What is Air Dispersion Analyst (ADA)?
Air Dispersion Analyst is a click-to-run online platform that is designed specifically for air dispersion modelling analysis. Users can self-operate the platform and get results in a more efficient, reliable and flexible way.
Developed based on 10+ years Environmental Impact Assessment (EIA) project experience and supported by a large-scale parallel computing cluster, the platform achieves calculation speed of modelling far outpacing existing products with super low price while keeps high accuracy and stability.
Now it provides modelling for AERMOD Atmospheric Dispersion Modeling System, which is required in Tier 1 assessment of EIA Reports by Hong Kong Environmental Development Department (EPD). Other air dispersion models, such as Caline 4 will gradually be put to use in this platform.
Environmental consulting companies and research institutions, especially those having tight project schedule, or those with limited computational resources can benefit from Air Dispersion Analyst.
For other air dispersion modelling and also PATH-2016 assessment, we now provide off-line professional solutions.
