A European area pre-defined as 73.5/-27/33/45 can be specified as letter "E".
| value | comment |
|---|---|
E | Same as |
North/West/South/East | latitude/longitude coordinates of sub-area |
Areas can be defined to wrap around the globe, e.g. in order to retrieve all longitudes but Europe one would specify area=75/60/10/-20.

MIR can work with shifted grids, with no point at latitude=0, longitude=0. An example would be:
AREA=89.5/0.5/-89.5/359.5, |
|---|
This is done automatically provided the differences between N-S and E-W limits are both divisible by the corresponding increments without remainder. 
...
| NORTH = 90° | WEST = -180° | SOUTH = -90° | EAST = 179.5° |
...
area=75/-25/10/60
| NORTH = 75° | WEST = -15° | SOUTH = 30° | EAST = 42.5° |
