Query regarding back trajectory

Dear sir/madam This is a two parter question a) Can I get a little bit more clarity about the duration of time for back ward trajectory? E.g. in the recordings the time for backward trajectory is 68 hours. Is it 68 hours backwards from the starting date time of release of tracer? 2) Does HYSPLIT giv...

Re: Clarification on meteorological data

Sir/madam
I have a question regarding source geolocation.In the tutorial, a sampling data in form of DATEM format has been provided. How can I provide the same for my trajectory calculation? I have a GDAS file. Is it possible to obtain the data in a similar format?

Re: Clarification on meteorological data

Sir/madam I have downloaded the archived metrological file gdas 0.5deg resolution. I want to run a back trajectory analysis at 13 degrees N 85 degrees E location. How do I achieve this? Should I go to convert to ARL---> Global Lat lon and then set the desired coordinates? I have tried the same but I...

Re: Clarification on meteorological data

Sir/mam
there is no captex2_narr.bin on my PC. What should I do? Are there any other additional sources for downloading captex2_narr.bin file. This is with respect to finding absolute trajectory error.
