Initial Request
----------------------------------------------------------------
Greetings,
I'm finally getting around to testing MET to see how it works for WRF
verification. First, I want to try converting surface (MesoWest)
observations into the proper format for the input for ASCII2NC. I see this
on the MET website:
1. *Message_Type*
2. *Station_ID*
3. *Valid_Time* in YYYYMMDD_HHMMSS format
4. *Lat* in degrees North
5. *Lon* in degrees East
6. *Elevation* in meters above sea level
7. *Grib_Code* corresponding to this observation type
8. *Level* as the pressure level in hPa or accumulation interval in hours
9. *Height* in meters above sea level
10. *Observation_Value* in the units prescribed for the grib code
Do you have a small sample file I could view (that's often worth more than
a description)? There are things that aren't clear how to use, like
"Message_Type" or "Grib_Code".
Thanks,
Brandt/NWS San Diego

Hi Brandt.
A sample input file for ascii2nc is included in the distribution. If
using
version 5.0, you should be able to find it here:
met-5.0/data/sample_obs/ascii/sample_ascii_obs.txt
Here is a sample ASCII observation file we have used for testing. The
numbers don't mean much since it is just for software testing, but the
sample observations are for 12-hour accumulated precipitation at the
surface:
ADPSFC SID1 20050807_120001 40.00 -105.00 2001 61 12 -9999 1.01
ADPSFC SID2 20050807_120002 40.00 -105.00 2002 61 12 -9999 1.02
ADPSFC SID3 20050807_120003 40.00 -105.00 2003 61 12 -9999 1.03
ADPSFC SID4 20050807_120004 40.00 -105.00 2004 61 12 -9999 1.04
ADPSFC SID5 20050807_120005 35.00 -105.00 2005 61 12 -9999 1.05
ADPSFC SID6 20050807_120006 35.00 -105.00 2006 61 12 -9999 1.06
ADPSFC SID7 20050807_120007 35.00 -105.00 2007 61 12 -9999 1.07
ADPSFC SID8 20050807_120008 35.00 -105.00 2008 61 12 -9999 1.08
ADPSFC SID9 20050807_120009 35.00 -105.00 2009 61 12 -9999 1.09
The table of message types can be found here in the PREPBUFR
documentation:
http://www.emc.ncep.noaa.gov/mmb/data_processing/prepbufr.doc/table_1.htm
For the "surface" observations - meaning 2-meter variables (like temp,
dpt, pressure, rh) and 10-meter winds, use a message type of "ADPSFC".
MET matches point observations to the surface in a very
simplistic way... we're just mimicking the way NCEP does it.
Basically, if an observation has a message type of ADPSFC or SFCSHP,
it is considered to be at the surface. So when verifying 2-meter
temperature or 10-meter winds, the Point-Stat tool in MET only uses
observations with one of those message types.
Regarding the grib code, just use the code from the GRIB file output.
The "wgrib" command is very help for dumping the contents of a GRIB
file to the screen.
It will tell you what GRIB codes are contained in a file.
I hope this helps. Please let us know if you have any other
questions.
Thanks,
Julie

Julie,
Just wanted to check to make sure I didn't mess anything up. I
attached
both my input and output files (the ncdump on test.nc looked OK, I
think).
Thanks,

Hi Brandt. Thanks for checking in. I apologize for the delay - I was
out
of the office yesterday.
I took a look at your files. They look good. However, the grib code
should be an integer value. The value for TMP is 11. Here is a link
to
the grid code table:
http://www.nco.ncep.noaa.gov/pmb/docs/on388/table2.html
You could also find the grib code by using the "wgrib" or "wgrib2"
command. It will tell you what GRIB codes are contained in a file.
Please let us know if you have any other questions.
Thanks,
Julie

Thanks, Julie...I'll try that (and then eventually see how well the
PointStat tool works. Just a bit of the big picture--I'm eventually
planning on using this for verification of surface parameters of our
local
WRF at NWS San Diego (especially wind), but in the shorter term, I'm
doing
a project with Kyrgyzstan (Central Asia) where they are installing a
WRF,
and they very much will need verification (using the precious few
surface
obs they have).
Thanks,
Brandt

Thanks, Brandt. I'm glad to hear that you'll be using MET at NWS San
Diego
and for your project with Kyrgyzstan.
I'm going to go ahead and close this ticket. Please don't hesitate to
write to us with any questions in the future.
