History Reanalysis in WRF EMS 3.2.1 made easy [Guide]

[meteoadriatic]

Try to download files manually and put them in grib directory:

http://soostrc.comet.ucar.edu/data/grib/ecmwf/1996/07/

then use --local flag.

Thanks... into my /runs/domainname/grib directory? John

Excellent -- thanks meteoadriatic... that worked. John

I have a little problem with the ECMWF data taken from wrfems server.
I changed the name of the file as those that are on the server.
WRFEMS download them successfully, but when run ungrib "explode".
Any idea how I can fix?
It seems strange that Robert made available file can not be used.


*** Starting program ungrib.exe ***

You don't have proper vtable. Did you tried one from WPS 3.7.1 tarball?

How to make reanalyse with UEMS? FNL files are not supported.

Thanks!

Hi Meteoadriatic and others,

Thanks for the tips on reanalysis. In your example, you just run the reanalysis for a single day, but when you actually do this I assume you run this over and over changing the date each time. How do you do this? Do you write a shell script that will execute those over and over, perhaps using the ems_autorun_wrapper to trigger when the script runs?

Thanks

Sure it is so easy.

Let's say you want to run model during whole 2015, one run = one day.

Code: Select all

#!/bin/bash

firstYYYY=2015
firstMM=01
firstDD=01

DATE=${firstYYYY}-${firstMM}-${firstDD}

for i in {0..364}
do
   NEXT_YEAR=$(date +%Y -d "$DATE + $i day")
   NEXT_MONTH=$(date +%m -d "$DATE + $i day")
   NEXT_DAY=$(date +%d -d "$DATE + $i day")
   echo "Running ${NEXT_YEAR} ${NEXT_MONTH} ${NEXT_DAY}"

#ems_autorun --date ${NEXT_YEAR}${NEXT_MONTH}${NEXT_DAY} --cycle 00 --length 24 --dset ..........
done

Create that script, and run it. If you get 365 lines that say "Running year month day" you're good to go. Uncommend ems_autorun line and fill up what is missing... or use ems_prep followed by ems_run and so on if you prefer...

Of course you will need to add some lines below ems_autorun line that will handle finished products for each day.. I hope you will do that easy.

Hope this helps.

Yes meteoadriatic, anytime I can steal someone else's code that's a big help. Thanks a lot!
