EnviMan Planner Brochure - 2

P39 Planner www.opsis.se EnviMan Planner EnviMan Planner can be been used for simulation of various Air Quality scenarios in urban areas or regions. Typical applications include: Long term planning – Tra?c plans and city plans can be used to forecast Air Quality in terms of expected annual mean values and extremes. Data will be presented as colour patterns. What if… scenarios – Individual sources or groups of sources can be altered with respect to emission strength, emission heights, time variation of emissions etc and the Air Quality consequences can be studied/compared. Air Quality mapping – Mapping of today’s Air Quality pattern over the area – for supervision and to detect critical areas were monitoring stations ought to be located. Compatible with Emissioner Planner is completely compatible with Emissioner and all emission simulation tools found in Emissioner are supplied in the Planner module, where simulated emissions will be feeding the air quality dispersion models. Models and input data Planner includes a basic dispersion model – based on the next generation US-EPA regulatory model: AIRMOD, including atmospheric boundary scaling algorithms. In addition, a street canyon model is included for local dispersion calculation. Minimum requirements for model input data: – Emissions: Emission information set up by the module EnviMan Emissioner – Meteorological data: Wind speed, wind direction, air temperature and cloudiness/global radiation Additional meteorological information such as mixing height, vertical temperature gradient and wind pro?les can be used to improve modelling quality. Planner includes a time series database as well as a special user interface: the EnviMet module, to set up boundary scaling algorithms (providing parameters for the dispersion models) as a function of available meteorological data. Tools are provided to set up automatic import of meteorological data from the EnviMan ComVisioner or any external data source via a well-documented ActiveX (COM) interface. In addition, meteorological data can be exported/ imported via Microsoft© EXCEL 5/7 spreadsheets. Resolution Input data should be given as hourly values (meteorological data should be given as 10-15 minutes average values representing the hour) Output data is given as hourly values, representing actual periods or expected mean/extremes. Spatial resolution can be manually set using grid nets over the map area or part of the map area. Future enhancements The EnviMan Planner is designed following a modular strategy. Alternative models will be introduced during the coming years and tool-kits will be released for implementation of user supplied models.

Individual user areas and settings Year-2000 compliant with possibility of full storage of four digit year numbers Fully graphical user interface Automatic link to emission databases (created by Emissioner) Simulation results can be saved as documents for later reference and display Simulation results can be exported as images (JPEG, GIF etc) Presentation Map information can be altered using pre-set Mapset Set up of sheet presentation due to selected scale Zoom to rectangle Zoom in - according to pre-set magnitude Zoom out - according to pre-set magnitude Zoom to pre-set scale and position Move centre of map Scrolling Interactive co-ordinate presentation Emission presentation according to user de?ned colour tables (16 colours) 5 emission presentation symbols and 6 ?ll pattern styles Length and area computation All spreadsheets compatible with Microsoft Excel 5&7 Cut/Copy/Paste/Sort/Delete/Clear/Format/Font – in spreadsheet Time of day, day of week and date of month can be selected freely Dispersion Simulation Emission sources that can be used for simulation All types of sources represented in EnviMan Emissioner: point, area, line and grid sources Emission Simulation Constraint Substance choice Source type (Point/Area/Tra?c/Grid) Search key combination Emission class selection Air Quality Simulation Strategies Hypothetical cases i.e. using a prescribed combination of weather parameters (user supplied) and arbitrary emission scenarios (one source, many sources, any source combination). Real time period simulation. Any period during which meteorological data exists can be chosen. Air quality simulations will be sequentially computed and saved in documents for sequential or individual display. Statistical Period (sample). A mathematical/statistical processor is supplied and the user can set up scenarios re?ecting the typical weather variation during a season (winter summer, year etc). A representative statistical sample will be generated and the period can be used to simulate expected AQ mean values and extremes during the season. Simulation Resolution User can prescribe a grid net for the whole map are or any fraction of the map, including grid resolution in x and y direction as well as in the vertical. Output data will be computed and presented in the selected grid and presentation can be made at any scale. Output presentation and possibilities to save simulated information: Data can be displayed as colour maps overlaid the map of the area. Any user de?ned colour scale can be used (16 colours) and colours can be associated with concentrations as well as user de?ned descriptor words. Data can be computed/displayed in any user de?ned grid net and the map scale can be altered during the presentation Matrix numerical (spreadsheet) presentation. Export functionality Output can be saved as document Air Quality Models Basic models The next generation US-EPA regulatory model AIRMOD is supplied as the standard model. A boundary scaling processor based on US-EPA AIRMET is used, properly modi?ed for using meteorological data from a monitoring station based on alternative sensor combinations. Minimum con?guration: Wind speed, wind direction, air temperature and cloudiness/global radiation. Sensors should follow minimum requirements for U.S. EPA AQ–standards. Street canyon model. E?ects of the local emissions in a street canyon is described as a combination of a plume model and a box model following the concept of the Danish OSPM model. Tra?c induced turbulence is included. Modelling of concentrations in a street canyon can be performed locally for streets described in the emission database (EnviMan Emissioner). Additional Models Can be included as separate o?ers. Later releases of the Planner Modelling Tool Kit will allow users to implement locally developed models into the EnviMan concept. Import/Export of time series data: The EnviMet module A time series database is included in the Planner module – for storing meteorological data to be used for dispersion calculation Boundary scaling algorithms supplied for converting meteorological data to dispersion parameters. (minimum requirements: Wind speed/Wind direction/Air temperature and Global radiation or Cloudiness) Statistical data sample periods can be set up Import/Export via Microsoft © Excel 5/7 spreadsheets Import/Export via ActiveX (COM) interface Import/Export via ComVisioner Special features EnviMan Clipper included i.e: Selected map/presentation areas can be copied to clipboard and/or saved as ?les in the following formats: Windows bitmap/JPEG/GIF/PNG/Adobe Postscript II/Adobe PhotoShop bitmap.
