors in SHM are the time-scale of the change (how quickly the state changes) and the severity of the change. These factors ...

The challenges and benefits of local air quality monitoring

A new generation of air quality monitors is now being offered to provide localised, real-time air quality readings – but the potential benefit is only just starting to be realised. It is generally accepted that whilst measurements from air quality reference stations are highly accurate, they are not sufficiently location-specific. Key pollutants – such as NO2 and PM2.5 ...

A case study for evaluating potential soil sensitivity in aridland systems

Globally, ecosystems are subjected to prolonged droughts and extreme heat events, leading to forest die‐offs and dominance shifts in vegetation. Some scientists and managers view soil as the main resource to be considered in monitoring ecosystem responses to aridification. As the medium through which precipitation is received, stored and redistributed for plant use, soil is an important factor ...

Soil CO2 Flux Measurements -- Addressing Spatial Variability: Determining the Number of Readings Required

Soils can be highly variable in terms of CO2 flux values. Even at a seemingly uniform site, the soil CO2 flux might range from 2 μmol/m2/s at one location to over 4 mol/m2/s just a few meters away. To obtain reliable site mean flux values, it is important to determine how many readings might be required so that time and resources can be properly allocated before starting an investigation. In ...

Intraurban variability of Ambient PM Arsenic and other air toxics metals case study

The Missouri Department of Natural Resources (MoDNR) and Washington University participated in a project to collect and analyze air toxics metals data. It was funded through a Community Air Toxics Grant from the U.S. Environmental Protection Agency (USEPA). The study grew out of the southside St. Louis Community Air Project (CAP) which identified six hazardous air pollutants of concern including ...

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 ...

Performance-Based Measurement Systems

Many of the Environmental Protection Agency's (EPA's) methods used to monitor air, water and soil for environmental contaminants prescribe step-by-step details on how the chemical analysis must be conducted and prohibit any deviations or variations. The EPA has recognized that monitoring equipment and technology have improved tremendously over the last few years; that environmental media do not ...

States propose attainment designations for the new 1-hour So2 NAAQS

The U.S. EPA revised the primary National Ambient Air Quality Standard (NAAQS) for sulfur dioxide (SO2) on June 2, 2010 by implementing a new 1-hour standard of 75 parts per billion (ppb) (calculated as the three-year average of the 99th percentile of the annual distribution of daily maximum 1-hour average concentrations). Based on an evaluation of the risks posed by acute exposure to SO2, EPA ...
