I´m using a netCDF file for one year with data for every 5 days (73 time steps).
yes? Sh da
currently SET data sets:
1> .\dchl_ORCA2-levitus_DFS4_1958.nc <default>
Name title I J K L
DCHL Tracer as simulated… 1:360 1:180 1:31 1:73
I would like to get average values for every 3 month (Jan-Feb-Mar, Apr-may-Jun, Jul-aug-Sep and Oct-Nov-dec). I tried to use @ave transformation, but for some reason the results is not what I expected.
yes? let newDCHL=DCHL[L=1:72:18@ave] (I ignored the last day)
However the average value is not the same as 1:18@ave, 19:36@ave…
yes? list/i=1/j=1/k=1 DCHL[L=1:18@ave], DCHL[L=1:18:18@ave], newDCHL[L=1]
DCHL DCHL newDCHL
I / *: 1.864E-06 2.644E-06 2.644E-06
The value I was expecting is the first one. Why is that difference? And how can I regrid my data to get average values for every three months?
Thanks in advance
