[Met_help] [rt.rap.ucar.edu #90066] History for station data in MET

[David Fillmore via RT]

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

Hi,
I am using point data to validate against model results. I am using AERONET
verison 3 data fiels and used ascii2nc tool to convert the data to netcdf
using the following command :

 ascii2nc 20180501_20180531_Dakar.lev15 Dakar_May2018.nc -v 5
Station data is for entire month and when I am trying to valiadate against
model data (from NOAA) for the very first hour it shows following error:

DEBUG 4: VarInfoFactory::new_var_info() -> created new VarInfo object of
type "FileType_Gb2".
ERROR  :
ERROR  : VarInfoGrib::add_grib_code() -> unrecognized GRIB1 field
abbreviation 'AOD_500nm' for table version 2
ERROR  :
But AOD_500nm is the name of variable header in observational netcdf file.

I have attaced raw aeronet data and config file for reference. Let me know
howwhat needed to be changed in the config file

Also, another question, how do I include multiple model forecast files
which are at 6 hour intervals to be compared against 1month point
observation and get pair observations for the time period ?

Thanks
Debasish

Hi Debasish -

Try in your PointStatConfig file (for AOD at 500 nm)

obs = {
field = [
    {
         name = "AOD";
         level = ["L500"];
    }
  ];
}

Let me know how far that gets ...
thanks,
David

thanks David. That worked and I used it against one model forecast
(006z of
first April), so it created the following stat files.

point_stat_060000L_20190401_060000V.stat
point_stat_060000L_20190401_060000V_eclv.txt
point_stat_060000L_20190401_060000V_sl1l2.txt
point_stat_060000L_20190401_060000V_cnt.txt
point_stat_060000L_20190401_060000V_fho.txt
point_stat_060000L_20190401_060000V_val1l2.txt
point_stat_060000L_20190401_060000V_ctc.txt
point_stat_060000L_20190401_060000V_mpr.txt
point_stat_060000L_20190401_060000V_vcnt.txt
point_stat_060000L_20190401_060000V_cts.txt
point_stat_060000L_20190401_060000V_sal1l2.txt
point_stat_060000L_20190401_060000V_vl1l2.txt

So, if I want to use entire month of model output to validate against
month
of point observations, I have to use 120 (assuming 4 model forecast
per
day) and I will have same number of stat files ? Is there any way to
concatenated them or writing in netcdf available in point stat ?

Thanks
Debasish
