[ncl-talk] Regression

[Morteza Qadimi]

Hi;
I need to regress tropical Pacific SST with Nino 4 region SST and then substract it from original SST of tropical Pacific. But original SSTA data are 3D (time*lat*lon) and the regressed SST anomaly array is 4D. I can’t find out what is the problem. I’ve given some info about what I’ve done.

SSTA_Tropical_Pacific (468*11*86)
SSTA_Nino4_Region (468*6*6)
RC  = regCoef_n(SSTA_Tropical_Pacific, SSTA_Nino4_Region, 0,0)
printVarSummary (RC)

output ----------------------→
