TraPSA project

In this Section
The TraPSA (Trajectory-based Potential Source Apportionment) project was developed as a free, open-source toolkit for air pollution potential source locations apportionment analysis based on trajectory ensemble receptor models. TraPSA uses HYSPLIT, a state-of-art trajectory model developed by NOAA, to generate trajectory. TraPSA software is a powerful, graphical tool to help the air quality community use large monitoring and trajectory data for pollutant potential source location apportionment. TraPSA provides monitoring site database management, smart trajectory generation and handling, pollutant temporal pattern analysis, most of existing trajectory ensemble receptor models, and sufficient GIS editing functions.
