Hi friends,<br>
<br>
<br>
I would like to know if someone have a Grads Script to calculate a SVD<br>
of two different fields. I'm trying to construct a Atlantic Meridional<br>
Mode index based on method used by Chiang and Vimont (2004)<br>
(<a href="http://www.esrl.noaa.gov/psd/data/timeseries/monthly/AMM/" target="_blank">http://www.esrl.noaa.gov/psd/data/timeseries/monthly/AMM/</a>) but I<br>
don't have any script to do it here.<br>
