trajectory runs get stuck for ERA-interim meteo files

Post by ryanxia »

Hi All,

I am able to convert the ERA-interim meteorology files to ARL filesfor trajectory setup in HYSPLIT. I tried some different trajectory generation runs. I want to compare the ERA results with NCAR and GDAS dataset.
However, I could generate trajectory only for particular days. For example, I just set the starting time like at 16 12 10 05, then it could be run. But if I just change the date, to 16 12 13 05, then it could not be run. It get stuck. I don't know the reason. It will be like:

Model started ...
HYSPLIT4 - Initialization
Last Changed Rev: 854
Last Changed Date: 2017-01-12 10:47:54 -0500 (Thu, 12 Jan 2017)

NOTICE: using namelist file
SETUP.CFG

Calculation Started ... please be patient



Then, it get stuck. I wait with patience for 10 min but it doesn't go through the running. It is supposed to be finished within 2 seconds.
I randomly tried other dates, if set the start date to 16 12 12 05, it still could work; but if dry as16 12 14 05, it get stuck again. I could not understand why it happened. Why some starting dates could work, but some other not? It's really annoying.

Best,
Ryan

btw, if I run the daily run for that month using ERA meteo data, then I found error message for the days that cannot be run:

Hi Ryan,

Do you only have this problem with the ERA meteorological dataset?

Please let us know the operating system you are running HYSPLIT on.

Please go to your working directory (usually C:\hysplit4\working) and see if a file called MESSAGE was created and post the contents of the MESSAGE file here.
Please also post the contents of the CONTROL file (also in working directory) and if there is a SETUP.CFG file, please post that as well.

Thanks,
Alice

Hi Alice,

Yes. I only have problem with ERA metero files. I run NCEP/NCAR and GDAS and went successfully.

I am running HYSPLIT on Window 10.

Here I set the daily runs for 2008 January. Start day is 5; end day is 31; and start-hour is 12. I checked every meteorology output along trajectory. I kept every other thing in default as I re-installed the new version of HYSPLIT. Then the daily run got stuck at day 22. Daily run file during day 05 and day 22 were generated in working direcoty.

Here are the contents in MESSAGE file in working directory:

Re: trajectory runs get stuck for ERA-interim meteo files

Post by ryanxia »

Hi Alice,

I just thought about a possibility:

when I downloaded the ERA files, I set the area as default:

Default (as archived)
South Asia
Inter-tropical band
Northern Hemisphere
Southern Hemisphere
Tropical Pacific
Europe
North America
Indonesia
Custom

Is it because the default area doesn't include the area where the trajectory are inferred? Then probably there is no information for that area (grids).

I will try download the custom area files tomorrow. And then let you know if it works

You can check the geographical area coverage of your meteorological file with the GUI in meteorology/display data/Grid domain

Re: trajectory runs get stuck for ERA-interim meteo files

Hi,

I downloaded the "custom" for full global map ERA-interim meteorology data. I checked the data integrity through Displaying data in HYSPLIT. Although it only allows me to visualize the meteorological data for Day 1 in that monthly dataset, indeed I found there are data gaps in some particular small areas. But they are small.

I changed the starting location coordinate and all found that the daily run got stuck/terminated at Day 22 for 2008 January. I suspected Day 22 has big data gap in that ERA-interim monthly file. How do I know if it is true? How to handle and solve this trouble? I downloaded 1D, 2D and 3D files from ERA database and converted to ARL file following the instruction. I also tried other monthly dataset and comes to the same error message. Is it caused by the imperfection of ERA-interim data?

Best,
Ryan

The monthly datasets are probably too large. You will need to break them down into smaller chuncks.
Try to keep your grib files under 2GB.
See the following thread:

viewtopic.php?f=14&t=202&p=2779#p2779

You can use the profile program (either from command line) or in the GUI (using Meterology, display data, text profile).
Then put in the time offset and time increment and a location and you will get output from the ARL met file at that location
starting at your time offset and then every time increment forward.

Let us know how it goes.

Hi Alice,

Indeed, the text profile showed that everything is 0 after the day when the trajectory generation got terminated.
You mentioned using files less than 2GB. But my 1-degree ERA dataset was only 1.1 GB after conversion. You recommended "decomposing" the monthly dataset into smaller ones, e.g., weekly dataset. However, currently I found no way to decompose big file to smaller files. On ERA database web, they only provide monthly 3D 2D and 1D data. In the conversion program, I am only allowed to convert monthly 3D 2D and 1D ERA data into monthly ARL-readable meteo files.

Could you give some thread to "decompose" big meteo files into multiple smaller (weekly) files?

Great thanks. I was troubled by this for weeks.

Ryan
