Re: caveat on converts ERA to ARL format

Hi Miriam, I posted the same question in trajectory forum: https://hysplitbbs.arl.noaa.gov/viewtopic.php?f=27&t=1265 Alice said it is likely that the meteo file is too large and need to cut them into smaller chunks. I will try it later to see if that works. I also notice you had same question before...

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 sm...

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

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...

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

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 ev...

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

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: 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 ... p...

trajectory runs get stuck for ERA-interim meteo files

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 j...

Re: caveat on converts ERA to ARL format

Hi Alice, Thank you for your reply. Now I could easily convert ERA interim file to ARL readable. However, I have a new question about ERA meteorology files that I converted; it is supposed to be asked in trajectory model forum, but probably you could answer my question. I add converted ERA meteorolo...

caveat on converts ERA to ARL format

Hi, I am able to convert ERA-Interim to ARL-readable file for back trajectory analysis. However, I found there are several options before running conversion: 1. select projection conversion method 2. input a latitude and longitude If I choose Extract (set slider bars), what are the values of lat-lon...
