Hello:) At the moment I am searching for a way how to make one plot with matrix trajectories calculations at three different heights (in inputfile 1, 2 and 3 respectively) in different colors for each height level. I succeed in making matrix trajectories, and combining three different inputfiles int...

Thank you very much for this suggestion. How can I concatenate daily ARL files? Is there a particular command executable available for this purpose in hysplit?

back to work:) I uploaded the ARL formatted files for day 5 and 25 separately under the link https://copy.com/sQ9eTYvw7c8Q under the sub folders day05 and "day25" Hope these are useful. I presume there will be no problems with these files since they contain data for only 1 day; the problem as descri...

sorry for the delayed response, I am on holidays these days. I will send you the ARL formatted files as soon as I am back to work, by the end of August.

I checked the grib files with the "wgrib" program and I also read in the files with NCL. The files seem fine, there are no missing values and no "0" values. I suppose something must go wrong when the grib files are converted into the ARL format. I splitted the monthly grib files into daily files and...

Under the link https://copy.com/sQ9eTYvw7c8Q I placed the files chk-index-DATA-720x360-g3-k38-p0.txt and chk-index-DATA-360x180-g3-k38-p0.txt which contain the output of ./chk_index over the files DATA.ARL based on the ERA-Interim data with the 720x360 and 360x180 resolution, respectively. After day...

The different ERA-Interim (N128 gaussian grid) variables are combined into the three input files for HYSPLIT via: cdo merge ifile-var1 ifile-var2(etc,etc) ofile Then the ERA-Interim files are converted from N128 gaussian grid format to latlon format (let say resolution 360x180) via the following com...

Dear All, Currently I try to use ERA-Interim data to run hysplit. The conversion of ERA-Interim data (latlon format, 720x360) to ARL format goes well, however, when I run Hysplit, I encounter the following error in the simulation log: Model started ... HYSPLIT4 - Initialization USE: svn info | tail ...

We obtained the data via the MARS archive in a gaussian grid. I just found a solution that worked: to convert the data with use of cdo from gaussian to latlon projection with the following command: cdo remapbil,r720x360 {ifile} {ofile} With the ERA-Interim data in latlon projection the function grib...

What grid definition/resolution would you suggest? The ERA-Interim data files I used and sent under the link are in the default format: gaussian grid, N128 (128 gridpoints from pole to equator), in total 256 and 512 gridpoints in latitudinal and longitudinal direction, respectively.
