[ncl-talk] Remove SST data for specific area

[Dinuka Silva]

printVarSummary(x) is as follows.


Variable: x
Type: float
Total Size: 454377600 bytes
            113594400 values
Number of Dimensions: 3
Dimensions and sizes:   [time | 1753] x [latitude | 180] x [longitude | 360]
Coordinates:
            time: [15.49999..53340.5]
            latitude: [89.5..-89.5]
            longitude: [-179.5..179.5]
Number Of Attributes: 8
  lon2d :       <ARRAY of 360 elements>
  lat2d :       <ARRAY of 180 elements>
  _FillValue :  -1e+30
  standard_name :       sea_surface_temperature
  long_name :   sst
  units :       C
  cell_methods :        time: lat: lon: mean
  missing_value :       -1e+30
fatal:And: Dimension size, for dimension number 0, of operands does not
match, can't continue

It looks like "latitude" and "longitude" are 1D arrays . How can I make
them to be 2D arrays.

Dinuka.
