  • 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 ...

  • `Standards are desperately needed for plastic and pesticide contamination in soil´

    In addition to plastic in the oceans, plastic contamination in arable land throughout Europe and other parts of the world is a growing problem. No standards exist for these types of soil pollutants, nor for pesticide residues or their degradation products. For this reason, Professor Violette Geissen is calling for standards to be implemented. On 15 June, Geissen will deliver her inaugural address ...

  • Modeling for NAAQS Part 1: How to select the appropriate output for NO2

    The U.S. National Ambient Air Quality Standards (NAAQS) for 1-hour SO2, 1-hour NO2, and 24-hour PM2.5 use a very particular format. It is very important for all modelers (both within and outside of the U.S.) to understand how AERMOD handles this. In particular, U.S. users need to be familiar with the ...

  • 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 ...

  • Meteorological Technology World - Sensing Change

    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 ...

  • MIEX® Pretreatment to Micro & UltraFiltration

    There are currently (in 2006) four full-scale membrane plants in operation where the MIEX® Process pre-treats water prior to the membrane process. Two plants use Microfiltration (MF) and two use Ultrafiltration (UF). This technical note highlights the benefits of MIEX® Treatment prior to MF and UF based on operating data and experience at these facilities. In particular, data is provided from the ...

  • The Benefits of Micro Inverters

    The Benefits of Micro Inverters   In the solar world, one of the big debates is the whole string inverter vs. micro inverter issue.  Solar inverters are the devices that convert DC power being produced by the solar panel into AC power.  The debate lies in which type of inverter is better, string or ...

  • 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.   ...

  • 2005 Changing Climate: Canadian Meteorological Employment

    Recognizing the importance of quality meteorological services and information for Canadian industries and individuals, ECO Canada designed this study to determine the current and future human resource needs of the meteorological sector in Canada. In addition to the traditional meteorological sector, the study explored a wide range of allied business sectors, including transportation, ...

  • 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 ...

  • Effects of meteorological conditions on concentration of air pollutants in Delhi

    Air pollution in Delhi is a serious environmental problem. In this paper, the effects of meteorological conditions on local air quality are quantitatively assessed by determining the relationships between concentrations of Suspended Particulate Matter (SPM), Respirable Suspended Particulate Matter (RSPM), sulphur dioxide (SO2) and nitrogen dioxide (NO2) with meteorological parameters on monthly ...

  • 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 ...

  • Prediction of meteorological variables using artificial neural networks

    In the present study, artificial neural network (ANN) models are developed to predict seven meteorological parameters such as maximum temperature, minimum temperature, relative humidity, wind speed, sunshine hours, dew point and evaporation individually. To predict each of the meteorological parameters, recurrent MISO-ANN network is used. Totally seven ANN models are developed and the development ...
