About TraPSA Web Application

TraPSA is an open source web application for air pollutant potential source location apportionments. TraPSA performs trajectory ensemble receptor models using pollutant measurement and NOAA HYSPLIT trajectory data. TraPSA aims to provide the air quality community a user-friendly and powerful tool to:

Manage research projects,
Generate trajectory endpoints, and mixed layer height,
Analysis pollutant patterns,
Perform various trajectory ensemble receptor models, such as CPF , CFA , CWT , PSCF , RTWC , and SQTBA .

TraPSA is developed using Vue.js, combined with Python-Flask backend. D3.js, Plotly.js are used for the data visualizations, and the interactive map is provided by Mapbox .

If you find any issues with using this application, please firstly switch to Incognito windows as some plug-in may have unkonwn effect on it. If the problem still exists, please contact me.

Useful resources for getting started with TraPSA.

HYSPLIT

We provide a demo HYSPLIT 4 package, which can help you quickly run the example dataset. However, we strongly recommend that users register and install the most updated version of HYSPLIT software form NOAA in order to generate the most accurate trajectories. You can register and download here.

Thanks for using TraPSA!
