Multiple trajectory run in hysplit

[shipra]

Hello,

I am using the windows version of hysplit. I have wrf runs for 5 days at every 1 hour interval.

I have recorded the latitude, longitude and geopotential height of each grid point of the area under study.

Now I want to initiate a back trajectory analysis for 6 hr, released hourly after every one hour from these locations.

For. eg. I have the following grid points:

Lat=10, Lon=20, GPH=14430
Lat=11, Lon=20, GPH=14440
Lat=12, Lon=20, GPH=14440

at t=1

and similar data is recorded for t=2,3,4, and so on.

Now I want to initiate back trajectory (for 6 hour) after every 1 hr interval for each point.

Please give me a brief idea on how to achieve this or which functions to use.

Sincerely,
Shipra
