  • Quality assurance and improvement of micro-scale meteorological models

    Models have begun to play an important role in environmental assessment and urban climate studies. Their increasing use, however, is paralleled by a growing awareness that the majority of these models have never been the subject of rigorous evaluation. Consequently there is a lack of confidence in the modelled results. The paper reports on a European initiative (COST 732) which was launched 2005 ...

  • Modeling Tip: Importing & Exporting Traffic Data in CALRoads View

    The CALINE series of models was developed to estimate pollutant concentrations from motor vehicles at roadway intersections. It includes three primary models: CALINE, CAL3QHC, and CAL3QHCR. The latter allows processing of real meteorological data (up to one year) and input of vehicular emissions, traffic volume, and signalization (ETS) data. Data reflecting traffic conditions for individual hours ...

  • Wind Energy Production Estimates: Moving Beyond Time Averages

    No need to be a statistician to see that averages are often useful to compare different things. And yet, they often fall short as a true measure of performance. For instance, we use averages to compare the current weather against the climate normals or to get a sense of how our favorite sport team or player is doing. Team (player) statistics are a concise way of combining the scores from many ...

  • What can I use to filter my mobile phase?

    If you are using mobile phase that contains salts or, generally, any components that are weighed out for its preparation, you will need to filter the solution before using with HPLC or UHPLC. The most common type of filtration is membrane microfiltration. We sell an extensive group of products for this and they are discussed very well in a blog ...

  • ´More Stations. More Data. Better Forecasts.´ – the NYS Mesonet

    “More Stations. More Data. Better Forecasts.” – that’s the slogan of New York State Mesonet. The weather observation network consists of a total of 125 weather stations all over the state of New York and Lufft was selected as one of the vendors to support them in capturing the data. All 125 of the weathers stations have the standard instrumentation suite. Of those 125, 17 ...

  • The productive environmental laboratory: BSK Labs boosts efficiency with Metrohm IC

    BSK Labs runs a number of environmental laboratories and service centers along the west coast of the US. A total of 70 employees – including microbiologists, chemists, lab technicians, and support staff – make sure that the 200 to 350 samples that come in every week are analyzed. BSK Labs specializes in potable water chemistry, ground water monitoring, storm water runoff, solid waste ...

  • Two Detector Solution to Analyzing Sulfur

    Sulfur compounds are reactive, corrosive to pipes, and destructive to catalysts in petroleum refineries. Sulfur emission are strictly regulated globally. When released into the atmosphere sulfur dioxide converts to sulfuric acid resulting in adverse effects on human health and the environment. Sulfur detection is found useful in many other industries; therefore, detection of sulfur compounds in ...

  • Modeling Tip: How to Import BREEZE AERMOD files into BREEZE Risk Analyst for Human Health Risk Assessments

    Humans can be exposed to hazardous air pollutants (HAPs) either directly through inhalation or indirectly through ingestion or dermal contact, which can result in acute or chronic health effects. The risk of exposure varies depending on a number of variables, including the meteorological conditions, local geographical and emissions characteristics, the age of the individuals being exposed, and ...

  • Waterquality and meteorological data - Greece

    Background Thesprotia is one of the 51 prefectures in Greece and is located in the North-West of the country, 479 km from the capital Athens. The population of the prefecture is around 46,000 people. In the Pindos-Mountains arises the riverKalamas and empties after 115 km in the bay of Valtos (Ionian Sea). The river has large environmental influence on the area and is also in some areas ...

  • Meteorological Certification Feasibility Study 2007

    In 2004, in response to requests from the Canadian Meteorological and Oceanographic Society and the Meteorological Service of Canada, ECO Canada commissioned a major study of meteorological practice in Canada. The study was funded by Human Resources and Social Development Canada. The study discovered meteorological practitioners functioned in a diversity of scientific and technical fields ...

  • Verification of the meteorological pre-processor MEPDIM

    The Norwegian Institute for Air Research (NILU) has carried out a year of direct measurements of standard deviations of wind fluctuations (σv and σw) on an island off the west coast of Norway. These measurements have been used for the evaluation of estimated values based on the meteorological pre-processor MEPDIM. The physical basis for this metprocessor is provided by parameterisation ...

  • Sensitivity of CTM simulations to meteorological input

    The objective of this work is to investigate the sensitivity of an Eulerian Chemical Tranport Model to the reconstruction of the wind field. In the framework of City-Delta exercise, three 14-day simulations have been performed, using the same model (CAMx) and different meteorological inputs; these were built combining large-scale analysis, local observations and the output of a high resolution ...

    In the latest issue of Meteorological Technology World you can find a lot of information about our new optical sensors, the SHM30 snow height/depth sensor and the CHM15k cloud height sensor as well as the new product developments. Sensing Change... A new snow height sensor equipped with multipoint laser measurement technology – three separate modules to prevent data loss in ...

  • Effects of meteorological parameters on RSPM concentration in urban Delhi

    The adverse effect of Respirable Suspended Particulate Matter (RSPM) has become a well-recognised problem in environmental science. Dispersion and dilution of air pollutants are strongly influenced by meteorological parameters, namely wind, turbulence, and atmospheric stability. The analysis of Delhi's air quality data shows that winter is the most critical season with respect to the ...

  • Onsite Meteorological Data - Everything You Need To Know

    Most AERMOD dispersion modeling is conducted using meteorological data from a nearby airport.  As long as the airport is reasonably representative of your source location, there is nothing wrong with that: airports are often a source of high quality data and located near major population centers and thus, major air pollution sources.   ...

  • Validation of a mesoscale meteorological simulation over Po Valley

    Very high secondary pollution concentrations often occur in Northern Italy, due to the density of anthropogenic emissions and frequent stagnant meteorological conditions that characterise the area. In such a situation it is important to use Chemical Transport Models (CTMs), to properly describe phenomena bringing to pollution formation and accumulation. Meteorological models are one of the ...

  • The refinement of a meteorological pre-processor for the urban environment

    The meteorological pre-processor used routinely at the Finnish Meteorological Institute (FMI) has been modified in order better to represent urban conditions. We have re-evaluated the roughness length, introduced the zero displacement height and divided the surface layer into a roughness sub-layer and an inertial sub-layer. The friction velocity and Monin-Obukhov length are evaluated using an ...
