Meteorological data from numerical weather prediction or observations for dispersion modelling
Synoptic observations of wind speed, direction, cloud cover, precipitation and temperature are inputs to regulatory dispersion modelling. Numerical Weather Prediction (NWP) data generated by national meteorological services are easily formatted for dispersion models. Changing from observations to NWP data raises concerns amongst regulators and model users – how might impact assessments differ if ...

A dispersion model intercomparison archive
The paper introduces a formal archive for intercomparison of conventional regulatory dispersion models. It stems from an initial intercomparison, for the UK Environment Agency, of the USEPA's ISC and AERMOD models with the ADMS model, in common use in the UK. The objective is to compare the models directly with one another via standard test cases in order to reveal differences that may arise in ...

Onsite Meteorological Data - Everything You Need To Know
Most AERMOD dispersion modeling is conducted using meteorological data from a nearby airport. As long as the airport is reasonably representative of your source location, there is nothing wrong with that: airports are often a source of high quality data and located near major population centers and thus, major air pollution sources. But airport data isn’t always the best option for ...

Keeping the Increasing Complexity of Air Dispersion Modeling in Check
Driven by advances in scientific knowledge, tightening and constantly changing regulations, and higher-resolution raw data, environmental modeling is demanding more and more from EH&S professionals and their computers. AERMOD run times for large projects are measured in days rather than minutes and terrain data file sizes routinely exceed 100 MB. Modelers can increase productivity and keep ...

Designing and Implementing Perimeter Air Monitoring Programs
Perimeter or fenceline ambient air quality and meteorological monitoring programs have become increasingly valuable at hazardous waste, landfill, dredging, ports, and MGP remediation sites. Air quality monitoring programs protect public health and reduce owner liability related to excavation. When ...
