[Met_help] [rt.rap.ucar.edu #84327] History for Radar reflectivity and MODE

Initial Request
----------------------------------------------------------------
Hello,
I am a student at the University of Missouri. I typically use MET as a precipitation verification tool for my WRF simulations. Recently, one of my professors took interest in the software and would like to use MODE to compare radar reflectivities. The output comes from WDSS-II and is a .netcdf file. However, MET (v6.1) has trouble reading the file. Typically, I use UPP to process my WRF output and then PCP-Combine and Regrid-Data-Plane before MODE. I'm not sure how to do this with a WDSS-II file. Is there an easy fix to the error "trouble reading the file" and "cannot open file"? Is it even possible to compare reflectivity using MODE? All I can find online is the use of MODE to compare accumulated precipitation.
I appreciate your time and help.

Hi Chasity,
Could you please upload a sample NetCDF file to our anonymous ftp site
following these instructions?

I'll take a look and see if I have any suggestions.
Thanks,

Chasity,
Thanks for sending the sample file. I took a look and have a few
suggestions.
- Looks like your missing data value is -99900, but that isn't listed
as a
variable attribute. That should be defined as the "FillValue"
variable
attribute.
- If you file contained the actual lat/lon values, I'd suggest having
MET
interpret it as if it were a CF-compliant NetCDF file. Since it
doesn't,
let's add some global attributes so that MET thinks this is a file
that it
generated.
Here's what I did...
(1) Use ncdump to dump to ascii:
ncdump 20151213-064050.netcdf > 20151213-064050.ncdump
(2) Edit that ascii output as follows:
- Change "Lat" and "Lon" dimensions to "lat" and "lon"... seems very
silly
but unfortunately is necessary here.
- Add the _FillValue variable attribute to MergedReflectivity_020min.
- Add the valid_time_ut variable attribute to
MergedReflectivity_020min.
This is the valid time of the data in unixtime computed using the
timestamp from the filename with the unix date command:
date -ud ''2015-12-13' UTC '06:40:50'' +%s
- Add the following global attributes to define the grid information:
:MET_version = "V6.1" ;
:Projection = "LatLon" ;
:lat_ll = "39.7699317932129 degrees_north" ;
:lon_ll = "-93.3791427612305 degrees_east" ;
:delta_lat = "0.0044996440410614 degrees" ;
:delta_lon = "0.00578199652954936 degrees" ;
:Nlat = "384 grid_points" ;
:Nlon = "384 grid_points" ;
(3) Use ncgen to regenerate a NetCDF file:
ncgen -o for_met.nc 20151213-064050.ncdump
(4) Run the result through MET's plot_data_plane utility:
met-6.1/bin/plot_data_plane for_met.nc for_met.ps
'name="MergedReflectivity_020min"; level="(*,*)";'
And I attached a PNG version of the resulting image.
So yes, it's possible to use this type of data in MET. It's just a
question of how many hoops you want to jump through.
If you could get a radar composite that's already in GRIB1 or 2
format, MET
could read that directly.
Hope this helps.
Thanks,
John

Hi John,
I was able to follow your steps and recreate the image you created.
However, when I do the same for another file and try to compare both
using MODE, I get the "star found in bad slot" error. Is there a quick
fix for this?
Thanks,
Chasity

Chasity,
I wonder if perhaps you left the dimensions named "Lat" and "Lon"
rather
than renaming to lowercase "lat" and "lon"?" That would be an easy
detail
to miss and would result in the "star found in bad slot" error message
you
described.

John,
You are absolutely right. Thank you so much! Next time I'm in Boulder,
I'll have to shake your hand.
Enjoy the day!
