ncwa not adding history attribute

    Hi NCO users,

    I've noticed that ncwa isn't printing the history attribute in the output file when I average over a coordinate variable. For example:

    ncwa -a lat $infile $outfile

    Does anyone have an idea about this behavior? The history attribute isn't missing with other NCO operators. I'm running NCO 4.3.4.

    Hi Charlie,
    Thanks for fixing the ncwa history attribute - it's working for me using NCO version 4.3.8. However, ncra isn't adding the history attribute in this NCO version.

    I am experiencing a similar problem in ncea version 4.3.6, platform Mac OS. ncea does not append to a history attribute that is already present in the first input file.

    Does the recent bug fix for ncra also fix this ncea problem?

    Yes, Dave, the patch to fix the history attribute went in on 20131211. Will be in the next release 4.4.0 sometime soon.
