HYSPLIT Forum: hysplitbbs.arl.noaa.gov

Hello, I intend to use the PC version of HYSPLIT to convert ERA-Interim 1 degree gridded data downloaded from http://apps.ecmwf.int/datasets/data/int ... evtype=pl/ into the ARL format using the Meteorology>Convert to ARL>ECMWF ERA menu option.However, when attempting the conversion, I received the following application error:
113
113
while executing
"exec $exec_dir/grib2arl.exe $arg1 $arg2 $arg3 $arg4 $arg9 $arg5 $arg6 $arg7 $arg8 >STDOUT"
(procedure "xtrct_data" line 60)

invoked from within
"uplevel #0 [list $w invoke]"
(procedure "tk::ButtonUp" line 24)
invoked from within
"tk::ButtonUp .eraarch.bot.save"
(command bound to event)

I used following data fields in the area of 90N, -90S, -180W, 180E (global),00:00:00 and 12:00:00(twice daily), 1deg, May 1979:

3d-grib:I downloaded 27 pressure levels (1000-100) with geopotential, rel. humidity, temperature, u/v wind and vertical velocity in 1 deg.(1.22G)

2d-grib: 2mtemp, 10m-u and v.

1d-grib: I downloaded surface pressure data (I didn't find the surface geopotential data. That is the reason?)

What does error:113 means? Does anyone have a clue on how to solve this problem? Thanks for help!

If you go into your hysplit4/working directory you will find a MESSAGE file you can open in notepad.
At the bottom will probably be a line "Input terrain height or surface pressure required"

The grib2arl code which is used by the GUI was originally designed to work with other ECMWF datasets (not ERA-INTERIM).
It works for ERA-INTERIM most of the time, but there are a few quirks.
In this case, it is not able to find your surface pressure data.

There is code which is called ecm2arl in the hyspit4/exec directory which you can run from the command line.
This should work. Please let me know if you try it and it doesn't.

Alternatively you can download the geopotential data here http://apps.ecmwf.int/datasets/data/int ... invariant/

Let me know how it turns out.

Cheers,
Alice

Hi, Alice

Thanks for your help!

The problem "Error:113" is coused by the surface pressure data I download for 1d-grib just as you said. According to your suggestion, I download the geopotential data from http://apps.ecmwf.int/datasets/data/int ... invariant/. Then, the GRIB data from ERA-interim convert to ARL format successfully.

Sincerely appreciate your help!

Yours sincerely
