Hi,How to express the unit of an irregular period of time in the time coordinate variable in CF-netCDF? For example, for two 4-day periods: a) between 2007-01-01 and 2007-01-04; and b) between 2007-01-05 to 2007-01-08, which of the followings are correct?
1. time(time)=1,2 unit = "P 4 day since 2007-01-01"
2. time(time)=1,2 unit = "P4D since 2007-01-01"
There are names for regular time periods, such as week and fortnight, in
udunits.dat. For irregular time period, such as 3 days 1 hours and 5
minutes, I am not sure if we should use ISO 8601 expression, "P1M3DT1H5M"
or something like "P 1 month 3 day 1 hour 5 minute" as unit.
Thanks. Wenli ============================================================================== To unsubscribe thredds, visit: http://www.unidata.ucar.edu/mailing-list-delete-form.html ==============================================================================
