Data are stored in ASCII

All values are integers
Pressures are stored as hectapascals (hPa) * 100
missing data are set to -32768

The month and year are stored at the start of each month.

Data Array (72x37)
Item (1,1) stores the value for the 5-deg-area centred at 180W and 90N
Item (72,37) stores the value for the 5-deg-area centred at 175E and 90S
The first and last lines are centred on the poles and the middle one covers 
2.5 degrees either side of the Equator.

The following Fortran fragment will read the month into MON, the year into IYR
and the anomaly values for the month into the integer array IANOM (72,37).
To get anomalies in hPa, IANOM must then be divided by 100.0.

The UNIT parameter is set as 10


	INTEGER IANOM (72,37)

1     CONTINUE

  	  READ(10,'( 2I6)',END=2) MON,IYR
	  READ(10,'(72I6)'      ) IANOM

      GOTO 1
