datem file format

[akp]

Hello,

I am writing code to reformat observations into datum format to be used for model statistics. I am wondering if the file needs header data to work properly or if the executable will work regardless of header data?

The header information is not used but the datem file will need to have 2 lines before it starts with the listing of the data.
The postprocessing programs read and skip the first 2 lines.

Thank you for the reply, I imagined that the header was unread but it looked well formatted.

My review of this topic continues since I now have my observations in datum format. I would like to run the following executables: con2stn, timeplot, c2datem, statmain, and scatter with the observations and model output. I have run con2stn and time plot with little difficulty but when I run c2datem I am getting odd output. I am using hourly observations and model output for about 60 hours but the c2datem output shows only 00z for each of the three days covering my period of interest. I don't know why it is doing this. The diagnostic file for c2datem shows only the 0 and 1 z periods as having data matches but no other time periods (see below). I am not sure why it is doing this. Could someone shed some light on this?

It seems that your data and your modeling results do not match in time. Can you please send us your CONTROL file and your datem file?

[akp]

I couldn't attach the files but I posted them here:
http://weather.hawaii.edu/vmap/hysplit/ ... al/CONTROL
http://weather.hawaii.edu/vmap/hysplit/ ... 272014.dat

[ariel.stein]

I see the CONTROL file but not the datem file. For some reason it does not allow me to get to your server. May be you can save it as a txt file.

[akp]

Sorry, I never checked the permissions. You should be able to view it now.

[ariel.stein]

Could you also send me the cdump and MESSAGE files?

[akp]

Unfortunately the MESSAGE file was deleted as part of the batch job when it completes but the cdump file is posted online at http://weather.hawaii.edu/vmap/hysplit/ ... ndividual/ named cdump.t00z.

Your CONTROL file contains comas. Please erase them. That is causing the problem.
