I am having trouble computing correlations for data-sets with different
resolutions, different time spans and different gridding points.
In particular,
I have
a) SST Data - x=0E:0E,
y=40S:40N, # x points:1,1440; #y points:1,320
time steps: 1 July 99 to 31 Jul 01
b)Scat. Data- x=0.5W:0.5W, y=85.5s:85.5n,# x points:1,171
#y points:1,171, time steps: 20 Jul 99 to 04 Nov 01
c)Precip dat- x=0E:0E, y=90s:90n, # x points: 1:360,
# y points: 1, 180, time steps: 1 Jan 98 to 31 Aug 01
For correlation of data in b) with c) I defined a new grid for the precip variable:define axis/x=0.5E:0.5W:1 xax
Then I define new variables for the region/matching time I wanted to perform the correlation over :
LET p = Precip_w[d=2, x=120e:70w, y=50s:35n,l=943:1704] NOTE:
(both variables begin on 20 Jul 99
LET q = U[d=1, x=120e:70w, y=50s:35n,l=13:774]
and end on 31 Aug. )
list/x=170e:180e/y=10s:15s/l=1 p, q
However, I get the following errors:
*** NOTE: Invalid L axis limits ignored: P
*** NOTE: Invalid L axis limits ignored: Q
**ERROR: inconsistent sizes of data regions: X axis
Variable 2 is
I=171:181
expression is
I=171:180
list/x=170e:180e/y=10s:15s/l=1 p, q
Command file, command group, or REPEAT execution aborted
Is there a different direction I should take for this type of problem?
Do I have to re-write the data into matching time steps? Would greatly
appreciate your help on this question.
