[Met_help] [rt.rap.ucar.edu #80223] History for question about precip observations (UNCLASSIFIED)

Mon May 1 14:53:40 MDT 2017

----------------------------------------------------------------
  Initial Request
----------------------------------------------------------------

CLASSIFICATION: UNCLASSIFIED

I learned about a website which provides access to precipitation
observations on a 1km grid. I looked through the User's Guide (MET V5.2),
but could not find a reference to the use of these observations. I also
checked your website page at:
http://www.dtcenter.org/met/users/downloads/observation_data.php

The website I'm referring to is:
http://www.nssl.noaa.gov/projects/mrms/

I unpacked and explored one of the files called
"MRMS_RadarOnly_QPE_01H_00.00_20170419-150000.grib2.gz" and the accumulated
precip variable is named "RadarOnlyQPE01H" and not "APCP" which is the name
in the Stage II and Stage IV precip obs. 

Can these observations be used in MET?

Thanks.

John,

Yes, we do use the MRMS precipitation data for some the evaluation
projects
done in the DTC.  Take a look in this file to see the GRIB2 table
definitions for this data:
   met-5.2/data/table_files/grib2_mrms.txt

Thanks,
John

John - Thanks for confirming that. What if my model output doesn't
have the variable "RadarOnlyQPE01H"? Is this variable typically in the
post-processed WRF output? I'm not at work today, but I'll see if I
can check the UPP User's Guide to see if it can be specified for
output.

John,

No, that specific variable name won't be included in the WRF output.
Put
QPE means quantitative precip estimation... and you'd compare that to
forecasts of precip (i.e. APCP).  When setting up MET config files,
you'd
put APCP in the fcst dictionary and RadarOnlyQPE01H in the obs
dictionary.
