Re: More Climatology Stuff... Diurnal Cycle over a Month
Hi Jeremy,
If I am understanding your question, it's easy done. Here, by example
...
! before we can show an example we need a test variable (substitute YOUR
data)
define axis/t=1-jan-1980:31-dec-1989:1/units=hours tdata
let test_data = RANDU(t[gt=tdata])
! start by defining a 24 hour "modulo" axis
define axis/t="1-jan-0001:00:00":"1-jan-0001:23:00":1/units=hours/modulo
t24hr
! now create a diurnal (24 hour) variable from a particular month of
your data
let particular_month = test_data[t=1-mar-1985:31-mar-1985]
let monthly_diurnal_cycle = particular_month[gt=t24hr@mod]
! the result
! note the label "01_JAN" can be considered an arbitrary 24 hour period
list monthly_diurnal_cycle
! or 3 cycles repeated in a plot ...
plot/l=1:72 monthly_diurnal_cycle
Hope this helps ...
