For each CAO hour identified from interpolated sounding, a 36-hour back trajectory was calculated using the NOAA HYSPLIT model. We used three different meteorological data as inputs to HYSPLIT: GFS 0.25 deg, GDSA 1deg, and NCEP/NCAR Reanalysis. The trajectories were calculated at four elevations: 500 m, 1000 m, 2000 m, and 5000 m. Locations (latitudes and longitudes) for each hour of the trajectory were reported in the data files.
