[Met_help] [rt.rap.ucar.edu #81009] History for One problem when I used ASCII2NC output file to do plotting.

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

Dear MET staff,
I am using METv5.2 to conduct my research. Now, I encounter one problem. I
want to use the output file (plot_test.nc) from ASCII2NC tool to plot a XY
plot via NCL. The x-axis is time series, which should be hdr_vld in
plot_test.nc. The y-axis is temperature: obs_arr (:,4) in plot_test.nc.
When I run the ncl to plot it, some mismatches occurred. After checking, I
found this is the problem of hdr_vld couldn't match the observation arrays.
Could you help me solve this problem? My input file: HKO_test.txt and
output file plot_test.nc have been uploaded to your server (Fei_data).
Thank you!

Yours,
Teng Fei

Teng,

I ran the script you sent and got the following error message:

fatal:Argument type mismatch on argument (1) of (gsn_csm_xy) can not
coerce
fatal:["Execute.c":8575]:Execute: Error occurred at or near line 29 in
file
this_is_the_script_I_used.ncl

The staff at the MET help desk really is not experienced with or
equipped
to support NCL.  However, I do believe that there is an NCL helpdesk
if you
need help.

This is the first I've heard of someone trying to process the NetCDF
output
of the ascii2nc tool.  Seems like it'd be simpler to just plot the
values
from the ascii input file.

Or you could run Point-Stat to verify your model against these
observations, and dump out the forecast/observation matched pair
values
(MPR line type).  Then, you could read the forecast/observation values
from
the MPR line type and plot them as a time-series.

Thanks,
John

John,
Thank you for your reply in details. I will try to ask NCL helpdesk.

Teng
