Hello,
I'm trying to modify the wind components of a meteo data using a wind profile derived from observations. I think the routine add_data is what I'm looking for, but I cannot produce the new meteo file.
Attached the observation file (observation_input_file.txt).
I'm running the following command:
./add_data observation_input_file.txt extract_26568.bin -d -z1
and I get the following output on screen:
NOTE: All grid points will be modified by observations
Number of INDX records: 3
First time period in gridded file (YY MM DD HH MM): 18 12 22 0 0
Last time period in gridded file (YY MM DD HH MM): 18 12 28 21 0
Temperature will be blended: T
Turbulence will be blended: T
Loaded data for # time periods: 1
Loaded data for max # stations: 1
Loaded data for max # data lvl: 6
Number of time period in observational data: 1
Skipping observations at: 18 12 24 16 0
The only output file that I get is a MESSAGE file (attached).
Is there anything I'm doing wrong?
Many thanks for any help you can give me.
Best
Federica

Re: add_data routine
The date/time of the observation (Dec 24, 16 UTC) is before the start of the meteo file (Dec 22, 00 UTC).
Re: add_data routine
Thanks!
Setting the observation time equal to the start of the meteo data I can produce the new meteo file.
However, I still get this error:
Station outside of gridded file boundary (lat,lon): 37.00 15.00
The problem is that those points are inside my domain.
Thanks again for you help

Re: add_data routine
Are you using a lat-lon grid? The program add_data is designed for a conformal grid, not a lat-lon grid.
Re: add_data routine
Yes, I'm using a lat-lon grid. So, is this a problem of the wind-field that I'm using (in this case a GDAS 1.0 deg) or of my lat-lon point? I tried with different wind-fields, but I still get the same error.
Many thanks for your help!

Re: add_data routine
It's a problem of the meteorology data (gdas1). For example a lambert conformal grid would work.
Re: add_data routine
I've tried with a lambent conformal grid and it worked.
Many thanks!
Many thanks!
