  • 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 ...

  • 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 ...

  • 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 ...

  • 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.   ...

  • 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 ...

  • Variability of PM10 concentrations dependent on meteorological conditions

    The influence of atmospheric exchange conditions on near-surface PM10 concentrations is analysed for four cities in the South-West of Germany in the period from 2001 to 2005. For each city, the PM10 data originates from roadside stations and Urban Background (UB) stations, that is, two types of official urban air quality monitoring stations characterised by different emission situations. The ...

  • Influence of meteorological factors on air pollution concentration for a coastal region in India

    A long-term study of measurement of concentration of NOx, SO2 and TSP pollutants have been done in a port and harbour region in India. Monthly measurements of gaseous and particulate pollutants were made at six monitoring stations from January 1997 to December 2000. Meteorological data was also simultaneously collected. In this study, the relationship between ...

  • Meteorological data from numerical weather prediction or observations for dispersion modelling

    Synoptic observations of wind speed, direction, cloud cover, precipitation and temperature are inputs to regulatory dispersion modelling. Numerical Weather Prediction (NWP) data generated by national meteorological services are easily formatted for dispersion models. Changing from observations to NWP data raises concerns amongst regulators and model users – how might impact assessments differ if ...

  • Meteorological network of weather stations trusts in Lufft sensors in Italy - Case Study

    Between 2009 and beginning of 2010 a huge meteo measurement network with more than 100 stations were build in the north and middle of Italy (Emilia Romagna, Ligurien, Toscana). The aim of the project was the extensively coverage for measurement of all important environmental data such as temperature, humidity, rain fall, wind speed and wind direction. The customer Autostrade per l'Italia ...

  • Surface ozone measurements and meteorological influences in the urban atmosphere of Istanbul

    Hourly measurements of ozone concentration in the urban atmosphere of Istanbul were carried out from February 1998 to July 1999. An assessment of the annual variations and relationships of ozone concentrations and meteorological variables was made. Annual variations were first examined without considering meteorological variables, and meteorological influences on ozone seasonal values were then ...

  • Interaction between air pollution and meteorological parameters in Erzurum, Turkey

    In recent years, the rapid increase in population density has caused increases in the consumption of fuel, and the outdoor air quality has deteriorated in the crowded urban areas of Turkey. Erzurum, a city in the eastern part of Turkey, is influenced by air pollutants such as SO2 and suspended particles. It is known that, in general, the air pollution concentrations have a close ...

  • Comparison of meteorological pre-processors during high-latitude winter conditions

    The performance of two meteorological pre-processors, which calculate the surface fluxes of heat and momentum from routine meteorological observations, was studied during two winter months at high latitudes, characterised by low solar altitudes and snow-covered surfaces, i.e. high albedo values. This, together with low temperatures and low wind speeds, causes stable stratification (often with ...

  • Evaluation of air pollution, local meteorology and urban public health

    The relationship between meteorological conditions and air pollution was assessed as a plausible explanation for respiratory health problems in Newark, New Jersey on the US east coast. Pollutants in both particle (PM2.5 and PM10) and gas phase (O3) were collected and analysed. We find that PM2.5 concentrations decreased by -30.8% (95% CI: -43.2%, -15.8%) when 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 ...
