[ncl-talk] Spatial Power Spectra Density (PSD) Analysis

[dickson mbigi]

Hello!
I am looking for a code which can calculate and plot  PSD at every grid
point (i.e something which can do a loop through each grid point and then
selects at every single grid point the longest significant period from the
PSD and plot it). I went through NCL site and  find there is no NCL code
for the spatial (2-D)  PSD analysis (Available are only for the temporal
time series (1-D) data).
Note: I am using  SST(time,lat,lon)  data.

Along with this, I have attached
1. 1-D psd script and corresponding results. How can I modify to get
spatial (2-D) plot?
2. The spatial PSD map which I would like to plot.

Thank you.
