TrajStat plugin for MeteoInfo Java Edition

INTRODUCTION

  TrajStat is a free software plugin of MeteoInfo with some trajectory statistics functions.
  The trajectory calculation module of HYSPLIT (http://www.arl.noaa.gov/ready/hysplit4.html)
  was included in TrajStat as an external process to calculate trajectories. Monthly trajectories
  could be calculated in TrajStat, and the trajectories could be converted to GIS (Geographic Information System)
  line shape file. Cluster analysis function is included in the software. Measurement data could be added to the
  corresponding trajectories, so the trajectories could be selected according to the measurement data. 
  The software also can do PSCF (Potential Source Contribution Function) and CWT (Concentration Weighted Trajectory)
  analysis which is useful to identify pollution sources spatially for long-term environment measurement.

  It requires that Java 6 be installed on your computer. See the
  Java.com website for a free download of Java if you do not have it
  already installed.
