Description Usage Format Details Examples

Description

This data set contains forward air trajectories calculated by HYSPLIT using the function ProcTraj for the date of 2010/06/10 (YYYY,MM,DD), from the Natural Resources Canada in Sault Ste Marie, Ontario, Canada. This data set was calculated with latitude and longitude equal to 46.503784 and -84.304442 respectively, hour interval of 1 hour from 00:00 am to 23:00 pm of 2010/06/10. Each air trajectory has 12 hours of duration, and starts at a altitude of 100 meters above ground.
