Re: Does ncl give the right time span for this netcdf file?

Lin,

More info is needed. Please show the full results of
printVarSummary(time) after the statement that reads "time" from the
Netcdf file.

However, the initial symptoms strongly suggest that that version of
ncBrowse does not correctly handle the "noleap" calendar, and the
NCL calendar function is doing it correctly.
