[ncl-talk] Coordinate Subscripting

[Adam Phillips]

Hi Jalal,
Within your script you are calling cd_calendar, and then subsequently
calling day_of_year.
time at units = "days since 1998-1-1 12:00:00"
utc_date = cd_calendar(time, -5)
dyear = day_of_year(utc_date(:,0),utc_date(:,1),utc_date(:,2))

day_of_year will return numbers ranging from 1-365, and thus the values can
repeat if you have multiple years. This is not the type of array that
should be used for coordinate subscripting. I would recommend calling
cd_calendar, but retrieving the values in YYYYMMDD format, then assign this
array as a coordinate variable to your prc_reorder array:
delete(prc_reorder&time)   ; may not be needed
prc_reorder&time = cd_calendar(time, -2)

then you should be able to use the following coordinate subscripting to
plot:
plot = gsn_csm_contour_map(wks,prc_reorder({19980422},:,:),res)

Hope that helps. If you have any further questions let ncl-talk know.
Adam
