Dear sir,I am a researcher in a university (Andhra Pradesh, India). I used
to download Hysplit reanalysis 7days back trajectory which help me in my
research work. but the problem arise when am downloading data of 01-07-2015
reanalysis 7days back trajectory, which is not showing in the 'plot' as
well as in 'trajectories endpoints'. It is showing only one day back
trajectory. please fix it or tell me any alternative method to get that
data sir. And one more is that i cant find data from 29-06-2015 to
30-06-2015 (reanalysis 7days back trajectories). please help me to solve
this problem sir..
I hope You respond positively to my request..
thanking you sir

That is because the file RP201507.gbl has only data for July 2015 and you are trying to go backwards from the 1st day in the file. You need to download the June 2015 file RP201506.gbl and add it to the files HYSPLIT uses. The same applies to why you cannot find the June 29 and 30 data, you need the RP201506.gbl data file.

There were some missing hours in the file. We fixed the issue and you should be able to perform your run.
