Model output data integration using a Web Map Server
Maps are one of the basic products that can be created from numerical model output data. Whether numerical weather prediction models, air quality photochemical models, air dispersion models, wave models or any other, it is useful to show in a map different fields like the air temperature, wind speed and direction, pollutants concentration, significant wave height or any other variable obtained ...

High resolution maps of nitrogen dioxide for the Province of Styria, Austria
Knowledge about the spatial distribution of NO 2 concentrations is beneficial for setting up air quality measurement plans, assessing exposure, or in licensing procedures, where background concentration levels are required. Styria (16.400 km², 1.2 million population) is the second largest province in Austria. In order to take topographical effects on the pollutant dispersion into account, wind ...

Noise mapping of industrial sources
Noise is often one of the environmental variables where it seems more difficult to guarantee full compliance with legal limits in complex industrial situations and/or in other multi-source environments. This paper describes the application of noise mapping techniques to industrial sources, such as factories, power plants, wind farms, showing the potential of its use, both at the design stage as ...

Dispersion model input parameters from numerical weather prediction or synoptic observations
Regulatory dispersion modelling uses hourly synoptic observations (OBS) from a nearby station. Alternatively, hourly Numerical Weather Prediction (NWP) data are useable in air quality management. In parallel runs, OBS data and NWP (two grid scales, ∼60 km and ∼12 km) were input to the meteorological pre–processor of the Met Office NAME III dispersion model. Frequency distribution results for ...

Further considerations on WAsP, OpenWind and WindSim comparison study: Atmospheric flow modelling over complex terrain and energy production estimate
This paper analyses Brazil’s most used wind assessment computational tools: WindSim, OpenWind and Wind Atlas Analysis and Application Program (WAsP). Each program produced a Wind Resource Grid (WRG) data base – through different methodologies – utilizing the same 5 anemometric towers, elevation grid and roughness map to generate it. The turbine layout was kept the same during all simulations and ...

Modelling emission, concentration and deposition of sodium for Poland
The aim of this paper was to calculate natural and anthropogenic emission of Na+ and to estimate, with the FRAME model, annual air concentration and deposition of Na+ for the domain covering Poland. Calculations of natural emissions included marine emission and wind blown dust from land. Anthropogenic emission was calculated for both point and area sources. Emission maps were used in fine ...

Superior Performance of Micro Pulse LiDAR for Aerosol Mapping Applications
Robert Rissland, Director, Int’l Sales for Micro Pulse LiDAR, explains the advantages of the polarized, single-photon detecting Mini Micro Pulse Lidar (MiniMPL) over Doppler Wind Lidar systems. For wide-area aerosol detection, differentiation and concentration mapping, the best tools for the job must offer autonomous continuous operations in varying weather conditions and collect reliable ...

Good Averages, on Average?
We all deal with averages every day without even thinking about it: has it been cold day, has it been windy? We intuitively form the overall perceived average temperature or wind speed to respond yes or no to those questions.If needed, we can also calculate a more exact average: take notes on the temperature displayed on a thermometer let’s say every hour, add the values, and divide by the number ...

Balancing the future of Europe`s coasts — knowledge base for integrated management
This report has three elements. Firstly, it gives a snapshot of the current state of Europe's coastal regions. Secondly, it assesses the policies used to manage coastal regions, and discusses the proposal for a new European directive to improve the management of coastal regions. Thirdly, it highlights the need for better information and better monitoring tools to help inform this management ...

Visualizing the stories data can tell
Scientists and technologists are turning numbers about everything from condors to ocean-floor contours into visual representations of environmental issues. We’re living in an era of Big Data, but too often it’s nothing more than a fire hose of numbers and data sets that most would have difficulty understanding. Increasingly, though, entities such as non-governmental organizations, ...
