[gradsusr] OLR ANOMALY INDEX STANDARDIZATION

[Rekha Bharali]

Thank you for your prompt reply.

Actually what I am doing is :

(1) Calculate mean for the base period 1981-2010
(2) Calculate standard deviation  for the above period
(3) Standardize the OLR anomaly by the following formula:

                     (present OLR-base period mean) / standard deviation

But I am not sure whether I am doing it correct or not. Because my
result does not match with the standard value attached with this mail.

I think the standardization method is different then what I am doing.

I will follow your suggestion and let you know.
Thank you
