Hello,
I'd like to draw a Hovmoller plot from an output of model.
The data is saved every 6 hours starting from a particular
date and time (April 1 of the first year) in a GrADS format.
I was able to draw such figures with GrADS,
but I'd like to do the same in ncl (as easy).
I wrote a wrapper for reading direct binary in Gaussian coordinates
thus I/O is now not a problem.
Now I need to assign a coordinate variable to the time dimension.
When I draw a latitude-time section, I'd like to have dates as tick marks
rather than hours.
In another case I may even want it with pentads.
CCSM example pages seem to show only basic ones with a simple time axis.
Other tutorials showing assignment of the time coordinate variable show
an example such as:
time = (/ 1., 2., 3., 4., 5., 6./)
1. How date and time should be expressed and assigned?
2. Does a template, such as gsn_csm_lat_time automatically scale
hr/day/month?
3. How can I customize the coordinate labels?
4. Is there a way to deviate from Gregorian calendar, defined in
udunits.dat
and use the model month of 30 days?
I appreciate any help, suggestions, or pointer to FAQ, doc, examples.
