• 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

• Summary


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


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



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




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.



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


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.



Upcoming in ADMS 5


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


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


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


Running AERMOD – hills

• Only terrain files can be included

Upcoming in ADMS 5


Running AERMOD – hills

• Example output

Upcoming in ADMS 5


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


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


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

• 00:00 01/01/2011 • 03:00 01/01/2011 • 06:00 01/01/2011 • 09:00 01/01/2011 • 12:00 01/01/2011 • ...

Upcoming in ADMS 5


Grids – multiple z levels

• Option to obtain output at multiple heights moved from .aai file to interface

• The levels.glt or levels.gst files contain concentration output

Upcoming in ADMS 5


Grids – multiple z-levels example output

• Use this option now to – Plot contours at multiple heights (ADMS contour plotter) – Plot vertical concentration profiles (Excel) – Plot vertical slices (combination of Excel and Surfer)

•0.0

•10.0

•20.0

•z(m)

Upcoming in ADMS 5


Output – maximum daily concentrations

• New feature to specify maximum concentration within each day – Max. value calculated over averaging periods ending on that day – For long term output used in percentile and exceedence calculations only

Upcoming in ADMS 5


• Comprehensive output file containing concentration (and deposition) data at each output point for every met. line for each long term output

Output – comprehensive output file

Upcoming in ADMS 5


Output – comprehensive output file utility

• Comprehensive output file utility – Interactively calculate and view concentration/deposition for any

averaging period – Post-process output based on a set of air quality standards

• Highest values and date/time of occurrence • Exceedences and duration of longest exceedence

Upcoming in ADMS 5


Output – user-defined air quality limits

• Enter air quality limits in output table and click Save...

Upcoming in ADMS 5


Output – user-defined air quality limits

• Saved file can then be selected from the drop-down list

Upcoming in ADMS 5


Utilities – met. converter with upper air data

• Converts US NOAA/NCDC or AERMOD format surface meteorology files to an ADMS format .met file

• Incorporates upper air data to specify the buoyancy frequency above the boundary layer

Upcoming in ADMS 5


Utilities – ADMS Mapper • ADMS Mapper displays sources, buildings and output

locations • Background layers can be imported • Can export layers

Upcoming in ADMS 5


Utilities – ADMS Mapper • ADMS Mapper will include integrated gridding capability for

creation of concentration plots • No need for 3rd party software

Upcoming in ADMS 5


Utilities – plotting and animation

• Automated plotting tool – Excel spreadsheet linked to Surfer, provides a quick method for

creating multiple contour plots

• Animation tool – Excel spreadsheet linked with ImageMagick for converting a

sequence of .gif files into an animated .gif

Upcoming in ADMS 5


Utilities – animation Upcoming in ADMS 5


Future developments

• We plan to include capabilities to – calculate wind energy from turbines – model the effect of buildings on turbines – model the effect of turbines on dispersion
