[ncl-talk] clmDayTLL problem

[Dennis Shea]

Well ....

If you have (say) model data that has 365 days per year then you can
associate an attribute to the input array

      yyyyddd at calendar = "365_day"    ; "noleap" etc

There are other calendars ... see below.

The reason for the 366 is that 'real' data using the gregorian calendar has
365 or 366 days per year.

  code snippet:

if (isatt(yyyyddd,"calendar")) then
       if (yyyyddd at calendar.eq."360_day" .or. yyyyddd at calendar.eq."360")
then
           ndys = 360
       end if
       if (yyyyddd at calendar.eq."365_day" .or. yyyyddd at calendar.eq."365"
.or. \
           yyyyddd at calendar.eq."noleap"  .or. yyyyddd at calendar.eq."no_leap")
then
           ndys  = 365
       end if
       if (yyyyddd at calendar.eq."366_day" .or. yyyyddd at calendar.eq."366"
.or. \
           yyyyddd at calendar.eq."allleap" .or. yyyyddd at calendar.eq."all_leap")
then
           ndys  = 366
       end if
       if (yyyyddd at calendar.eq."standard" .or. yyyyddd at calendar.eq."gregorian")
then
           ndys  = 366
       end if
   else
       ndys  = 366     ; default
   end if
