Hi, I would like to use CFSR data to run backward trajectories. I saw that on the ARL archived server there is CFSR compatible-hysplit data for only a few dates of October 1994. So I'm guessing that it is possible to CFSR data. So I would like to know if anyone has already work with CFSR data ? and ...

Hi, I've been working lately on backward trajectories. I noticed that I ran isobaric trajectories, there's a variation of the level pressure along the trajectories. Since the method used is isobaric, the level pressure should be constant isn't it ? I was wondering if there were some kind of explanat...

I was wondering if it was possible to find further information about the vertical motion method for trajectories, especially for average data and damped magnitude.
thank your

I'm currently trying to convert ERA40 yearly dataset (dowloadn from ECMWF API data server), everything run perfectly except that when I'm checking the ARL file, only half of the year have been convert. Exemple : I download 3d, 2d and invariant file for the year 1961 (from the 1st of January to the 3...
