Preliminary investigations are indicating that the published 2.10
dataset has transposed the Vapour Pressure and Wet Day parameters.

Examples so far are from January and February 1981.

Month Param Min Max
Jan 81 VAP 0 310
Jan 81 WET 0 3220
Feb 81 VAP 0 280
Feb 81 WET 0 3240

I think the 310 and 280 values clinch it?

This applies to both the original GRIM format files and to the ones I
reformatted as grids (that program did one var at a time so could not
have swapped them, I've checked anyway).
