I just realized this does forecasting and past weather too if you bring up the control panel by clicking 'Earth' (+/- 3 hours, +/- 1 day etc). I love it. If anyone here is a programmer (I am) you can actually find the source published on GitHub by the author:

github.com/cambecc/earth

It's tempting to add support for pulling data from various sources and allowing the user to switch between them for comparison (e.g. US NOAA vs. AU BOM). It looks like the BOM does provide data in GRIB format and you'd assume this would be more accurate than the US data. I'll have to see if I have the time or willpower to do it.

Below the gps co-ordinates what is the number in front of the "@_ _knots/kmh

Oh wow. Forum doesn't much like unicode :)
