Preparation of Model Ready Meteorology Files: 16 November, 2017 - Online Course

This online event covers specific tools for generation of “model ready” meteorological data files for AERMOD. Consisting of pre-course consultation, live online training and a post course forum, this course is a must-attend event for air quality modellers in Australia and New Zealand. Early bird registration is available to 29 September. Standard registration closes on 3 November. Places are limited so please register early.

November 16, 2017
2 Hours


This course will focus on the difficult decisions and compromises that modellers make in generating met files and provide some practical tips and tools to help with the process.  The training is based on data which is available in Australia and New Zealand.

The training is designed to be an in-depth procedure for met data file preparation which is not covered by the generic meteorology course, nor the model specific training courses.

The online format includes a number of unique elements to enhance the training experience.  There will be an option for course participants to submit a case study or questions prior to the training event and the training will include admittance to a closed online course forum for one week after the event.

The course is complemented by the regulator requirements webinar to be held on 2 November 2017.  More information and registration is available here.

Pre-Course Consultation

Participants can submit case studies to the course trainer up to one month prior to the two-hour live session.  The trainer will assess the submitted case studies and present a selection during the training event.

Two-Hour Live Session: 1 pm – 3 pm AEDT

Part 1: Representative data

  • Discussion of what “representative data” means
  • Australia and New Zealand EPA Guidance, and where appropriate inclusion of USEPA requirements for comparison

Part 2: Data required by AERMET

Part 3: Resources for acquiring met data in Australia and New Zealand

  • EPA, Bureau of Meteorology, onsite met stations, TAPM, MM5 and WRF
  • Problems to be addressed: data gaps – how many data gaps impact on the integrity of the data? How much data is enough? What if the upper air data is from a different location or conducted at different times of the day to the regulatory guidance? Is it OK to use data from numerous sources?

Part 4: How to process a variety of meteorological data formats into AERMOD-ready files using AERMET

  • Stage 1, 2 and 3 data processing examples
  • How to obtain micrometeorological parameters
  • Problems to be addressed: How to deal with different averaging periods, eg 3 minute observations versus, hourly averages, versus hourly observations which are the average of the previous 10 minutes etc.

Part 5: Australian/New Zealand case study using BREEZE AERMET

  • Open a specific file format in AERMET
  • Set necessary parameters for the file
  • Determine land use characteristics for a site
  • Calculate micrometeorological parameters (e.g., surface roughness, albedo, and Bowen ratio) using manual and AERSURFACE methods
  • Create AERMOD-ready met data files
  • The case study will be demonstrated by the trainer during the online course. The input files, and exercise material will be provided to course participants following the online course.  Software will also be provided for the duration of the online forum.

Part 6: Data checking and validation

  • Practical tools for met file QA/QC
  • Trinity tips and experience
  • Use of MetView tool for data validation (The MetView software will be provided to course participants for the duration of the online forum)
  • Problems to be addressed: how to find erroneous meteorological conditions within your met file which may drive dispersion exceedances.

Part 7: Question and answer – where time permits, the course will be opened up to a question and answer session.

Post Course Online Forum

The online forum will be a dedicated subsection of the CASANZ website where participants can post questions/answers relating to AERMOD met file preparation.  The course trainer will review the forum on a daily basis and provide commentary and answers as needed.  The forum will be available for one week after the live session and is available exclusively for course participants.

Mr Brian Holland

Senior Scientific Software Specialist / Meteorologist, Trinity Consultants, Dallas.

Mr Holland serves in several technical roles in Trinity’s BREEZE Software and Data Services group, ranging from meteorological data processing to consulting on hazardous release modelling projects to software testing and requirements development.

Mr Holland is one of the primary environmental and safety modelers in the BREEZE group, with experience in areas ranging from air dispersion to explosion modelling.  He is experienced with the AERMOD, DEGADIS, INPUFF, and CALPUFF models, among others.  His modelling work includes clients in the oil and gas, mining, petrochemical, and other chemical industries.  He teaches Trinity’s AERMOD Modelling Computer Laboratory and Practical Air Dispersion Modelling Workshop, as well as accidental release and explosion modelling courses.  He also serves as one of the technical support personnel for the full line of BREEZE software products.  As the “Product Champion” for BREEZE AERMET and Incident Analyst, he is responsible for ensuring that those products correctly fulfill their scientific requirements and provide an excellent user interface.

As the lead member of the BREEZE meteorological data processing team, Mr Holland works with clients around the world to generate high-quality model-ready meteorological datasets that can withstand regulatory and scientific scrutiny.  He is experienced in generating input data for numerous models, including AERMOD, ISC3, and ADMS, and is able to use a variety of techniques to obtain a scientifically defensible data set, including use of similarity theory-based mixing height estimation, use of data from onsite meteorological stations, and merging of data from multiple sites.  He works with regulatory agency contacts to ensure that the most up-to-date approach is used in every dataset processed.

This course is aimed at experienced air quality modellers or people wishing to upskill in the modelling field.

  • Options for submitting pre-course case studies to the trainer
  • Admittance to the post course closed online forum
  • Access to the online course recording
  • Access to BREEZE AERMET and MetView software for the duration of the online forum
  • Access to the input files and exercise materials
  • The webinar is worth three Certified Air Quality Professional, continuing development points
  • The online course is worth three Certified Air Quality Professional, continuing development points
  • An electronic certificate will be issued to each participant of the online course.

At the conclusion of the course participants should be able to:

  • Identify meteorological data sources in Australia and New Zealand and assess whether the data is representative for the modelling location
  • Understand the steps required to prepare an AERMOD meteorology file using AERMET
  • Understand practical tools to deal with data gaps
  • Understand practical tools for meteorological file data checking and validation

The online course will use BREEZE modelling software; AERMET and MetView to illustrate the case studies and demonstrate data validation techniques.

MetView will be available to course participants for the course and duration of the online forum (1 week).

Although the course employs specific software, the learning outcomes are not limited to the software brand. The software is used as a tool to demonstrate the course concepts.
