The HARRY_READ_ME.txt file

Part 7

7. Removed 4-line header from a couple of .glo files and loaded them into
Matlab. Reshaped to 360r x 720c and plotted; looks OK for global temp
(anomalies) data. Deduce that .glo files, after the header, contain data
taken row-by-row starting with the Northernmost, and presented as '8E12.4'.
The grid is from -180 to +180 rather than 0 to 360.
This should allow us to deduce the meaning of the co-ordinate pairs used to
describe each cell in a .grim file (we know the first number is the lon or
column, the second the lat or row - but which way up are the latitudes? And
where do the longitudes break?
There is another problem: the values are anomalies, wheras the 'public'
.grim files are actual values. So Tim's explanations (in _READ_ME.txt) are
