[ncl-talk] About local time (UTC+9)

[Rick Brownrigg]

Hi,

I'm not sure what you are trying to do, but this part does not seem right:

   do it = 0,ntimes-1                ;Loop for the time: it= starting time
      time = it
      time_numeric=cd_string(time(0),"%Y%N%D%H%M")

"time" would be an integer scalar (although in NCL, all scalars are arrays
of dimension 1, so notation like time(0) is not a syntax/semantic error),
but time certainly will not have the requisite "units" attribute.  Did you
perhaps mean to specify "ntimes(it)" in the call to cd_string()?

Rick
