<br>
Actually what I am doing is :<br>
<br>
(1) Calculate mean for the base period 1981-2010<br>
(2) Calculate standard deviation for the above period<br>
(3) Standardize the OLR anomaly by the following formula:<br>
<br>
(present OLR-base period mean) / standard deviation<br>
<br>
But I am not sure whether I am doing it correct or not. Because my<br>
result does not match with the standard value attached with this mail.<br>
<br>
I think the standardization method is different then what I am doing.<br>
<br>
I will follow your suggestion and let you know.<br>
Thank you<br>
