This function returns the coordinates of the boxes defining the
requested geographical regions selected for use in the IPCC AR4 of WG1.



Calling Sequence

Result = ipcc_regions( Shortname )


Shortname: A vector or scalar of strings containing the abbreviated
three letter names of the regions to request. Of length NREG.

Keyword Parameters

LAND: Returns a binary vector or scalar containing 1 if the region
is specifically for land only, 0 otherwise.
NAME: Returns a vector or scalar of strings containing the full names
of the requested regions. Of length NREG.
OCEAN: Returns a binary vector or scalar containing 1 if the region
is specifically for ocean/sea only, 0 otherwise.


Returns: Returns an array of size 4*NREG containing the geographical
boundaries of the boxes defining the requested regions. The
elements [*,I] contain the [ westernmost longitude, $
southernmost latitude, easternmost longitude, $
northernmost latitude ] boundaries for requested region I.




This function selects from the region information provided by David
Stainforth and David Sexton.


result = ipcc_regions( 'SSA', name=name )
This should return:
result = [-75,-55,-40,-20]
name = 'Southern South America'
