    What’s New in ADMS-Urban and ADMS-Roads 3.1? Upcoming release of ADMS 5

  • Lithuania User Group Meeting 2012

    Contents

    • What’s new in ADMS-Urban and ADMS-Roads 3.1? – Modelling odours (later talk) – Using .hfc, .igp and .nbr files – Lithuanian air quality standards – Other improvements

    • Upcoming release of ADMS 5 – Running AERMOD from ADMS input – Met data input – Comprehensive output file – Contour plots in ADMS Mapper – Other improvements

    • Summary

  • Lithuania User Group Meeting 2012

    What’s New in ADMS-Urban and ADMS-Roads 3.1?

  • Lithuania User Group Meeting 2012

    Using .hfc, .igp and .nbr files

    • In previous versions of the model files with data for hourly emissions (.hfc), intelligent grid points (.igp) and noise barriers (.nbr) were required to have the same name as the model input (.upl) file and to be located in the same directory as the .upl file

    • These files can now have any name and be located in any directory • To use these files:

    – The .hfc file must be referenced in the time varying emissions screen

    – The .igp and .nbr files must be specified in the additional input (.uai) file

    • When upgrading any model input (.upl) file that uses .hfc, .igp or .nbr files, this warning message may appear

    ADMS-Urban and ADMS-Roads 3.1

  • Lithuania User Group Meeting 2012

    Using .hfc, .igp and .nbr files

    .hfc files are used to model emissions that change for every hour of the year

    ADMS-Urban and ADMS-Roads 3.1

  • Lithuania User Group Meeting 2012

    Using .hfc, .igp and .nbr files

    The version number at the start of the .uai file has been incremented from 1 to 2. To use an existing .uai file in version 3.1, the version number at the start of the .uai file must be edited.

    .igp files are used to manage the number of intelligent gridding points added to road and line sources.

    .nbr files are used to model the effect of noise barriers on the concentration distribution from up to 100 road sources.

    ADMS-Urban and ADMS-Roads 3.1

  • Lithuania User Group Meeting 2012

    Lithuanian air quality standards ADMS-Urban and ADMS-Roads 3.1

    It is now possible to populate automatically the output table for direct comparison with Lithuanian air quality standards

  • Lithuania User Group Meeting 2012

    Other improvements

    1. A road can now be modelled as both a street canyon and a road with noise barriers

    2. The ArcGIS link is now supported for use with ArcGIS 10

    3. The MapInfo link is now supported for use with MapInfo 11

    4. For other minor changes refer to the “What’s New...” document in the ‘Documents’ sub-directory of the ADMS- Urban / ADMS-Roads 3.1 install.

    ADMS-Urban and ADMS-Roads 3.1

  • Lithuania User Group Meeting 2012

    Upcoming in ADMS 5

  • Lithuania User Group Meeting 2012

    Running AERMOD

    • In ADMS 5 there will be an option to run AERMOD using the data entered in the ADMS interface

    • ADMS sources allowed in AERMOD:

    – Point sources – Passive line and area sources – Volume sources

    Upcoming in ADMS 5

  • Lithuania User Group Meeting 2012

    Running AERMOD – met. input

    • Option 2 – Use ADMS met. data and specify an upper air file – Run AERMET – Run AERMOD

    • Three options for choice of meteorological data • Option 1 – Use ADMS met. data from interface – Run ADMS met. processor – Run AERMOD

    • Option 3 – Specify AERMOD input met. files – Run AERMOD

    Upcoming in ADMS 5

  • Lithuania User Group Meeting 2012

    Running AERMOD – allowed options

    • AERMOD cannot run all ADMS options • ADMS options always allowed in AERMOD:

    – Buildings (plotted) – Vertical met profiles – Time-varying emissions

    Upcoming in ADMS 5

  • Lithuania User Group Meeting 2012

    Running AERMOD – hills

    • Only terrain files can be included

    Upcoming in ADMS 5

  • Lithuania User Group Meeting 2012

    Running AERMOD – hills

    • Example output

    Upcoming in ADMS 5

  • Lithuania User Group Meeting 2012

    Met. data – hourly sequential data

    • Hourly sequential selected – met. data must either be: – hourly sequential OR – suitable for interpolation, in which case the model will interpolate

    the met. data so it becomes hourly sequential

    Upcoming in ADMS 5

  • Lithuania User Group Meeting 2012

    Met. data – requirements for interpolation

    • In order to be interpolated the input met. data:

    – Must contain year, day and hour and be in chronological order

    – Must not contain gaps larger than 9 hours

    – Must contain wind speed, wind direction and cloud cover

    – Must contain only variables which are able to be interpolated – a full list of these is given in the User Guide

    Upcoming in ADMS 5

  • Lithuania User Group Meeting 2012

    Met. data – met. interpolation

    • Allows you to model averaging times of greater than one hour if the input met. data is sequential but not hourly sequential
