  • 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 ...

  • 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 ...

  • ´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 ...

  • 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 ...

  • Verification of wind energy related measurements with a SODAR system

    Abstract Complex terrain and growing wind energy converters (WEC) in wind parks generate increasing interest in determining wind profiles and turbulence besides the general forecast of annual energy production. Increasing hub heights and growing rotor diameters of advanced WEC make SODAR systems a valuable alternative to meteorological towers. SODAR systems provide wind profiles as well as ...

  • Applying hourly measurements of meteorological data and aerosol soluble ions in Taipei Basin, Taiwan

    This study applies observational data composed of hourly weather and aerosol to discuss the aerosol characteristics within different weather systems. Based on cluster analysis, spring weather in Taipei Basin 2004 was characterised as five weather systems: humid/low south wind speed, dry cold/high east wind speed, humid cold/east wind, dry cold/northeaster, and northwestern convection wind. Under ...

  • 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 ...


  • Measuring Offshore Wind Resources

    To select the right offshore wind site, estimate the future energy output of a wind farm, and determine the best layout for the turbines, project developers must conduct wind resource assessment (WRA) campaigns on site. This is a critical phase of the successful development of wind farms. WRA campaigns on terrestrial sites have traditionally been performed using meteorological towers equipped ...

  • Wind turbine controlling of the future

    Higher, more robust, more reliable: Parallel to the growing requirements for wind turbines, the requirements for monitoring sensors grow as well. But how can wind sensor manufacturers fulfil these wishes? And how should a future wind sensors look like? After analysing the current conditions and trends on the wind energy market, our CEO Klaus Hirzel compiled a wish list for future wind sensors. ...

  • A 2-D meteorological pre-processor for real-time 3-D ATD models

    Horizontal non-uniformity has important effects on the structure of the atmospheric boundary layer and, consequently, on pollutant transport and dispersion. These effects can be dominant in coastal sites or in the presence of complex terrain. Advanced 3-D atmospheric dispersion models can be used to calculate short-term pollutant concentrations in such complex situations. The use of new ...

  • Computational study of the effects of induced land use changes on meteorological patterns during hot weather events in an urban environment

    The heavy urbanisation of great cities has caused immense concern to societies due to air quality degradation and adverse changes in local climates such as abnormally high temperatures. Due to the growing demand for renewable energy resources and electrical power generation, the installation of photovoltaic (PV) panels on building roofs and other available open spaces has advanced in the recent ...

  • Meteorological simulations with use of satellite data for assessing urban heat island under summertime anticyclonic conditions

    The aim of this study was to investigate the formation, evolution and evaluation of topography effects on the urban heat island over the city of Zagreb. For this purpose, the non-hydrostatic mesoscale meteorological model MEMO was used and high-resolution simulations were carried out for two summertime anticyclonic periods. Satellite data were used to improve the model's performance. The ...

  • Simulations of the dispersion from a waste incinerator in the Turin area in three different meteorological scenarios

    A numerical modelling study for the assessment of the air quality impact of a waste incinerator to be built in the city of Turin is presented, aimed at evaluating the ground level concentration distribution during adverse dispersion conditions, causing severe pollution episodes. The pollutant impact of the incinerator is evaluated with the three-dimensional modelling system RMS. This class of ...

  • Effect of different meteorological fields on the regional air quality modelling over Pearl River Delta, China

    This study evaluates the performances of three Community Multiscale Air Quality (CMAQ) model v5.0 simulations that utilise meteorological input data from the 5th-generation Mesoscale Model (MM5), the Weather Research and Forecasting (WRF) model and WRF with Four-Dimensional Data Assimilation (WRF/FDDA). Three sets of CMAQ model simulations were performed for a high air pollution episode from ...

  • Relating geo–meteorological parameters to global solar radiation for Egypt by Iranna–Bapat's estimation models

    Estimation of solar radiation is considered as the most important parameter for the design and development of various solar energy systems. But, the availability of the required data is very scarce and often not readily accessible. The foremost objective of the present study was to estimate the monthly average global solar radiation (GSR) at various locations for Egypt, by the generalised ...
