Ocean basins dataset



All,

I've recently needed to generate some ocean basin masks and thought I'd share the result.

Starting with the dataset submitted to the ferret users group by Jim Orr
http://ferret.pmel.noaa.gov/Ferret/Mail_Archives/fu_2004/msg00323.html
I modified it slightly and now offer up the following dataset:
http://ferret.pmel.noaa.gov/cgi-bin/nph-dods/data/Basins.nc
This dataset has the following variables:
 ATLANTIC Atlantic Ocean Mask              1:360     1:180     ...       ...
 PACIFIC  Pacific Ocean Mask               1:360     1:180     ...       ...
 ARCTIC   Arctic Ocean Mask                1:360     1:180     ...       ...
 MARGINAL_SEAS
          Marginal Seas Mask               1:360     1:180     ...       ...
 INDIAN   Indian Ocean Mask                1:360     1:180     ...       ...
which are defined as 1 in the named ocean basin and missing everywhere else.

Here's an example plotting time series of SST for the entire Indian Ocean:
use "http://ferret.pmel.noaa.gov/cgi-bin/nph-dods/data/Basins.nc"
use "http://ferret.pmel.noaa.gov/cgi-bin/nph-dods/data/coads_sst.nc"
let indian_sst = sst * indian[d=1,gxy=sst[d=2]]
set region/t="15-jan-1960":"15-jan-1990"
plot indian_sst[x=@ave,y=@ave]
Enjoy!
